Modern televisions are complex—many “dead TV” issues are caused by a single failed component that can be repaired or replaced
without needing a whole new set. Below are the most common faults engineers diagnose and fix.
Pricing depends on TV size, panel type, parts availability, and whether the issue is a board-level repair or a full module replacement.
These ranges are a helpful starting point before inspection.
| Fault Type | Typical Repair Range | Common Cause |
|---|---|---|
| Fault diagnosis & inspection | £20 – £60 | Initial testing to confirm the failing part |
| Standby light but won’t turn on | £40 – £120 | Power supply / main board faults |
| No power (dead TV) | £50 – £150 | Power board / internal protection triggers |
| No picture but sound works | £60 – £180 | Backlight failure or board-level repair |
| Backlight repair / replacement | £60 – £150 | LED strip failure / diffusion issues |
| Vertical lines / half screen / flicker | £70 – £220 | T-Con, panel bonding, main board issues |
| HDMI port repair | £40 – £120 | Loose/damaged socket or solder joints |
| Software/firmware repair | £30 – £90 | Update failure, corruption, smart OS faults |
| Cracked screen assessment | £20 – £60 | Panel cost check and availability review |
Share what’s happening (for example “sound but no picture” or “TV won’t turn on”) and include the brand and screen size.
The more accurate the symptoms, the faster the diagnosis.
Engineers typically test the power supply, main board, backlight, T-Con board, and connectors to locate the root cause.
Many faults can be resolved with targeted component repair instead of replacing the entire TV.
Once repaired, the TV is tested for stability (power cycling, inputs, picture uniformity, and audio) to ensure it’s reliable for daily use.
Your model number helps confirm parts compatibility and improves quote accuracy. You can usually find it:
Repairs are often worthwhile when the fault is related to power, backlight, ports,
or board-level components. A damaged panel (cracked screen) is the most common case where repair may be uneconomical.

If repair isn’t economical (commonly due to a cracked panel or parts shortages), you can still recycle responsibly and recover value
from certain internal components.
Most common TV repairs fall within £40 – £180 depending on the fault, screen size, and parts availability.
An inspection confirms the exact issue and the best repair option.
Yes. This is often caused by a backlight failure or a board-level issue and is commonly repairable.
Cracked screens can sometimes be replaced, but the panel is usually the most expensive part. An assessment can confirm
whether a replacement is available and cost-effective for your model.
Many repairs are completed after diagnosis once parts are available. Time-frames depend on the fault type and whether components
need ordering.
Share the brand, screen size, model number, and a clear description of the symptoms
(e.g., “standby light on but won’t start”).
