Disconnect everything that plugs into the g-board, carefully uninstall the old board and reinstall the new board, plug in everything that was disconnected. Then turn the t.v. back on.

Even if you would find the parts, it's impossible to repair it - the multilayer board on which they are soldered is shorted and that cannot be fixed.

I have a sony kp57ws520. The set wont turn on and the lite blinks 9 times. I was told at one time to solder two specific diodes on the g-board and that worked for a period of time. Now the problem is back....


Resoldering those parts is known as a temporary "fix". Those parts need to be replaced. I believe that they are D616 and D6301. Both are on the "G" board. I don't have a listing for your specific model, but most of thr 57s are similar.

Keep us posted.

Sony vpl cx5 no voltage to lamp


I downloaded the schematics and drawings for $US9.00 and found what I thought may have been a thermistor turned out to be a fuse. Obtained one from Sony spares and it is now OK. If it is possible would you guys know the value of the fuse [amp/milliamps??] If you are familar it is fuse 2P connected to C board, it looks like a small lump of plastic or diode block. The cost of the fuse is outragous from Sony. I hope I do not have to replace it again. However, if I do I would love the valua and I could see if I could get one from Radio shack or someplace similar. If I was not retired I would buy one and put it on a step tranny and watch the ampmeter for the blow current. But, thats life when you decide to retire. I believe the voltage value is 3volts??

Would appreciate any feed-back on the value of the fuse.

And I hope this may help others

Thanks and Good-day
