STK convergence ic replacement and instructions

WOW, I just read where you helped soneome with their TV and thought how awesome. Maybe you can help me! MyTV gives like a 3d affect with three different colors separated. Do you think you can tell me where to get the IC's and how to fix it? Is it difficult to fix? Thanks so much!

Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

Hi Dave


Thanks for using FixYa. If the issue is with the failed convergence (STK) ICs which needs to be replaced then, it’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs(STK ICs) which are located behind the black/gray heat sink and also check theresistors as if they are short the ICs might blow again after sometime. Please check this picture:

And yes you are right there are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

My samsung rear projection tv has a problem with its convergence ic. i think theres two ics , but how do i tell which ic need replacing??


Always replace both once your going to the trouble each IC is usually less than $30.
This link will help show you what's involved.
convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

I have a HCL473W with a 'concave' screen effect on 2 colors??


You don't need to replace the whole board, regardless of which board it may be mounted on. The STK IC convergence chips alone are all that need to be replaced. You can order them from a number of different online sites. You can try Alibaba.com. If you have any more questions, feel free to ask!

Fuzzy picture and dark picture and color seperation when hot.


The colors seperating is a convergence problem, as far as being dim this may be related but the TV likely needs service adjustments.

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.

Good Day, Bosjerry;

I believe the IC's are on the left of the TV, looking from back, the TV uses STK 392-040 (two) convergence IC's. They will be mounted on a large heat sink (large silver/metal) looking device.

Good Luck, big IRISH>

60PP9352 60 in. Rear - Blue convergence issue


Replacing only the ICs MAY solve the problem, however, many people have also had blown resistors requiring replacement. 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.
You do not have to replace any transistors to fix this convergence failure.
