Repair or Replace My Electronics?

Should I Repair or Replace My Electronics?

The judgement behind the numbers — which faults are worth fixing on TVs, laptops, phones, tablets, games consoles, monitors, and audio equipment.

The framework gives you five rules. The databases give you the two numbers those rules need — expected lifespan, and repair cost by fault.

This page is the judgement in between, for electronics specifically.

Electronics work differently from appliances, and it’s worth understanding why before you apply the rules. A dishwasher fails in one of a handful of ways, and the same faults recur across every brand. A TV, a laptop, a phone, and a games console have almost nothing in common mechanically — they fail in completely different ways, over completely different timescales, with completely different repair economics.

So this page is organised by failure pattern rather than by device. Once you know which of the three patterns you’re facing, the decision is usually made for you. Then each device section applies the pattern to the specific machine.

The three failure patterns

Almost every electronics repair-or-replace decision falls into one of three categories. Learning to recognise which one you’re facing is worth more than any individual cost figure, because the pattern determines the decision before you’ve priced anything.

Pattern 1: The panel or screen

Examples: a TV panel, a laptop display, a phone screen, a tablet screen, a monitor panel.

The verdict: usually replace on anything past its first few years. A replacement panel or screen costs a substantial fraction of a new device — and on a TV specifically it costs nearly as much as a new set.

This is the terminal failure in electronics. It’s the equivalent of a fridge compressor or a dishwasher control board, except it arrives more often, on cheaper devices, and on screens that crack rather than fail.

The exception that matters: a cracked phone screen isn’t the same as a failed TV panel. A phone screen at $200–$450 against a $900 phone is 22%–50% — a repair on anything under three years old. A TV panel at $700 against an $800 set is 88% — always a bin. The pattern is the same; the arithmetic isn’t.

How to tell whether you’re facing a panel fault or something cheaper: a panel fault produces symptoms that are consistent and structural — dead bands, lines that don’t change, uniform discolouration, physical cracks. A board fault produces symptoms that vary — intermittent lines, flickering, working-then-not. If the symptom changes when you press the bezel or open the menu, it’s usually not the panel.

Pattern 2: The board

Examples: a laptop motherboard, a TV main board, a games console board, a phone logic board, a monitor power supply.

The verdict: depends entirely on age. A $180 main board on a three-year-old TV is a repair. A $450 motherboard on a six-year-old laptop is a bin.

The board is where the 50% rule and the lifespan rule most often disagree. The cost test says repair; the lifespan test says replace. And in electronics, the lifespan rule usually wins — because device lifespans are short, and a board failure at year five on a device that lasts six years is buying almost nothing.

The exception: a board repair that costs under 25% of replacement passes both tests on almost any device. A $150 board on a $900 laptop at year three is 17% — a repair regardless of age.

Pattern 3: Everything else

Examples: batteries, charging ports, fans, storage drives, buttons, speakers, hinges, thermal paste.

The verdict: almost always repair. These are the parts that cost $20 to $200, and they’re why most electronics are repairable at all.

This is the largest category by frequency and the one where people most often make the expensive mistake — replacing a device over a $40 battery or a $30 charging port. A battery is the cheapest way to extend a laptop or phone’s life. A charging port is the cheapest fix on any device. A fan and thermal paste is the cheapest fix on any overheating machine.

The rule of thumb: if the repair is under $200 and the device is under five years old, it’s almost always worth doing. Below that threshold, neither the 50% rule nor the lifespan rule rejects repairs often enough to worry about.

The pattern by device

The pattern is consistent: the panel is terminal, the board is borderline, and everything else is worth fixing. What changes between devices is how long you have before the lifespan rule starts rejecting repairs.

Televisions

Typical lifespan: 7–12 years for LCD, 5–10 for OLED. The panel is the limit — everything upstream of it is repairable at $30–$200.

The decision repair: the panel. It always costs nearly as much as a new set, which is why the fault type alone decides the outcome before cost is even considered. Vertical lines, black spots, or a cracked screen mean replacement.

Everything upstream of the panel passes. A T-Con board at $100–$250, a main board at $180–$350, backlight strips at $250–$450 on a premium set — all comfortably under the 50% line on a TV under eight years old.

Fault-by-fault costs

Where the brand changes the answer

OLED is the exception. LG and Sony OLED panels degrade gradually — brightness decline is normal and expected — but panel uniformity faults are terminal, and an OLED panel costs close to a new TV.

Before assuming an OLED fault is unrepairable, check the warranty. OLED panel coverage has historically extended beyond the standard TV warranty in some regions, and a covered panel replacement changes the entire calculation.

Budget brands — Hisense, TCL, and the store labels — fail earlier on the backlight, which is the one repair that sits close to the 50% line on a cheap set. A $350 backlight repair on a $400 TV is a bin; the same repair on a $1,200 set is a repair.

