Convergence output IC's

Where are the convergence output IC's and where can I get the new ones to replace them.Or, can I purchase a new board with the new IC's? Also, If I was to have a tech fix it who would be that person? Sears or Circuit city or something? Do you have any idea what it would cost?

Where are the convergence output IC's. I have the replacement parts at home but I can't find where to install them because the old ones were removed.

Does anyone have a picture diagram?

Thanks,
Javier

Colored lines at top and bottom when tv comes on and seeing double vision in different colors at all times


If your tv is not a DLP the problem is in the convergence, try to adjust it using your original remote control go to the setting menu then to the convergence section. Adjust the red and blue convergence. you should move the red and the blue in up, down and left, right if this color does not move far enough your convergence IC is already defective. Replacing this convergence IC will solve the problem. In locating this convergence IC you should remove the back cover of your unit but be sure to unplug it before doing this. This convergence IC is attached to a large aluminum plate, it is the heat sink, and it has a marking of stk- ### followed by numbers. You can try to pull it out using a soldering iron and soldering pump but be careful you may damage the board and cause much problem to your unit. Or you can contact a technician to do it for you and save you from stress good day and best regards.

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.

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 philips 9p6044. where can I buy convergence ic's and a


its far more likely that you need a new Vertical output IC. The convergence ICs wouldnt prevent the picture. When you have audio but no video it is often meaning vertical failure. Try replaceing the vertical IC

I cannot adjust the convergence.


You have convergence output failure. The output ICs will need to be replaced and possibly a small component like a resistor or two as well. Expect to pay a service company $350-$450 to resolve this.

Toshiba 40who8b convergeance problem


Good Day, harri1234;
Sounds like a convergence problem.
Convergence Output IC Failure
Corrective Action: Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version.
Good Luck, Big Irish.

Samsung HCN4226 Convergence IC Problem.


The problem is likely to be the digital convergence board that generates the convergence signal that is amplified by the output ICs.

How do you install the convergence part on a Mitsubishi WS55511 big screen tv? The part has prongs on the bottom but I don't know how to attach it.


you must de-solder the output IC first. Then I would suggest that you remove the heat sink by removing the philips screws holding it to the pc board. you will find white heat sink compound on the bottom of the heat sink. clean this off and remove the output IC. put some heat sink compound on the new IC and install in in the holes on the pc board. be careful removing the solder on the pc board. I like to use solder wick. Install the new IC and solder it up as the old one was. remember to check the convergence in both analog and digital, as you have to converge both for it to remember the settings. Hope this helps.

Colors all messed up


The fact that you used the term "magic focus" tells me you have a Hitachi projection set. When the colors no longer line up on a Hitachi projection TV, it means that most likely one of the convergence output IC's has shorted out. Sometimes a shorted convergence output IC will burn up a low value resistor too. I have also seen a convergence IC crack loose from the board and burn up 3 low-value resistors. If your set is using the STK392-110 IC's, it is probably a good idea to go ahead and replace both IC's with the newer upgraded STK392-150 IC's. The output IC's should be resoldered / replaced and the circuits checked and realigned by a qualified tech familiar with Hitachi projection sets.

Right side convergence


A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.
