Hello Folks, thanks in advance for any guidance you may be able to provide.
Moved 59" Samsung plasma that was working flawlessly to basement to make way for new TV. Didn't turn on for several days but when did got nothing. Standby LED was on and did react to On signal but no sound or picture. Here's what we got when doing some minor readings:
Nothing of any concern noticeable on any boards or capacitors.
Standby ~5.3V
PS_ON ~3.3V
PowerON ~3.3V and goes down to ~.2V
VS_ON 0V up to 3.3V but then quickly goes back down to 0V
Green LED on logic board light blinks roughly once every 5 seconds (versus norm of once every second or so)
VS ~5.8V (panel sticker indicates should be ~217V)
VA ~.04V (panel sticker indicates should be ~55V)
Disconnecting power connector to Y and X boards no change in VA and VS
VSCAN test point on Y main voltage not present
Ve on X board (Vb in my boards case) ~4.6V
Looked at various threads, Samsung PDP Test Video and Samsung Fast Track Troubleshooting Manual but nothing definitive so not sure what to do next before just ordering and replacing parts. Thinking since this TV is nearly 10 years old perhaps others may have come across this issue and had an idea what is at fault. Any thoughts? Thanks once again in advance.
