Question about Televison & Video
Sounds like a bad logic board, you say you have checked the voltages? I assume you mean inside the unit on the logic controller? Most of the time the problem you describe is due to a bad power supply but since you mentioned about voltages the only real option left is a failed logic board.
If you are looking in the system look around and get the model number off the main board inside. I can check how available it is and whether or not it's worth repairing.
Also, I take it you are certain you are out of warranty?

(Green Power LED will go Green the Go Off) Brief rise then collapse of the Vs and Va voltages.
This indicates a "Load" on the line.
Pull the CN-64 connector feeding Vs/Va voltages to the X-SUS.
Take an ohmage reading from the Va and Vs lines on each PWB.
This means you have to read the Connector on the Power Supply and the pulled connector going to the X-SUS.
See if there is a low value. Low value indicates a defective PWB.
Normal reading should be infinity. (Using the diode mode on the DV/Voltmeter, there will be a brief charge
time, then infinity.) In other words, it may appear as a low ohm reading, but should rise to infinity or open.
(Also not, if there is a charge on the line, the meter may show a low. You must Pull the CN68 connector and take
a reading again).
The line should now be infinity when reading the Power supply pins for Va and Vs and when reading the
connector going to the X-SUS PWB.)
If a Low is see on the connector, pull the CN32 Connector. (Bottom right hand plug on the Y-SUS PWB)
