Convergence problem panasonic televison

Unless you are familiar with TV systems, this is best left to a professional. Rear projection systems typically use three separate image sources (red, green and blue) to display the picture. If any of these sources is misaligned, the convergence problem arises. It may be something as simple as a bump while transporting it or some loose screws but given the voltages in the back of TV systems, it is much safer to get a TV engineer to make the proper adjustments for you.

We cannot align the blue. The projectors appear

If the error is severe, this is a convergence problem. Convergence ICs are not too hard to change but require good soldering skills. There can be two or three ICS.
A service shop will charge $200 -$600 depending on service call, parts costs, labour, etc.
A slight error that just barely won't correct is an alignment issue. There are a lot of adjustments done by remote. Digital adjustments are not forgiving. Have a pro do the adjustment.

CRT Rear-Projection Red Vertical Alignment

You may have a convergence problem. Here are some of the most common symptoms and example photos.

  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

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


You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

51mp392h Blue Convergence Problem

Hello rogeuryder,

This is the one thing that even make TV repair persons shudder. You don't really have a convergence problem in the normal sense. The convergence works. What you have is a misaligned convergence situation which any documentation and or book on TV repair will tell you that at this point manual convergence adjustment is needed and the only thing you will have to do is keep trying to adjust the convergence until you get the center aligned, and then work towards the outer edges using both static (Center) and dynamic (outer edges) convergence techniques.

As this may sound it is; Very Very Tedious.

Here is something that may help you:,M1

I have used this book when I use to teach TV repair. I hope you discover what I am tried to convey in my e-mail, this is no longer a question of can you fix a TV? It has become a question of do you have the patience to adjust a TV.

Good fortune in doing this, you will succeed if you just take your time and do static convergence first and then do the dynamic convergence with the manual controls. The procedure will be in the service manual.

I hope this helps

Thank you,

Blue adjustment wont adjust

you will need to change the convergence IC. they are cheap so its better to change both at the same time as the red is sure to follow soon. Also check the resistors that power the ICs as usually one or two go open when the IC goes out.

Blue Non-Convergence

These sets quite often lose their memory and can be adjusted with remote control , but , MORE often I have to change the convergence amplifiers. There are two amps with 3 channels each for the up/down left/right for each colour . You did not say if the blue was curved with this displacement , if so AMP or fusible resister . If resister open I will change the amps as a pair. You will need to clean the old heatsink grease off(it will be baked on) and apply a fresh thin coat .

Sorry not for the faint of heart or lack of soldering/desoldering
experienced .
The remote control buttons change their functions when in convergence adjust mode . Let me know If you want the overlay and instructions to adjust.
