TV repair help..??.

I have a Sony KDL-40S2000 that stays in standby and just blinks the standby light 4 times. This is likely a backlight inverter issue from what I can tell from looking online.

I think I'm looking for this part:
Part Number PCB2676 A06-126268 G
Alternate Part Number PCB2677 A06-126269 G


anyone have a hook up on parts?

I'm a Sony authorized servicer(out here in Abilene). Those don't look like Sony part #s, I can look up the part number/price next time I'm in the office. Some models have one inverter board, some have two. I can also check for bulletins on their site also.

4x does indicate a backlight error. A backlight error is normally caused by 1 of 3 things: a bad inverter(most common), no power to the inverter(bad power supply), or bad backlights(bad panel - most expensive).

There is a bulletin for the 4x blink code. The symptom given was only half of the screen was lit and replacing the inverter fixed it.

There is also a service tip about some connectors not being plugged in all the way and they had to redress the wires to get the unit to work. Normally a problem like this shows up pretty quick.

Note the prices listed are the retail prices given from the Sony Site. You shouldn't pay more than that for those parts. There isn't really a lot of markup from the dealer cost to retail, so making a deal is tough to do.

If you were feeling froggy and wanted to drive to Abilene, I could sell the parts at cost, but it wouldn't save you enough to cover gas.

thanks man.... I wonder if I should take the leap and try this or what.. I'd hate to spend 150ish bucks and find out that wasn't the issue and it ended up being the back light panel
