Question about Televison & Video

Hi Ladywin, I have question regarding your fix on convergence problem pasted below: Is the reason to replace STK***-110 to STK***-120 or 150s, is because theyare more durable? "Start out with replacing both of your STK ICs 392-110s use 120s or the 150s Mats Electronics has them 1-800-628-1118 They are big black ICs and will have the part number on them STK392-110."

There is a blue shadow to the picture. The color chips were recently replaced and it has been doing this since the replacement. I have tried to adjust the convergence but on the screen with the cross hairs...


STK ICs that were replaced maybe the reason convergence is not lining up or you may have some open low ohm resistors that need to be replaced ,near convergence ICs. STK392-570.
Mats Electronics has STKs for 14.95 each

How To Fix A Convergence Problem


Here are some of the most common symptoms and example photos of a convergence problem.

This is a very common failure on Projection TV sets.


  • 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.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings 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.

If you can't move them in all directions 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 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 know what you are doing or you can call in a pro.

If you want to do the repair yourself check the site www.TvRepairKits.com

Their kits include a step by step photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Color will not match up


if your talking about the sets convergence does not line up and it looks like a 3-D picture than The best advice I can tell you at this point is to go to tvrepairkits.com and order the complete convergence kit for your model of TV set, no need to search and order multiple parts from different sources and pay multiple shipping fees! Go to http://www.tvrepairkits.com/xcart/home.php?partner=larry
The kit comes with original Sanyo STK IC'S , not those cheap aftermarket or china made IC'S full pictorial directions, the thermal paste, resistors, the correct Pico fuses, AND free live on-Line tech assistance in case you run into a problem with the repair. They ship out 2 to 3 day Priority mail, the next day in most cases GOOD LUCK!!!

How do I fix a converence problem?


Hi.


First try using Autofocus. If there is a convergence problem this won't fix the problem.

Try using the convergence alignment procedure from service manual.

Here the procedure that works on most Hitachi rear projection.

Here the grid with convergence problem

7f474c1.jpg


If the procedure does not work, then the two STK392-110 on convergence board must be replaced.

Before replacing the ICs you can test the pico fuses located on convergence boards. Simply read ohms to test if they have continuity.

Better also testing components on convergence board like resistors located at the base of STKs.

After removing the old STK, the new ones must be re-soldered using cooling paste.

Price for single IC can is about $8/$20. I think
STK392-110 on this model can be better replaced with STK392-150. I suggest contacting the seller on this.

The service manual is available here.

I have alot of offset blue and yellow in my picture. I tried convergence from the front but it didn't help...what can I do to fix w/o alot of cost in these tough times..?


Hi,
This problem is related to the convergence, but it requires replacement of IC STK from one of them who control convergence, check both and replace faulty IC STK from new one and your tv work fine again. You can buy the convergence IC's from the link click here.
Thanks for using fixya.
