Question about JVC AV-48WP74 48" Rear Projection HDTV-Ready Television
My jvc av-48wp74 won't power up and the power light flashes. The speakers also make a thumping noise. I have already replaced and upgraded the stk's could this be a new problem? Maybe the power supply?
When you replaced the convergence amps did you check and replace the resistors? it seems like they always take out two or more resistors. the problem is on the convergence board, i have the same tv that did the same thing. if the speakers are still thumping, you may have got a dud amp. i recommend using the factory stk392-110 amps. make sure all of your solder connections are good and none of them are touching. also, when you get the set back on you will need to manually adjust the convergence from the menu. you will need the factory remote. if you find bad resistors, the values are on them, but if you need the values and wattage, then use this page:
hope this helps you.
