Tip & How-To about Samsung DLP HL-P4663W 46" Rear Projection HDTV-Ready Television

DLP -RPTV lamp/ballast Failures

All, One question or comment that I have never seen on the threads dealing with multiple failures of the DLP Lamp and ballast systems is what is the unit installed in? How far is the cabinet from the wall? The units I have looked at haved forced fan cooling to beep the lamp from self destructing. On the HLP4663W if the unit is placed against a wall the exhaust (heated) air port is blocked. Too close to the wall and the heated air is recirculated back into the cabinet directly over the ballast module. It is possible that the lamp/ballast assembly is running too hot. Not hot enough to trip the safety circuits but hot enough to degrade the life expectancy of the unit and drastically shorten the life of the lamp and/or ballast. IMHO if the cabinet is close to a radiator or within 6" of a wall thermal problems will result. Just my 2cents. Zenith451

i replaced my lamp and my lamp ballast in my dlp tv but i have a dark picture its samsung hl56a650


As long as you used the correct lamp and ballast, about the only thing left would be the light tunnel which is part of the light engine(optical block) which is very expensive to replace. Was it like this before the old lamp went out? the only time I've seen this at the shop, is when the wrong lamp was installed, but have read about a light tunnel failure as a possibility. This is kind of a long shot, but look at all of the electrolytic capacitors on the power supply module if you can get to it, and see if any of them are bulged or domed on top rather than flat. I have seen caps cause this with different brands, but never on a Samsung. It may be worth spending a few dollars to let a shop give you an estimate on it.

ballast or color wheel next?


The color wheel will normally spin-up even for a brief moment when the set is powered up. I have not seen a color wheel go out with a lamp. I have seen a ballast go bad with a lamp. I would replace the ballast first. You did not state wheather the color wheel was noisy or not. On the Samsung DLP, the color wheel is normally very noisy before it is gone. I hope this will help you.
