Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television
Its like from the speekers Pop...Pop....Pop...Pop Like that I don't get any thing on the screen just Blank, it Just Pop...Pop.... Pop...Pop from the speekers
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.
