Repair your TV.

A professional TV repair service can extend the life of your OLED, LED, or QLED set by years. In the UK, repairing electronics also helps reduce "e-waste," making it a more sustainable choice for the environmentally conscious homeowner.

What Does the Work Involve?

• Initial Diagnostics: Testing power supplies, HDMI ports, and internal tuners to pinpoint the exact source of the failure.
• Safety Preparation: Discharging high-voltage capacitors and using Anti-Static (ESD) equipment to protect sensitive internal circuitry.
• Component Replacement: Swapping out faulty boards, such as the Power Supply Unit (PSU), Main Board, or T-Con board.
• Backlight Repair: Carefully removing the LCD panel to replace failed LED strips, a common cause of "sound but no picture" issues.
• Firmware Updates: Reflashing or updating the TV’s operating system to resolve software loops or "smart" feature glitches.
• Panel Inspection: Assessing the screen for physical damage or "tab bond" failure to determine if a repair is economically viable.
• Final Testing: A "soak test" where the unit is left running for several hours to ensure the fault does not return under heat stress.

Typical Costs

The cost of TV repair is largely dictated by the price of replacement parts and the complexity of the disassembly. While minor board repairs are affordable, replacing a cracked screen (the panel) often exceeds the cost of a new television.

Note: Most standard board or backlight repairs fall between £120 and £350 total. If a quote for a screen replacement exceeds 70% of the TV's current market value, replacement is usually recommended.

How Long Does It Take?

• On-site Diagnostics: 30 to 60 minutes to identify the fault.
• Simple Board Swaps: 1 to 2 hours if the part is carried on the van.
• Backlight Replacement: 2 to 4 hours due to the delicate nature of panel removal.
• Parts Ordering: 3 to 7 working days if specific components need to be sourced from manufacturers.

DIY or Professional?

TV repair is not a recommended DIY project for most homeowners. Modern sets contain large capacitors that can hold a lethal electrical charge even after the device has been unplugged for several days.

Furthermore, internal components are extremely sensitive to static electricity; touching a board without a grounded wrist strap can fry the processor instantly. Professional technicians have the specialised suction tools required to lift large, fragile screens without cracking them—a risk that makes DIY backlight repair very high-stakes.

Choosing the Right Tradesperson

• Brand Specialism: Ask if they have specific experience with your brand (e.g., LG OLEDs or Samsung QLEDs), as internal architectures vary wildly.
• Insurance: Ensure they have Public Liability insurance, especially if they are removing a large TV from a wall mount.
• Warranty: Look for a minimum 3-6 month warranty on the specific parts replaced.
• Red Flags: Avoid "technicians" who give a firm price over the phone without seeing the fault, or those who cannot explain their diagnostic process.

3 Questions to Ask:

• "Do you use new OEM (Original Equipment Manufacturer) parts or refurbished boards?"
• "Is the diagnostic fee refundable if the TV is deemed beyond economical repair?"
• "Do you provide a written report of the work carried out for insurance purposes?"

UK Regulations

• WEEE Directive: All electronic waste must be disposed of according to the Waste Electrical and Electronic Equipment regulations.
• BS EN 62368-1: The UK safety standard for audio, video, and communication technology that technicians should adhere to.
• PAT Testing: While not always mandatory for domestic repairs, many professionals will perform a Portable Appliance Test after reassembly to ensure the set is electrically safe.

Common Problems

• The "Click of Death": A clicking sound when trying to turn the TV on usually indicates a failing power supply board or blown capacitors.
• Blue or Purple Tint: This is often caused by the phosphor coating on the LED backlights wearing out; it requires a full backlight strip replacement.
• Boot Loops: If the TV shows the logo and then restarts, it is typically a firmware corruption issue or a fault on the main logic board.
• Horizontal Lines: Often a sign of panel failure or a loose ribbon cable; if the panel itself is "delaminating," the TV is usually a write-off.
