Question about RCA P52939 52" Rear Projection Television

1 Answer

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

RCA P52939 Chassis PTK195S16B

Was working fine for about 5 years, then all of a sudden fluctuates between top and bottom being bowed with a slight color discoloration.

Have researched it, believe it to be related to convergence, read somewhere that may usually be a convergence amplifier problem.

Debating now whether to try to fix it myself, or have someone else do it. Wonder how much it would be?

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

Have a p61927 rca 61" big screen - chassis ptk195m2 - picture bows in at top/bottom, color overlaps- thought it was stk730-130 on convergence board but don't see it, is it located on the back of board ?...


I believe that is on the back of the convergence board. What makes you suspect that particular switching regulator out of curiosity? It may very well be, but just wondering how you pinpointed it to that.

Thanks
Tim

Hi i have a RCA P52937SG with the bowing of the screen


The problem may still be on the power supply board (one of the supplies may be missing and) when you unplug the supply both supplies go missing check the supply voltages and repost

Bowed at top and bottom


No amount of cleaning is going to fix this problem, Go to menu look for setup see if you have convergences listed on menu if so try auto converge. If convergence is not on menu then you have a open fuse next flyback transfomer FL231 middle fuse.

Check Cr4503 in the vertical circuit for short or leaking. The convergence circuit is most likely fine. Also check for any leaky electrolytic caps in the 500 block. (example) CR4503 will be printed on the PCB as CR503. The vertical circuit is located in the center of the chassis behind the big aluminum heat sink.

I cannot adjust my convergence


This is a very common problem with the ITC222 chassis. If you cannot access the Convergence Menu (either in Customer or Service Menu), the FL231 fusible link is the culprit. More than likely that is blown, which will cause the Convergence Menu to disappear, "bowing" picture, convergence to be off, and will run as  "tube CRT" mode. 
It is also important to check the Flyback transformer and the solder connections below it. If you have a bad connection (i.e. cracked solder), FL231 will blow again and experience the same problems.

Picture bows on top and bottom of picture......


Your problem is the convergence IC'S. They have STK ###-### the # are numbers. You can get parts at http://partstore.com. If your not a tech and an experimenter or a handi person Pease be aware of the hi voltage inside these sets. Also be aware your going to need to unsolder and resolder the ICs in and from the printed circuit board. Good Luck
