You have either bad convergence ICs or just bad grounds on the IC. I would go ahead and replace the ICs and check those small ohm resistors, as you have to pull the signal board out anyway. For futher instructions see the website They may have what you are looking for. Be sure you have the TV model number next to you. Thanks for asking and show a few hands of support!

Convergance problem

Hi, I`m assuming your going into the menu and trying to adjust convergence and the lines won`t align? If so the convergence IC`s have failed and that circuit will need to be checked to see which parts have failed and then replace them, probably time to call in a tv tech for that one, video-tek

Intermittently screen move to one side with distrited picture

Might be the convergence chips. Do you have any problem moving the convergence under the menu setting? Convergence chips are reasonably priced. If you know a friend or someone who can solder better than average, I would go this route. My tv wasn't that bad; I wasn't able to set 2 of the 3 colors during convergence setup. Changing the 2 convergence chips did the trick!

Red green and blue lines on screen

It is common for the 24V supply to fail when the convergence ICs fail. There should be fuses somewhere in the area that should be checked. I don't have the manual for this model, but verify that all of the wires and connectors are attached.

52' take about 15 min. to come then only stay on for about 1hr

The convergence ICs overheat , you get bad picture and then the TV detects the fault and go in protection mode, that is the standby state.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • 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 note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
