I purchased a 52" Philips DLP TV this past summer and was told that all it needed was a new bulb. I bought the new bulb and put it in. I turned the set on and got a great picture but after about a minute, the picture goes out. I still have sound but no picture. After I cut it off and cut it back on, it does the same thing. Can you help me?

It is likely a bad fan that gets quiter as it warms up from use. There are two fans on that TV - one under the bulb housing and one at the left vent hole. They are special fans with three leads - +, - and an RPM indicator (yellow lead typically).
Don't know if this applys to you but if you have purchased anything but Osram or Philips replacement lamp for your DLP tv then this is probably your problem.. The generic is VERY tempting in this recession but in this case generic is poison to your dlp tv... i have a Mitsubishi 60735 and went thru 2 generic bulbs when my tv kept shutting down on it's own and the lights on front would flash, i could cut it back on for 10 minutes then flicker and shut down again ..well since the bulb was new i thought it may be defective so i got is exchanged for another one ... after all of the post i have seen how much repairs were going to cost on dlp sets no matter what the problem was ..i was ready to chunk the tv out the door when the second lamp was doing the same thing.....!! well a last ditch effort to save my tv before i trashed it or taking it apart to dissect it.. was to buy a brandname lamp ... in my case i purchased a Philips ..it cost twice as much =/ ..i could just return it if it didn't work.. well it was the generic lamps that was causing trouble.. the brandname worked perfectly .. i am just glad the generic lamp didn't do any damage to my TV!!! I have done further research on the generic lamps and realized that the damage it could have done was not worth the money i saved when i purchesed it... Generic is a great deal In some cases (household cleaners, etc..) but in this case GET THE NAME BRAND!!!! the only name brands i know of for these lamps are Philips or Osram/Sylvania.. hope this helps others from this headache. Do your research don't by generic lamp replacements, your DLP set cost to much to risk it.
I don't know of anyone who can donate a lamp, but I have done research and you can actually purchase a lamp off of ebay for $85.99 and then have the technician install it. Here is a link to the ebay site where the lamp is located.
The new bulb that went bad I purchased for less than $130.00 from http://www.Discount-Merchant.com/ . When I called them they immediatly sent me a new bulb free. Their number is 1-619-710-2637. A very good coumpany to do business with. They are also considering selling ballast for dlp TV's for around $200.00. The TV repair place that I have been going to told me that maybe the ballast made the bulb go out and it would cost between $600.00 and 800.00 to have them fix it. My TV is a Mitsubishi WD52725. dodger1
