Question about Samsung HLP4663W 46" Rear Projection HDTV
Lamp light flashed then tv restarts a few times then all 3 lights flash. No picture or sound.
I replaced the lamp with no success, then the ballast today. I stuck a voltmeter on the ballast power plug while it was plugged in and the tv powered on and it read 320 VDC so I assume the lamp, ballast and power supply are good. Would that be right?
I did notice about a month before it quit working a winding noise when the tv was powered off after running for several hours, more like half the day. That was probably the color wheel showing signs of normal wear and tear?
What should I check? I dont know what the DMD board does but I see it's brought up allot with this fault.
