Question about Apex Digital GB55HD09W 55" Rear Projection Television
Hi, Thanks for the suggestion on the website for replacement ic chips for my gb55hd09w television. But now after install of the new chips when i turn on the television and try to converge i don't get the red crosshairs, blue is fine, and you see three large red streaks or smears starting 1/3 in and then trailing to the right. after you exit the convergence the picture now longer has that old 3d movie look but the picture has a significant red wash. Any suggestions you have for me would be greatly appreciated.
Thanks again, David
Did you check for open resistors in the convergence circuits? Often that is what happens when the old ICs wear out it will cause a couple resistors to burn open, and they show no outward sign of being bad. Also double check the IC pins connections for solder bridges thats another common problem, I always use a magnifying glass to double check my solder when ever I do convergence or any IC work where the pins are close. But with the streaks youre describing I would think maybe resistors.
