Question about Projection Televisions
Remove diodes D2500 and D2501 (which are only protection, making the TV goes to standby instead of powering on) from the main power supply board. If the light does turn to a green one instead of going back to standby and you have the sound but no image, it should be the same problem as I had, which seems to be frequent with these Funai piece of junk.
You need to replace the ceramic capacitor C2258 on the main power supply board, it should be the faulty part as it was on mine. This capacitor is near an aluminium heatsink and was slightly burnt.
Here are the specs of that part from the service manual:
C2258 CAP CERAMIC HV 3300pF 2KV R K
As I didn't find a capacitor with these specs, I put two capacitors in parallel and it works fine now. Good luck!
