    When the TV is on there is a blue picture/logo/word, green picture/logo/word, and a red picture/logo/word. Do I have the same problem and need a convergence chip? I tried adjusting the focus on the inside, but that didn't help.

The regulator will sometimes blow the fuse when it shorts. Hopefully the regulator will solve the problem if not you will need to trouble shoot the convergence board itself

Picture doubles and looks like 3d


Your TV most likely has a convergence failure. ( common problem )

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 are some photos of convergence problems.

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 will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

60" TV has an arc in the pic


Check the fuses 1007 & 1405. If they are blown in will cause an Arc.  

Note: If the screen shrinks/expands you may need a chip kit from www.repairkits.com

LG rear projection


Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website:  

http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=3229 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from www.TvRepairKits.com  

Hope this helps :)

Convergance chip


Thats the regulator chip for the convergence circuits thats the one youre most likely needing, as your chassis doesnt have convergence ICs. You can get that IC at the following link and they will provide free installation instructions and free on line tech support just in case you need assistance. Here is the link.

GE 46GW947 BOWED PIC


the manual is almost impossible to find. But that chassis usually only has 1 IC that powers the convergence. Usually a STK730-020 or simallar. post the number off the IC you see up front and I will cross reference it for you and post a link where you can get a replacement

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
