I looked at some past posts in this thread but didn't see anything directly related to my problem.
I have a WD65-838 that's about three years old with about 5250 hours on it. I decided to replace the bulb with this link on Newegg:
Says original Mitsubishi replacement lamp 915B441001 and comes with a Oscam bulb - actually sold by Ness Electronics which is AKA shopjimmy.
Received and replaced. It worked for about a minute or two then the screen started flickering in a green/cyan tone and make a clicking noise. Put the old bulb back in and the set works fine.
I called Ness and was told that this is a KNOWN
problem with this model and Oscam replacement bullbs. The color wheel detects a problem and goes nuts. Not sure it happens with every Oscam bulb but it happened to mine. Ness emailed a prepaid UPS return sticker for the item and is sending me a Phillips replacement bulb which they say should solve the problem. I'll have to wait and see.
Anyone else have this problem?
