A television breaks. The first instinct for many households is to start browsing for a replacement. But before you reach for your credit card, it's worth pausing — because repairs are often cheaper, faster and smarter than they appear from the outside. And sometimes, of course, they're not. The key is knowing the difference.
The 50% Rule — and Why It's a Starting Point, Not an Answer
The traditional consumer electronics guideline is simple: if the repair costs more than 50% of the replacement cost, replace. If it's under 50%, repair. It's a useful heuristic, but it leaves out several important variables — including the age of the television, the quality of what you'd be replacing it with, and whether the fault is likely to recur.
A television that's two years old with a repairable backlight fault is a very different situation from an eight-year-old set with a cracked panel. The maths look similar on paper but the logic is quite different.
What Common Repairs Actually Cost in the UK
| Fault Type | Typical Repair Cost | Typical Replacement Cost (Equivalent TV) |
|---|---|---|
| Backlight failure (LED strip) | £80–£150 | £400–£900 |
| Power supply board | £70–£130 | £400–£900 |
| Main board replacement | £100–£200 | £400–£900 |
| HDMI board / ports | £60–£120 | £400–£900 |
| Screen/panel crack | £200–£500+ | £400–£900 |
| Software/firmware issue | £40–£80 (diagnostic) | £400–£900 |
For most electronic component faults — power supply, backlight, main board — repair comfortably clears the 50% threshold. A cracked panel is the exception where replacement often makes more financial sense.
When Repair Is Clearly the Right Choice
Repair Makes Sense When:
- The television is less than 6 years old
- The fault is electronic (not a cracked screen)
- The repair cost is under 40% of replacement cost
- The set is a premium brand with good parts availability
- You're happy with the picture quality and features
- A warranty is offered on the repair work
Replacement Makes Sense When:
- The screen panel itself is cracked or broken
- The television is more than 8–10 years old
- Parts are unavailable or prohibitively expensive
- Multiple faults have developed in quick succession
- The repair cost exceeds 60% of replacement cost
- You want significantly improved features (4K, OLED, etc.)
The Environmental Argument
There is a third consideration that doesn't appear on a cost spreadsheet: electronic waste. A television contains rare earth metals, plastics and circuit boards that take decades to break down in landfill. Repairing a television that can be repaired — rather than discarding it — is one of the most effective things an individual household can do to reduce its electronics footprint.
"We throw away functioning televisions at an extraordinary rate. In most cases, what looks like a dead set to the owner looks like a forty-pound board replacement to an engineer. The environmental cost of disposing of it makes that repair case even stronger."
