I recently wanted a new TV so looked at "faulty" ones on ebay. In a week or two I had:

- A 42" plasma (£70) with blown video inputs but VGA works fine, so I use that with a TV > VGA adapter I bought in HK and had laying around.

- A 32" HD LCD (£50) - described as "flashing red, green and blue" with no remote. I bought a replacement remote and pressed "menu" to get it out of burn-in mode.

- A 32" HD LCD (£40) - described as "green in the dark sections". Fixed by cleaning the LVDS connector.

I also have a 46" Bravia (KDL-46X3500) that has been dropped on one corner (damaging the bezel). The screen looks good but it's missing the UB1 board, I'm not sure if it's worth buying one because the screen might have been fatally damaged too.

Anyway Googling gets you a lot of info on TV faults, these sites are good:

http://www.tv.quuq.org/
http://www.eserviceinfo.com/
http://www.agoraquest.com/ - has lots of Sony stuff but the search function is crippled without a subs ($12).

fixya.com is appalling.

Service manual for that set is:
