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. Is that 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. I take it that was the color wheel?
What should I check? I dont know what the DMD board does but I see it's brought up alot with this fault.
If you have already replaced the lamp and ballast, to no avail, then it is time to take it in to a certified repair center. Most will charge a nominal diagnostic fee. My 61" did the same thing and it turned out to be the Light Engine (of which the DMD Board is a part).
If the problem were the color wheel, the lamp would come on for a bit until the color wheel sync couldn't be achieved and then it would turn off. The all-3-flashing-lights problem is the lamp. Here is a page from the service manual on the 3 blinking lights problem.
The Light Engine controls the ballast via a separate signal than the 320 Volts. The voltage reading means that the Power Board is working properly.
