    i had this same problem, so we got a repair man to come out. while he was working on it he broke one of the rails connecting the two circuit boards together, and when he came back he said he fixed the rail. no we have no picture but we have sound. does anyone know if it might be the rails are not hooked up correctly because he used wires not a replacement rail. he has no idea now either.. hes a hack. does anyone know if it might be the rail is not hooked up right or what it could be?

It sounds like you convergence amplifiers are about to malfunction. If possible can you post a picture of what is happening. Again by the description you gave it sounds like the convergence amplifiers.

If you go to a shop the cost will about $400 - $500 (includes parts and labor).
If you do it yourself the cost will be about $25.00 - $50.00 (includes parts labor is free)

If you choose to do this yourself, here are the basic instructions:
1. Unplug the TV set
2. Take the rear bottom panel off
3. look for a large heat sink with two large black ICs (STK392-110) (6 sided components but rectangular in shape) on it, and remove the board the ICs are on from the TV set.
4. Unsolder the components using a soldering iron and a suction solder remover.
5. disconnect the components (ICs) from the heat sink
6. Unsolder all of the bias resistors and replace them with the proper values (usually 220, 150, 3.3, 2.2, and 3.9 ohms)
7. install the new ICs (STK392-110)
8. solder all connections IC and bias resistors
9. Inspect for shorts
10. reinstall circuit board
11. Plug the TV set in and turn it on.


I hope this helps

Thank you,

Hi! I am experiencing the following three


Hi Rafael,

First of all thank you for posting your question here at Fixya.
Please confirm if the brand and model number above is correct.
Blinking of the the LED (yellow and blue) at the front panel indicating that the lamp door cover is not seated properly. This cover will engaged to a micro switch giving the signal to the processor, once it is in open position, the unit will not power up and will experienced that kind of blinking error code. Go back to the lamp door cover and ensure that it is properly seat-in.
3D, 2D, red/green/blue ghost on the picture and letters means that the convergence circuitry gone bad. Symptoms is not connected to the light engine. The faulty parts is the convergence chips(IC). This chips are mounted on the large aluminum heat sink and starts with STKXXXX-XX (X means number). The most common STK chips used on Projection TV's is the STK392-110. You have to replaced them both on the board to resolve the issue(red ghosting). It is necessary also to check the resistance value of the resistors around its circuitry using the multimeter. For more info how to repair a convergence problem, watch the video below.

Red and blue ghosting,


The most likely cause is shorted convergence chips and possibly a few pico fuses.

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the 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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2
Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
