See attached photos and if set looks anything like this you have a convergence problem---set in customer menu has a way with the remote to attempt to adjust this--if will not adjust in some area of the screen parts in the convergence circuit need to be replaced--let me know what you find and I would be happy to give you advice.No two sets with this problem look exactly the same but these pictures should tell you if you have this problem or not.

DID anyone resolve thism problems??

What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related 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.

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 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 your need to fix it. See below for a fix

CONVERGENCE 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 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.

There can be several causes for this, few of which you can do anything about. However, a few things to try.

1) Replace the batteries on your remote control.
2) Try resetting the logic functions on your tv by unplugging it for a minute, then plugging it back in.
3) Try covering up the infra-red receptor on the front of your TV to see if you're getting unwanted signals from the receptor. taping a piece of foil over that area is perfect. If it doesn't stop after doing these two things you'll probably need to take it to a shop.
4) If this does stop it, then look for unexpected signal sources. Have you added a remote control extender? Added a new device to your audio-video system? Changed to a new remote?

Good luck with your problem...I hope you can work it out.

Hi


Thanks for using FixYa. Heat is the number one enemy of electronics, and these sets operate hot. This problem is caused by the power supply being overloaded. This is often caused by failed convergence ICs. I don’t think the issue is with the power supply of the unit as the sound is coming fine from the unit. This model of TV has over 3,000 parts which include millions of transistors inside the integrated circuits. Over time the capacitors will change value, leak and become defective. Resistors will change value and burn. This will cause other components to become defective. This can has a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. Please do accept the solution if the issue is resolved or else revert for further assistance.

How many times does the red light blink?
Do you still have audio?
Is the screen lighting up at all (such as a dark gray)?

Also let me know of anything else that may help me determine the cause.

thanks

Benjamin

this set don,t have a lamp it has 3crt red blue green.
what is the set doing i seen stk go bad stk 392-040
but look for bad solder on them.

I have the same tv.. Does the power light even try to come on? or do you hear clicking sounds? let me know maybe i can help u out

I am not sure what your looking tp purchase and replace. Can you be more specific.

depends on how good you are at soldering, you may consider sending the board into ptscorp.com

Here is the link just look under the section tittled convergence IC and you should find the STK numbers of the ICs you need. You will need two of them. Heres the link.

Red convergence IC defective===Replace Stk392-040 IC's.

Change both for reliability.I use Panasonic brand with no recalls.

let me know how it goes....T.

Blue should converge on top of "yellow".Bad connection(s)

on blue convergence IC.Replace both IC's for durable repair.

Check pico fuses.Reset convergence alignment.

Your convergence IC's are bad, possibly more parts, there is a convergence board that has most of the parts that fail, there was no power spike that did this, it is a common problem on CRT Projection TVs, especially HD Sets.
