Question about RCA P52930BL 52" Rear Projection Television

2 Answers

Screen went black, no picture

RCA Projection TV, Model # P46770CK; Service # P46770CKLG1. We were in the middle of watching tv and the screen just went black. There is still sound, but no picture so I'm guessing it's the picture lamp. The TV is 13 years old and we have never had any problems with it and I don't want to spend a lot of money fixing it, nor do I want to purchase a new tv right after all the money I just spent during the holidays. If it sounds like the picture lamp do you know if it's easy to fix? My husband loves to fix electronics, do you know where I would purchase a part for it? Is it worth fixing? Any help would be appreciated. Thanks, Michele

Re: Screen went black, no picture

A clue to what is wrong is by looking from the back (taking the back off) and looking to see if the three picture tubes have any yellow glow at the bottom of them where the three identical boards are located on each tube.. If you have no glow there you possibly have a resistor R4703 open. It is a 3.3 ohm resistor and feeds the voltage to the filaments in each tube where the glow is suppose to be. If you do have the glow the problem could be much more complicated. Another to check is to see if the menu comes up on the screen. You could possibly be in the wrong input mode, Check your input mode with the input button on the remote The number R4703 is a location number to identify where the resistor is. This is all I can tell you that would not require much more complicated procedures requiring a tv repairman to look at it. If you have an ohm meter you can check R4703 but it must be checked out of circuit. (or at least one leg loose) Hope this helps

RCA 62" mod p46770ck need

Now I know the rest of the story: After I went to see the TV I was told it had happened after a storm the next day the set was dead. She had already recieved the insurance money. She said she did not want to spend much money on it as she obtained the set at a garage sale for 60 bucks 6 years ago. As I looked into the circuit board I noticed evidence of water damage and looking up the case and on top, yup, thats why she got it so cheap. I do think it is lightly damaged. As a grandmother of a close friend I didn't Intend to charge her but she gave me some bucks and the insides of the tv. I'm sure their isn't much time on it. If any one wants some parts on a 1993 RCA mod p46770ck (48" screen) contact me thru snailmail @ Whiskers, rr1bx57a zip 64632 Include your ph.# and I will call you.

RCA Projection TV will not turn on

I just fix my RCA p46770ck with that faint click sound when you try to power on. It was the HV splitter for $74.and change. after a long hunt to find the source of the problem I did what my local appliance store said to do replace the hole board for $275 luckily I was able to return that because it did nothing different than my board/module click.... click.... clickclickclickclickclick turn on you peace of @#%! any way if you unscrew the back cover off you'll see a black box at the top left corner with 4 red wires going to it groped 3 and 1. The 1 is your HV (High Voltage) supply and then gets split to each tube. Oh you should of unplug the tv before you touch any thing HV is 30,000 volts after you unplug you should push the power button to get ride of all voltage. please feel free to contact me at for any Q: I can get part numbers or help in any whey i can

You have bad convergence IC's.. If your not experienced in troubleshooting electronics or soldering, you should have a trained tech take a gander at the set. Its not worth risking life and limb to save a few bucks, Good Luck
