Do you hear any noises while it attempts to power on? Clicks, pops, buzzes, whirrrs?
Are there any solid or flashing indicator lights on the front of the set?
Solid Red, which is normal. When I press power button on remote, or on the set itself - the light blinks twice, then goes back to solid.
Are you able to bring up the On-Board settings menu?
In a dark room - Does the screen "GLOW" black - or is it just "dead"?
There appears to be a very dull "flash" then just "dead".
I have an radio communications background. But I currently don't have any tools easily accessible (voltmeter) and such.
