. It is more difficult than batteries on a remote.

You access the convergence board through the inspection plate that is located behind the front speaker grill.

You remove the board, determine if any resistors are burnt, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If you haven’t misadjusted it too badly, do the auto focus and it is back to where it was before IC failed. If it is still misadjusted badly, then resistors may be wrong value or open.

If you live around Calgary, try me instead:

or try the find a repairperson part of this website, maybe you will be lucky and someone is listed nearby.

Most rookies doing this job will cause damage and not be successful, and pay double for someone to fix their mess.

The STK392-110 are the stock ICs for your JVC. Chances are one or more of the feed resistors are bad. JVC TVs will usually have at least one bad resistor when the original ICs fail

JVC AV-56WP74 56 in rear projection convergence


If you remove the lower front panel where the speakers are then the small access panel you will see the convergence module right there in the front. It will have the two Convergence ICs attached to that heat sink. They are probably STK392-110. Then if you would like let me know and I will post a link where you can get the parts along with step by step instructions on how to do the repair.
