Question about JVC AV-48WP74 48" Rear Projection HDTV-Ready Television
I only had a convergence problem , now I have more!. I removed the Convergence PWB, and Replaced BOTH IC804 and IC805 with two STK392-150's. Now, when I plugged the TV in, the "power" button would go on "blue light" but, no picture, no sound. The "blue" power button is not workable; the only way to turn the TV off is to unplug. Thanks for the help.
You need to check first for solder splashes or bridges created when the new Ic's were installed,the next thing to check is a disconected conector or might not in place fully and then check for loose conections in the main board,all that movement might have loosen something more than before,check the horizontal driver transformer,the horizontal output transistor.Be careful
