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.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

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. Power light will blink. 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. And you should be able to get the grid straight.

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 youconv problems with no pic has sound - 69189a5.pngix it. See below for a fix

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 are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

No audio on sanyo ds31520 after replacing vertical IC.


Replacing vertical output IC won't poise this type of problem. Check the voltages at the audio output section.

No picture or sound with a red flashing power light. Have replaced the convergence IC's but no change (do not have the chirpint sound). Removed main power board & green LED does not light up


On that model the conv IC is usually not the solution. I believe its the blown capacitor problem with is an easy fix. Check the site www.TvRepairKits.com for a repair kit.

Mitsubishi WS-65908 Error Code 24


If you have an ohm meter, check the resistance from F9A04 to ground, and then reverse the leads and check F9A05 to ground. These supply +24 and -24 to the convergence integrated circuits. The conv ic's may be bad. Also, code 24 usually indicates vertical deflection failure as well. One other check to make.....The pic tubes on this set may leak a few drops of coolant onto the boards. Look VERY carefully for liquid drops on the boards or a green and or white corrosion spot or two on the boards under the pic tubes-near the front of the chassis.

Change the STK 392 IC's on their heat sinks. Check for bad resistors in the area. Check for open pico fuses. That should fix it. Let me know if this helps.

sounds like some of the 3.9ohm 1 watt resistors are open some will get destroyed when the ICs go out and you can tell by looking at them they need to be checked with one side unsoderd and lifted from circuit

Sound like the vertical deflection circuit is defrctive. Check for cold solder around the vertical IC, Check the Diode and cap that supply power to the Vertical IC. If it still do not work, change out/ replace the virtical IC.
