Get your hands on a Mitsubishi remote, almost any made in last ten years will work.

Go into customer menu and select convergence, then advanced--if red or blue will not move in some direction the set needs the STK-392-570 CONVERGENCE CHIPS REPLACED--I GATHER YOU DID NOT GET A WARRANTY ON THE SET? AS IS?

I stumbled across a tutorial on fixing the convergence for my Sony KP-46WT510 a while ago, and now I can't find it again! Does anyone know where I can find that tutorial or one similar to it? We've been...

Here is a walk through on how to set your convergence.

A quick and easy way to try and let the TV realign the convergence try this...

1) Turn on the TV and tune to a channel and let it warm up for about a half an hour to let everything settle into its normal operating mode.

2) Press the Flash Focus button on the original TV remote. A cross pattern will show on the screen and the process is complete when the cross turns white and the TV returns to the program you were watching.

3) Do not press any other buttons until this process has completed.

If this does not adjust it enough you can adjust the convergence manually as follows:

1) Press the menu button on the original TV remote.

2) Use the arrow keys on the remote to highlight setup and press + button to select.

3) Use arrow keys to select convergence and press + button to select.

4) A pattern of white crosses appears, with a yellow [ ] around one of the
crosses. Aligned crosses (which do not need adjustment) look white and
have little or no red or blue showing. Crosses that are not aligned show
red or blue shades beyond their edges.

5) Use the arrow keys to move the [ ] to a cross that is not aligned. ***Note: start with crosses in the middle and work outward ****
*** TIP: Set the alignment while about 5 feet from TV for better results ****

6) Press the + button to select the cross and the [ ] will turn red indicating it is ready to adjust the Red convergence.

7) Use the arrow keys to move the red cross on top of the white one or at least as close as you can get it.

8) Once the Red is aligned press the + key again and the [ ] will turn blue. This indicates it is now ready to adjust the blue convergence.

9) Use the arrow keys to move the blue cross on top of the white one or at least as close as you can get it.

10) Once you have aligned the blue cross press the + button again and the [ ] should turn yellow.

11) Repeat steps 5 through 10 until all the crosses are aligned. To exit back to regular programming press the menu button on the remote.

52 inch has double vision like the red and gereen colorr are serperated.

the convergeance is off. some remotes allow you to tune this in the setup menu on your television. in most cases though this is something that has been caused by moving the television around or just plain ole time. if you cannot correct it using your remote and the normal menu on your tv then you will need to contact a repair technician in your area to schedule him/her to recalibrate your tv and repair the separating 3d looking issue that is common with convergeance.

Good Luck!

I've got an RCA ctc195 series TV and the lamps appear to be working but the TV images are coming on with blue/red/green around the edges making them blurry - I know it's an old TV but I need it to work...

It sounds as if you have a convergence issue. If you go into the menue with the remote control
and highlite the screen selection. this should get you to the convergence selection. if you highlite
the RED selection and use the arrow buttons on the remote, you should be able to move the RED
either vertically or horizonally over top of the green line. Do the same with the BLUE selection.
If they do not move, you probly have a failure with the Convergence power Supply. To my knowlege, that board is no longer available and you would need a professioal Service tech to repair the board.
Hope this helps,

Concave tv screen colors distorted just had tv repaired one year ago for same problem

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.


Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution


You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from

Can't get the blue and red box to align

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip 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.

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.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from that includes replacement coolant, photos. instructions, etc.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.

Red is out of convergence

I would stay away from that repair man. That model has just one Convergence IC number STK393-110 and it takes about 45 minutes from start to finish to remove the old IC and install the new one. You can get the replacement IC at the following link and they provide free instalation instructions with pictures so you can do the repair yourself for less than 30.00. Heres the link. You need just 1 STK393-110 Convergence IC they have free shipping as well.

Convergence without a remote

First off, you do need the original remote to adjust the convergence, Second, the service mode will not fix your problem. If the colors have all drifted, you have a problem in the convergence drive circuit. Most likely the convergence IC's are bad or going bad. The service menu is not a fix all for the problems with the convergence. The service mode will or can make minor convergence adjustments,not anything where all the colors are off. If you have no solid state repair experience, call out a service person to assist you in this repair. Good Luck

Pt-47wx49e service mode

It sounds like the convergence amplifier IC for the red crt is at fault. To check this, go into your user menu and pull up the red convergence. Try to move it up/down or side to side(it doesnt matter). If it moves up and down, then the vertical amp is working. Likewise if it moves side to side, then the horizontal part of the IC is working. If it dosen't move at all, or only moves up/down or side to side, then the IC is bad. There are 2 large IC's on the chassis, mounted to large heatsinks. They have STK392-110 or some variation of an STK392. If yow feel that the IC is bad, change the ic BEFORE you go into the service mode, as you wont need it if the ic is bad. To get into theservice mode: 1 make sure tv is in cable mode 2 set sleep timer to 30 minutes 3 tune to channel 124 4 use volume down on front of set to turn volume all the way down. ( writing will appear in the top left corner). 5 use remote control and press the power button. 6 the 7 button on the remote will put it convergence mode. Good Luck!
