Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television
My son does not have his book and I need your help on how to do the convergence on his JVC 56 in. rear projection HDTV. Had problem with red lines and will be replacing the STK392-110 tomorrow. Can you tell me what I might need to do after replacing.
Thanks Robert Email firstname.lastname@example.org
. 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.
