Question about RCA D52W19 52" Rear Projection Television

Green lamp goes out within minutes of turning on tv

I have an RCA 52" Model, D52W20 about 4 years old, 2 weeks ago the green lamp went out and lights up only momentarily upon putting on the tv. I need some help in how to remove and replace this lamp if possible or perhaps there's something loose? Any advice or guidance would be greatly appreciated.

Check CRT board the Video IC on it can be bad so you do not have to replace Tube be Very carefull when you remove CRT board from Neck of Green Tube so you do not Breck it. Check all 3 tubes make sure none of them are leaking out coolent fluid.

Mitsubishi DLP overheating


Mitsubishi has problems with the thermal sensor going bad. They extended the warranty for several sets. The sensor is right by the lamp. Call mitsubishi and insist they do something for you. If you keep playing your set, the bulb could also be at risk. I would think your set is covered being a 62" set. Good-luck and be sure to act ASAP.

My rca 52 inch hdtv turns itself off after a few minutes


Sounds like the green tube shorting intermittantly. Have a qualified tech use a tube restorer to check for shorts, or the loss of the 300v line to the green tube.

RCA 52in HDTV will not stay on


I would turn the circuit board over and check for clod solder joints and cracked solder, you will have to look close, my other sugestion would be to get a can of freeze and spay the different IC's and see if it stays on longer.

Mitsubishi WD-52327 52 in. Rear Projection DLP


I have a 2 year old Mitsubishi Rear Projection 52" model WD-52525. I recently experienced the same problem as you. My TV quit without any warning and the red lamp light came on. I bought a replacement lamp just like you did, did everything you did too, but it still didn't work either. Since it's past the 1 yr warranty (of course), I took it in to an authorized service center for an estimate. They determined the light engine failed and it will cost me $816.35 to repair. I already shelled out $240+ for a lamp, $48 for the repair estimate and I said "hell" no, I'm not going to fix it for another $800+ and bought a new TV. I'm writing a letter to Mitsubishi expressing my deep dissatisfaction (to put it mildly) with this faulty product and will be requesting reimbursement, which I probably won't get. I sincerely hope this is not the same problem your TV has, but if it is be prepared for a costly fix.

the problem may be due to dry soldering in the power supply stage if it was with the lamp there would be red or green light showing the presence of the power to the tv after making it own some of the components get hot and it will make the the soldering point conectionless and after some time the heat sink get cooled and the soldering point gets connected and u will see the picture again it is a simple problem if u have a soldering iron u make it hot and re solder all the components in the first part of the circuit board and the problem if rectified
