The only way to fix this red lines is to replace the convergence ICs.
The ICs part markings are STK392-110, located just under the CRT's mounted on heatsinks, you will see them as soon you open the back cover.
If you have basic hand soldering skills, this is something you could do yourself.
I fixed one TV today with the same failure and same model.
Let me know if you need more assistance.

Red color convergence issue; Red lines are curved


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Text/images overlap each other in 3 colors, 3D distorted picture


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 www.TvRepairKits.com. 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.

Rainbow lines in my projection tv


You have convergence problems. The convergence IC's that line up the red, green and blue crt's are bad. They will need to be replaced. Suggest a qualified tech do the work due to the complexity and alignments afterward

One of the convergence output IC's has stopped working and needs to be replaced. If the IC shorts out then it will draw too much current and possibly blow a fuse, and the set will shut down to protect itself. The IC should be replaced and the set realigned by someone with experience in convergence circuits.
