RCA P60752EBLG1 Convergence Problem

I have a RCA P60752EBLG1 rear projection tv and on the sides and
top and bottom the screen bows like a arch and you can't see the
very end of the picture on both left and right, basically the picture
runs over and can't see a little bit of it. Also there is alot of blue.
when you look at words the blue extends beyond the words like
a blotch. I turned the blue driver down and focused it and is a
little better. Picture is fine to watck just want to fix the arches
onall 4 sides. Someone please point me in right direction. Thanks

SOURCE: philip tv has problems

If model number is 55pw9363 it sounds like you have a common problem in these sets--convergence.

If you go into the customer menu and select convergence and it is skewed and will not adjust the set needs the convergence circuit repaired.

I am attaching a couple of photos of sets with convergence trouble for you.

I also have Step by Step start to finish instructions for this repair in this model set--they tell you everything you will need and how to do it..If you are unable to do the repair---most shops are going to get 300 or more for this repair---you can buy almost all the parts you will need on EBAY for less than 30 dollars.

I have repaired hundreds of sets with convergence problems.

If the photos and the information helped you rate this solution as I do this here for free. If you want the instructions let me know and I can post them here for free.

Help with RCA projection TV P46812BL (chasis ptk195AA)


You have probably blown one of the convergence ICs. Effectively the easiest thing to do is replacing the whole convergence board, so that no soldering is involved.

Here you can buy a replacement convergence board, just select your model.

Let me know if you need further help.

Screen is bowed on top and bottom.


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

sounds like it is most likely the convergence power supply board, if it were just one color It would most likely be the convergence board itself