A worked example

A four-year-old LG TV, showing vertical lines. The T-Con board has failed. Part $60, installed quote $200.

Against an $800 comparable replacement: 25%. Lifespan used: roughly 40–50%. Repair. Vertical lines almost never mean the panel is dead — the T-Con and ribbon cables are the common causes, and both are cheap.

The same TV with a failed panel, quote $700 against an $800 replacement: 88%. Bin.

Laptops and computers

Typical lifespan: 4–7 years for laptops, 6–10 for desktops. The battery and hinge decide it, not the CPU.

The decision repair: the motherboard — and on a laptop past five years it usually fails, because the lifespan rule rejects it independently of the cost. At $300–$600 installed against a $400–$2,000 replacement, that’s 15% to 150%.

Everything else passes. A battery at $120–$250, a charging port at $100–$200, a screen at $200–$450, a keyboard at $120–$250 — all worth doing on a laptop under five years old, and all cheap enough that the lifespan question rarely matters.

Fault-by-fault costs

Where the brand changes the answer

Business laptops last longer and are easier to repair. A ThinkPad or Dell Latitude at six years is a different proposition from a consumer laptop at six years — parts are available, the service manual is published, and the machine was designed to be opened.

MacBooks sit in the middle. The battery and screen are serviceable, but the logic board is expensive and the storage is soldered on most models, which removes one of the cheap repair options. On a MacBook, the motherboard question arrives with fewer alternatives.

Budget consumer laptops at $400–$600 new are the tightest calculation in the category. A $250 screen repair on a $450 laptop is 56% — a bin — even though the same repair on a $1,200 laptop would be a clear repair.

A worked example

A four-year-old laptop, won’t hold a charge. The battery has failed. Part $60, installed quote $140.

Against a $900 comparable replacement: 16%. Lifespan used: roughly 60–80%. Repair. A battery is the cheapest way to extend a laptop’s useful life, and it’s almost always worth doing on anything under five years old.

The same laptop with a failed motherboard, quote $400 against $900: 44%. Passes the cost test — but the machine is at 70–100% of expected life. Bin.

Phones and tablets

Typical lifespan: 3–5 years for phones, 4–6 for tablets. OS support, not hardware, is usually what ends their useful life.

The decision repair: the screen — and unlike a TV panel, a phone screen is genuinely worth replacing on anything under three years old. At $200–$450 installed against a $300–$1,200 replacement, that’s 17% to 150%. On a current iPhone or Samsung flagship it passes comfortably; on a budget phone it fails.

Everything else passes. A battery at $120–$250, a charging port at $100–$200 — both are cheap and both extend the phone’s life by a year or two.

The OS question overrides the cost calculation. A perfectly repairable phone that no longer receives security updates is a phone that shouldn’t be used for banking. The lifespan figures already reflect this — a smartphone’s 3–5 year lifespan is driven more by update commitments than by battery or screen failure.

Fault-by-fault costs

Where the brand changes the answer

Apple and Google have the longest update commitments — around five to seven years on current models. Samsung’s flagship line is comparable. Budget Android devices often get two to three years, which makes a $200 screen repair on a three-year-old budget phone a poor bet: the screen may last two more years, but the software won’t.

Tablets follow the same logic with a longer hardware life and the same update constraints. An iPad at four years old is usually a repair; an Android tablet from the budget tier at four years old usually isn’t, because the update commitment has already expired.

Water damage is the category where repair usually loses. Even when the device works again after drying out, corrosion on the board causes intermittent faults for months afterwards. A water-damaged phone that’s been “fixed” is a phone that will fail again.

A worked example

A two-year-old iPhone, touch screen not working. The digitiser has failed. Installed quote $220.

Against an $900 comparable replacement: 24%. Lifespan used: roughly 40–50%. Repair. Both tests pass comfortably.

A three-year-old budget Android, cracked screen. Quote $180 against a $250 replacement: 72%. Bin — and the update question would have decided it anyway.

Games consoles

Typical lifespan: 6–8 years — though in practice a console lasts as long as its generation does, which is a different question entirely.

The decision repair: the board or the optical drive. Both sit at $150–$350 installed against a $300–$500 replacement, which is 30% to 117%.

What makes consoles different from every other device on this page is the generation question. A console doesn’t become less reliable when its generation ends — it becomes less useful. Online services get retired, new games stop releasing, and the machine’s future value drops faster than its hardware lifespan suggests. That means the lifespan rule should be applied against the console’s remaining generation, not against its mechanical expected life.

A five-year-old console with a board failure is at 60–80% of its mechanical life — but if its generation is two years from being replaced, the repair is buying far less than the numbers suggest.

Fault-by-fault costs

Where the brand changes the answer

The three major platforms have different failure profiles. PlayStation consoles are generally the most mechanically reliable, but the earlier generations had thermal paste and fan issues that appear around year four. Xbox consoles had a well-documented failure period around the 360 generation, and the more recent hardware is more reliable but runs hot under load. Nintendo Switch consoles are the most robust mechanically, but the Joy-Con drift is a design flaw rather than a wear item, and it appears on almost every unit eventually.

