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!

Re: RCA DLP/HDTV Vertical Lines

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!!

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!!

Vertical lines

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.
