Question about Televison & Video

I am seeing two of everything. I have tried to use the converge feature, but I cannot get everything to line up. It only allows you to go so far with the red and the blue. What should I do now?

Easy fix.
you need to replace the two convergence chips that are attached to the heat sink.
they are the two identical chips next to each other with a lot of legs on them.

My 52 inch RCA projection tv has a blue line around everything white


The convergence needs correction. If its not able to be cleared up by running the auto convergence feature in the setu menu then you will need to repair the convergence. You can get free technical assistance and parts foor your RCA at www.tvrepairworld.com they are RCA experts with that chassis

Replaced convergence ic's and picture is good but still no blue color to adjust in the convergence mode. the blue bulb is lit in back.


You may have pressed a wrong button when in service mode---it allows among other things to turn individual colors off like Blue--to make it easy to adjust red to green first.

Also take a look with set on into the Blue lens to make sure you have a image and it does not look like a blue flood light.

a last note: if you tampered with the lens (they have a wing nut on side that allows them to be turned you may have on the blue turned the lens so far there is no focus---for that lens--Did you?

Have you tried the auto converge or flash focus adjustment? This feature allows you to adjust the convergence automatically. If it doesn't work,convergence circuit is faulty. You need to replace the convergence kit, To do this you need some basics on electronics.

The tv is showing everything kind of double and everything is double lined in red and green


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Hi...

I would try the Convergence setup in the service menu ( IF they allow you to do that)

If the internal convergence isnt enough you might have to have the convergence amps replaced

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Most likely, this is a problem with the convergence board. The convergence amps (STK392-040 x 2)are internally shorted. These can be replaced or the whole convergence board can be replaced. It's cheaper to replace the amps, but more convienent to replace the board (especially for the less electronically inclined!! :) Hope this helps ...
