Tv power light comes on, and the little green light one the pwer supply comes on but no sound or video what should i replace to get this working and help would be appreciated

Hello,
Yep. The power supply in Sanyo Plasmas are generally prone to failures. It could be a failure in the panel not priming, but I doubt it. Turn the lights off in the room, then try to turn it on. If you see the screen faintly flash, the panel is priming, but it is not coming on. If the screen is lit, but is still "black," then it is a control or digital board. If it is totally black with no light at all, then it doesn't entirely rule out the first two, but makes a power supply failure more likely.
They usually have a lot of heat damage to them. If you have tried unplugging it for 15 minutes, then plugging it back in and it still doesn't work, the it is most likely a secondary in the power supply.
I hope this helps you...

Found 1 of the 2 ac supply ( 8amp) fuses blown on the main pwr. supply. Replaced fuse and good so far. Looked over the ps for damaged components, none found. Checked current with ampmeter with tv on, showing 3amps. Cheers

this issue is related to either the y sustainer and z sustainer boards, checking the fuses on the y/b will giving you a good indication, if they are open(bad) then you'll have a easy fix, if not, i would try replacing the y board first.
