Convergence and picture problems

In a APEX set change the convergence chips (2) AND use the original remote to adjust the set. There are several sites like TV parts.com that sell kits based on brand and model number.

The tv have a problems known as a convergence problems,it is dead.Tv have colors R,G,B lines mis alignments,have shadows pictures or 3D picture look alike?Yes the tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts,must be replace on the tv convergence board to solved the tv convergence picture problems.The shop will cost u like $300-350 for parts and labors.

hello, the convergence ic's have gone bad in your tv . and sometimes they fail because of a 50 mfd @ 50v capacitor by each ic goes bad. if you have the skill at soldiering and desoldiering you may try repairing it yourself otherwise leave it to a qualified repairman. thanks .....techman...580-243-8025

Here is your manual if all it is is adjustment. It most likely is the IC's that go bad that handle the convergence circuits. It is not hard usually, but you do need some electronic skills to get this done right. Brad

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

Sounds Like your convergence ICs big black ICs will part number on them example STK394-020 Call Mats for Parts on ICs 1-800-628-1118 Also Call Encompass you can order whole Board if you want to you just unplug old board and plug in new 1-800-638-3328

thecnical problem may be it a fuse on the main board or power supply.

Please have it taken care of ASAP. It definitely sounds like Cold Solder joints on the convergence IC's. Cheap repair now, if you stop playing it. Every-time the convergence goes out, the ic's struggle to bring it back in and can't and therefor over heat. so please have it taken care of Pronto. Apex used a Samsung chassis which was a good chassis in that PTV.

Hi
it is necessary to replace 2 convergence Ic's associated resistors test and repair power supply voltages , then performed a convergence alignment all of this could be around $ 120.00 in parts. go to www.vancebaldwin.com for parts

You rating to my answer is highly appreciate
.

Actually you have 3 problems. The two that you listed and the third which is: Apex does not support their units. Ask anyone who has tried to get any service. Your problem sounds like a bad digital convergence box. I fix this problem several times a week but on name brand sets. Cost is usually less than $100 for the part. Some problems with Apex equipment can be fixed if the part is a common off the shelf part. That is not the case with your problem. Apex equipment is cheap for a reason. All posts that I have read say that they do not last long and you can't get parts. That has also been my experience as a technician. We don't even accept Apex units for repair anymore. Next time spend the extra money to buy a name brand unit and it will more than likely be repairable.
