Television and Home Theater

Hey all. Just wandering if anyone knew  where i can find a replacement d board for my sony kp51ws520 at a reasonable price. please help and tell me this isnt expensive lol.. if it is i guess its got to be replaced. thanks guys

I have a 10 year old Mitsubishi WS-65313 that won't turn on. When plugged in, green power light is on (solid) but no picture/clicking/anything. No response or change to green light when power or any other button is pushed. Checked switches with ohm meter, all OK. Only way to get green light to turn off is to unplug. Any ideas what to check? Thanks.

Thanks to the forums and my prior electronic repair history, a co-worker has asked that I perform some magic on bringing back the picture on her 1 1/2 year old LCD tv. The picture will come on if I unplug everything (power & inputs) and replug it all back in after many tries. Come back a while later leaving everything plugged in and you get sound but no picture. I have not taken it apart to look for burnt picos or anything at this point. I have not found much info on this problem other than other models require replacing the tcon board. I have not found that for this sanyo model.
