We need our Sony 52W4100 Bravia screen replaced. What is the cost?

If the screen is scratched it will need to be replaced, so yes it can be fixed but it will be expensive. If you have nothing to lose you could try reducing the effect of the scratches by polishing across them gently with fine jewellers rouge, try a corner first as it might completely ruin the screen. Not too much pressure as you will damage screen further

It will cost around 2/3rd of the total cost of the TV.

Sounds like a power board reset switch gone bad. Have the power board replaced.

If the problem is same with different input devices and you have ensured there are no loose contacts in power outlet, RC jack, cable and sockets, the TV needs servicing.

You have a defective panel. The only fix is to replace the panel. This would not be cost effective. Cheaper to buy a new TV.

This is a common problem for Sony BRAVIA KDL-52W4100. You can reconnect the LVDS cable to the Main board, the location # is CN4701.

Not fixable,because the LCD screen is limited produced.Cost the same to replaced LCD screen as to buy a new tv.When LCD screen is broken or crack is only now only use for salvage eclectronics parts that it.

The part number for the panel is: 1-802-593-11

The total cost is: $6,571.45 with a core return of $4,480 with a net cost of: $2091.45

This means that you pay $6,571.45 and the $4,480 will be refunded upon receipt of the damaged panel.

It is the LCD Panel causing the problem. If the unit is out of warranty, it would be too costly to replace. If it is in warranty, you can call 1800-222-SONY and they could help you find a service to repair it.

Yes but not cheaply