Nintendo’s first-party repair pricing is also notably cheaper than the other two platforms, which changes the calculation. A Switch repair at $80 is worth doing long past the point where the same fault on a PlayStation or Xbox would be a bin.

A worked example

A five-year-old console, overheating and shutting down. The thermal paste has degraded. Parts $10, installed quote $120.

Against a $400 comparable replacement: 30%. Lifespan used: roughly 60–70%. Repair — and this is one of the cheapest fixes on any console. Thermal paste degradation is the single most common console fault, and it’s the one people most often mistake for a terminal failure.

Monitors

Typical lifespan: 8–12 years. Longer than a TV, because a monitor runs at consistent brightness rather than being asked to perform HDR and peak-brightness work.

The decision repair: the panel, same as a TV — but because monitors are cheaper, the arithmetic is tighter. A $300 monitor with a $250 backlight failure is a bin; the same failure on a $900 monitor is a repair.

The category has one trap: monitors are often worth repairing for longer than their price suggests, because the replacement isn’t the monitor alone. A monitor at the right size, resolution, and colour accuracy for your setup is a specific thing, and a like-for-like replacement isn’t always the $200 budget option — it’s whatever the closest match to the original cost.

Fault-by-fault costs

Where the brand changes the answer

Professional and colour-accurate monitors are worth repairing far past their consumer equivalent. A calibrated graphics monitor at $800–$1,500 is a different calculation from a $200 office panel, and the repair economics reflect it.

Curved and ultrawide monitors introduce a specific problem: the panel is the most expensive component, the panels are less interchangeable, and the failure rate on early curved models was higher than on flat panels of the same era.

A worked example

A six-year-old monitor, no power. The power supply has failed. Part $40, installed quote $120.

Against a $350 comparable replacement: 34%. Lifespan used: roughly 50–75%. Repair — a power supply is the cheapest common fault on a monitor and passes the test on anything with years left.

Audio equipment

Typical lifespan: 4–8 years. Shorter than most of this page, because audio gear is battery-dependent and the battery is usually what ends its life.

The decision repair: the driver — the speaker itself — rather than the battery. This is the opposite of almost every other device on this page, and it’s worth understanding why.

Batteries in audio equipment are cheap and replaceable: $20–$60 for a Bluetooth speaker, $20–$50 for headphones. They pass the 50% test on almost any device worth owning. A failed driver, on the other hand, is often close to the cost of the device — a $40 driver in a $60 speaker is a bin, and the same $40 driver in a $250 speaker is a repair.

So audio follows the small-appliance pattern rather than the electronics pattern. The parts are cheap, the devices are cheap, and the decision turns almost entirely on what the device cost when new.

Fault-by-fault costs

Where the brand changes the answer

Premium audio brands — Bose, Sony, Sennheiser, Sonos — are worth repairing almost indefinitely, because the replacement cost is high and the parts are available. A $40 battery on a $300 speaker is an obvious repair at any age.

Budget audio is the opposite. A $30 Bluetooth speaker with a failed battery isn’t a repair decision — it’s a replacement decision that’s already made. Don’t spend $40 fixing a $25 device.

Headphones are the exception within the category. Wired headphones have no battery and no Bluetooth module, so the only faults are the cable, the jack, and the drivers. A cable repair at $30–$60 on a $250 pair of headphones is worth doing every time, and even a driver replacement is worth it on premium over-ear models.

A worked example

A two-year-old Bluetooth speaker, won’t hold a charge. The battery has failed. Part $25, installed quote $60.

Against a $200 comparable replacement: 30%. Lifespan used: roughly 30–50%. Repair. Both tests pass comfortably.

The same fault on a $60 speaker with a $50 quote: 83%. Bin.

The environmental consideration

Electronics are the category where the repair-or-replace decision matters most environmentally, and it’s worth being explicit about why.

E-waste is the fastest-growing waste stream in the world, and the majority of what’s discarded is repairable — the fault is usually one component, not the whole device. A phone binned over a battery, a laptop binned over a hinge, a TV binned over a backlight.

The embodied carbon in a new device is significant: manufacturing a smartphone accounts for around 80% of its lifetime carbon footprint, and the same is broadly true of laptops and TVs. Repairing rather than replacing avoids most of that, which means the environmental case and the financial case usually point the same way.

Where they diverge is the same place the financial case diverges — the panel. A failed screen is terminal financially and environmentally, because the panel is the device in carbon terms as much as in cost terms.

The practical implication is simple: the three-pattern structure on this page is also the environmental structure. Repair pattern 3 faults and you save money and carbon. Repair pattern 2 faults on newer devices and you save both. Replace pattern 1 faults, because there’s nothing to save.
