RCA 52" Mdl P52939, PTK195S16B

The unit turns on but there is a PO VO with a 1.15 on the screen. Repair guy said it is in service mode. Not sure how it go there and not sure how to get it off there. He also says (w/o charging me) that the memory made it go into service mode and it has now confused the TV. (HUH?). Told me to also get ready to pay $300-400 to fix it. The buttons on the front work, just the wrong one for the wrong item, i.e. volume up brings up menu, power and menu button do nothing, so on and so forth. Can anyone help me?! Bought TV second hand so not sure what to do with it.

But there are two
quick things you might be able to do. If it is a PTK195 you can most
likely install the updated power supply board. If you can solder and
know safety (like discharging caps) you can update the PS chip from an
STK730-??? to an STK730-180 (IIRC). I found that simply replacing the
chip with an equivalent fails most of the time. The 180s seem to hold
up.

Screen is blurry and when we took it apart the screen was bent.

Clean and vaccuum inside the TV, make sure it runs cool. Then replace the screen from RCA service?

Same problem as above, picture bowed top and bottom, convergence

Projection sets have two very common problems outlined below.

The first common problem is convergence

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. The TV can also shut down when the convergence starts to fail.

Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

I need the convergence code or how to get into the menu to converge my rca p52939 colours are not aligned

Hello,On your remote click the menu button and then go to the screen adjustment section. Once there chose convergence, and use the simple cross pattern to try to adjust your settings. If this does not work then you may have a convergence amplifier problem. For that you will have to have the convergence ICs replaced. I would suggest that you get a qualified TV repair man to do this for a fee. There are many instructions on how to do this on-line.I hope this helps,Regards,Shuttle83http://www.electron-age-technologies-llc.com

Rca p52939

Does the Tv pick up a signal ? ( picture/sound ) If not, you may have a tuner problem as the screen will default to blue with no signal apparent. Could also be a cable problem. Hope this helps

Please Help!

A chirping sound from a TV set is the switch mode power supply trying to start up, but gets shut down because of a major short inside the set or in one of the circuits.. Most likly in this set, the horizontal output transistor is shorted because of a defective flyback transformer. Thats whats the common problem is with this set. A repair like this, if this is the only parts that are bad, will run you about 300 to 400 bucks or so. In some cases, not many but a few times, I have seen poor solder connections on L401 cause the horizontal output transistor to go bad. There are no user replacable parts inside this set, so please play it safe and seek out a pro to assist you in this repair. Good luck PS Please do not forget to rate this thread.
