GE Rear Projection TV Color Alignment

We have a major problem with our TV! Some days it shoes more blue than the rest, some days more red then the rest. But everyday its blurry as all get up! We have tried the converence thing in the front settings of the TV. But that doesnt help no matter how we align the lines. We have opened the back to find a 6 screw panel on the right which works great at some time but eventually goes back to what it was, sometimes the very next time we turn the TV on again. We also recently found a 10 oxegon shaped screw panel which we just started to mess with even though there is no labels to it. All I can tell is one of them will adjust the vertical alignment of the screen. Now what is wrong with our TV & how can we fix this on our own! We arent in any shape to buy a new TV & we are willing to do it ourselves if we can! Before we lose our eyesight trying to watch TV!

SOURCE: Out of alignment

You have a problem on the convergence power supply board. The microprocessor in your set thinks it is a direct view set. This is usually caused by the regulator IC on the convergence power supply board. The type number is STK730-130 if I remember correctly.

It is possible, that the type of connection you have to your TV are crossed.

With COMPONENT cables, you have 3 plugs, red green and blue.

If this is the case, correct the plugs location to the correct plug.

Lens alignment results in a fuzzy (diffused) picture.

outside of that I too am at a loss.

good luck and don't forget to vote!!!

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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 projection 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 pics of convergence problems.

Common 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.

Sounds like possible solder connections on the convergence ICs. If so, you will see the red, green, and blue not lining up on ever input and even the mits menu. If you can bump it to correct, its just a solder connection, but if its out all the time then the ICs need replaced. This is a difficult repair only recommended for skilled technicians (40 solder connections + possible re-alignment needed)

All color guns out of alignment


Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.

It sounds to me like the convergence amps themselves have failed. Ic7001 and Ic7002, both are STK392-110 Sanyo built Ic's and not an expensive job for a qualified shop. When shopping around for a shop to repair it ask what they charge for replacement of the convergence amps in this unit. And take the unit to them to save pickup and delivery charges...
Have a great day!
