Question about RCA HD50LPW42 50" Rear Projection HDTV

1 Answer

TV turns itself off and then back on when I watch HD

I have an RCA 50" DLPHDTV. I had some issues with the lamp so I replaced that and I also had an issue with the video board and had that replaced as well.  Ever since I got the tv back it's very picky with what HD programming it lets me watch.  Mostly on sporting events or while playing video games in HD the tv will shut itself off and then after about 30 seconds it turns itself back on.  Any ideas??

Re: TV turns itself off and then back on when I watch HD

If it played OK before you replaced the video board and now you have an intermittent problem Suspect the part that was replaced...Does this set have a video board? I can't find one on my parts list. Also there are a lot of ISSUES with aftermarket lamps not working properly on hi bright pictures. I can find out correct part #'s with complete model #.

Tv turns off

Its the lamp that needs replacing. It will run for a couple of seconds and then it would dim or turn off.

Tv turns itself off after a few moments of clear viewing

HLP, HCN HL-S The Start-up Problem or/and
3 LEDs in the front blinking.

Unplug the set, pull out the lamp module (not all the way - leave it on the track) and push it back in.

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues

good luck
please mark the post with a fixya!

RCA HDLP50W151 keeps turning off

I had a set with a similar issue--at first the tv would suddenly turn itself off, sit for a moment while flashing the power button, then "reset" itself and continue running.

Then one day it quit starting up all together. I couldn't get a picture at all. I was hoping it just needed a new lamp (which is what I was able to gather from reading various troubleshooting forums).

I took it to a repair shop for a definitive opinion, and when they took a look at the TV it actually started smoking and the issue was definately the light engine, not the lamp.  Unfortunately, a light engine repair costs around $950.  If you try to do it yourself, the part costs about $700, if it is in stock (and it turns out that it often is NOT in stock).

Instead of putting that much money into this TV, I'm going to have to bite the bullet and get a new TV.  It just doesn't seem a good use of nearly a grand when new HDTVs can be had for around $1300.  Sorry for bad news.

If you can, try to replace the light first. You can get just the lamp for less than $200, although it may be a larger issue like mine.
