I have a jvc av 48wp30 rear projection screen television. About 5 months ago the convergence went out so I had a tech come out and replace the convergence IC's, he used two stk 392 110's. A week ago ago the screen got an hourglass shape with the top and bottom screen bowing badly coupled with double vision look on screen. I used the remote to attempt to adjust the convergence but although I could ge the arrows to move, i was unable to get the arrows to move far enough to get them lined up properly. Then just a few days ago after the set had been on for about 10 minutes it made a popping sound and the screen went dark. The blue power light continued flashing so i unplugged the set. I ordered two more of the stk 392 110 convegence ic's online and received today. I carefully removed the old IC's and very meticulously reinstalled the new IC's. I even used a magnifying glass to make sure all new solders were secure. The screen now lights up but i still have the convergence problem and when i attempt the use the remote to adjust the convergence the arrows won't move at all. I have looked online to try to remedy the situation but have not found anyone with these exact circumstances. I am not a techie by any stretch of the imagination so in laymans terms can someone advise me on what they think the problem may be? Any help would be greatly appreciated.
