I have a jvc/av-65wp74 unit. The screen went blank and made a pop,pop,popping sound. we could not shut it off with the power button, which was blinking off and on. We had to unplug from the wall. we waited for a couple hours and tried again. did same thing, no pic,no sound but the popping noise. had to unplug from wall. Help! Please

The clicking you hear is probably caused by a relay that controls the incoming AC to the main power supply. This is a protective reaction to a problem in the power supply itself or an overload due to a failure downstream from the supply. This is not a likely DIY repair. You will probably need a technician to determine which of these two likely problems it is.

did you check the low ohm resistors. A JVC will almost always blow at least one and if the ICs are replaced without replacing the resistors the new ICs will fail instantly

JVC's have been known to develope audio problems if the Convergence ICs short considerably as often you can get a popping through the speakers or in rare cases no audio at all. I would install a convergence repair kit and see if that cures both problems. Your model uses the AV48WP74 - 65WP74 convergence repair kit. www.tvrepairworld.com has the repair kit and it also contains the CD with detailed repair instructions for your model.

it could either be convergence ics shorted or deflection board trouble
as to cost convergence 300 to 350
if its power supply 300.400
it would have to be isolated down to the exact location causing the problem
but usualy a great set to keep around

The Drive PWB for the Plasma Panel just fried. You can probably remove the back cover and easily identify the bad components

check the power supply board remove the back cover just follow the power cable/plug in cord, remember unplug the tv set first you will see a fuse on the power supply board maybe is pop/open if no luck sell parts on ebay will get $$$....

Classic convergence driver failure for this unit. I call it "the thumps." Convergence drivers are two large chips inside (STK392-110), one of which has gone bad, but both need to be replaced. There are also several resistors around the drivers that have also sustained damage and need to be replaced. I recommend a television shop do the work for you because, unless you have good, solid soldering skills, the board can be rendered unusable by excessive heat/prying, etc., and the HD input can be **permanently disabled** by opening the back of the Television without properly preparing it.

Its the power cap mine did the same thing about 11 months into daily use

uslay insde has screws holding it in then slide up

I'm having a problem with my JVC 65WP74 the screen shows double pictures at the top and in the middle.
