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 directiSAME TV(mitsubishi HD1080 series)-- corners of scr - 0667c5f.pngnvergence 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.

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Pt-47wx49e convergence problem


I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

Horizontal Curvature with convergence problem


DA, convergence circuit has failed, the IC`s and possibly a couple of support resistors need to be replaced, your right about it being a good set, 6 years is about average for convergence IC`s, call your local shops for a few estimates and get it fixed, it will run for a lot longer than 6 years, hope this is the advice your looking for, e-mail me if you have more questions, BMW Rider

Converge problem


Sounds like convergence issue--replace Stk IC's mounted

on large heat sinks. Check power supply for open fuse device.

Re-check convergence alignment.

WS-55809 - Video pinched in center, distorted, yellow/blue/red glow


This doesn't sound like a programming issue. I had a very similar problem about 6 months ago and I fixed problem. I had cold solder joint on the video power board. It was the board in the middle. The power supply was to the right. The video board had a driver with a bunch of legs. About 7 solder joint where cold or loose. I solder the board and my mitsu wide screen was fixed. Hope this helps.
