Fixes & Costs
- No power (65″ and less)
- These problems are often solved by finding problem components on the power board, or replacing the power board entirely. Common failures are due to faulty capacitors and transistors due to aging or power surges. The power input protection fuse usually fails too.
- Labor cost: usually ranges from $25 (inspection only) up to $65.
- Parts cost: individual components are typically less than $15 (including shipping), though new boards can vary significantly ($50 – $400). Additional labor and purchases are made after initial diagnosis and customer’s approval.
- Size limitation: I don’t work on TVs larger than 65″ (diagonal) due to TV weight and size.
LCD TV won’t turn on: faulty power board
Fix: replace faulty caps, shorted transistors, & fuse
- Sound and power, but no picture (55″ and less)
- Often, LCD backlights burn out while the rest of the TV works fine. Backlights are salvaged from broken TVs and usually resold on TV repair websites and eBay.
- Backlight test: with the TV on, shine a flashlight very close to the screen (within 2″) and look for an image.
- Backlights replacement labor cost:
- 40″ and less: $30
- greater than 40″: $35
- Note: not all backlight problems are due to burned out LEDs
- Parts cost: the average price for these are $25 plus tax and shipping.
- Size limitation: I don’t replace backlights on TVs larger than 55″ (diagonal) due to difficulty moving the fragile glass LCD.
- Often, LCD backlights burn out while the rest of the TV works fine. Backlights are salvaged from broken TVs and usually resold on TV repair websites and eBay.
Faulty backlights -> remove LCD glass from main assembly
Remove diffuser & prism layers, then swap out backlights
Reassemble and verify functionality
Transport
Currently, I don’t do house calls for TVs. Customers need to bring the TV to the shop for repair.
