RCA 52" TV Shuts off.

I have a 52" RCA rear projection TV. When I power it up, it immediately shuts off. Then a few seconds later,it tries again. Several years ago, it did this, and a repair service came out and fixed it in about 5 minutes, so it must be a common problem. I don't have the money to pay a repairman (about $350 five or six years ago) so I was hoping I could get some help here and fix it myself. I do have meters and a bit of knowledge, but NO big screen experience. I have also seen this problem on other posts, but I haven't seen any repair ideas. The model number is P52771AT, chassis number PTK178L2B. Thanks in advance for all help! Steve

Search the newsgroups. IIRC, a burned out lamp will do this.

What lamp!!??? Before you start looking for burned out, frikken light bulbs, try changing the high voltage splitter, 205064. If that doesn't fix it, either toss it or pay another tech to fix it. There are pages and pages of shutdown fixes for that chassis and people alot smarter than you and me have had their asses handed to them trying to isolate that fail, since it can be caused in so many areas.

Well said. That chassis is a particular PITA.

IME everything branded RCA is these days. I have this picture in my head of two guys in a Chinese factory. One says, "Damn, this model is a POS". The other says, "Don't worry, we'll rent the RCA label and the Yanks will still buy it".

Thanks! I will try the HiV splitter, and if that doesn't work, I'll go buy a plasma and junk this thing. It's a shame though...beautiful TV, and it says made in USA (not China) on the back, too. Steve

You don't have to buy the dammed splitter just to find out if it is bad. Yank the red wire from the flyback to the splitter and leave it hanging in the air.

DO NOT LET IT TOUCH ANYTHING OR COME NEAR ANYTHING. AT LEAST 3 INCHES BETWEEN IT AND ANYTHING ELSE! TWENTY SEVEN THOUSAND VOLTS AND IT HURTS LIKE HELL!

Now fire up the set. If it does not shut down, okay, then your splitter is probably bad. This is a lot better than buying a splitter just to find out.
