Question about RCA HDLP50W151 50" Rear Projection HDTV

RCA DLP/HDTV Vertical Lines

We have owned RCA DLP HDTV model HD50LPW42 for almost 3 years. After the first year we had to replace the bulb. Since that first time, vertical lines appear on the screen and we have no idea how to get rid of them or where they come from. They appear then dissappear for a few minutes then reappear again for a longer period of time. It looks as though, sometimes, they try to go away, but no luck. We thought the bulb, lived through it, and the bulb went out. 2nd year...replaced bulb again, lines still appear. What do you think is causing this? Please help!

    Black vertical lines appear across the screen with a spacing of about one inch from line to line. The lines appear upon power-up and do not disappear the entire time the set is on. Other days the lines do not appear at all. The TV is the RCA Scenium HD50LPW42. I replaced the bulb about 2 months ago and I don't recall seeing the lines prior to that.

    Same problem, same TV (RCA Scenium). In addition, we are on our third lamp in four years. Now we have vertical lines come and go. We tried unplugging the TV for 5 minutes so the TV can "reboot." It takes about 30 minutes and the lines come back. They used to only appear about 5 minutes after the TV warmed up, they would stay on for about 5 minutes and then they would disappear for good. Now they come on and stay on 95% of the time. The lines are mostly white and green.

    I called RCA and they never heard of this problem and suggested that I call a local technician.

    Please help if you find a solution. This TV cost us $3,000 4 years ago and we should not be having this problem. Frustrated consumer DJB - 02/23/08.

This is djb1 who commented above on the vertical lines that have gotten progessively worse. I may have found a potential solution. I unplugged the TV, took the back door off where you replace the lamp, took the lamp out, changed our vacuum from a vacuum to a powerful blower and blew ALL visable dust off anywhere that I could. I paid special attention to the heavy dust that was on the TV blower fan blades and around the mirror. I also held the blower on the outside of the TV on the vents around the lamp door.

After I plugged the TV back in, the lines have disappeared. We watched TV last night for about 2 more hours and the vertical lines never came back. So far this morning, the lines have not come back and it has been a couple hours as well.

It's worth a try. The free solution may be as simple as clearing out all dust. LET'S HOPE IT'S A PERMANENT SOLUTION!!

    Djb1 here again. After 1-1/2 days, the vertical lines came back, but not nearly as bad so this time after unplugging the TV, I took the whole back off the TV and cleaned all the dust that I could see. So far, so good. This good be the solution. CLEAN THE DUST OUT OFF THE TV!! You'll be surprised of how much dust there is.



Rest your input source, if is a cable set top box power down and back on, if need be perform a manual rest on the cable box.    Michael

My rca dlp doesn't turn on

You probably need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

do you have a cordless phone placed nearby?
i just had that problem, and realised it was because of the phone's frequency (scary!). i move the phone/base away from the tv, and it's fine now.

I did some reading on this. They said its caused by a faulty DMD board. I understand it's costly... around $700 to replace. Still looking for a cheaper avenue...
