I HAVE A JVC BIG CREEN TV AND IT SOUNDS LIKE THE SPEAKERS ARE BLOWN. I CALL ATV REPAIR MAN HE COMES OVER TAKES APART AND SAYS NEEDS TO REPLACE SIGNAL AUDIO BOARD AND IT WILL COST 100 - 300 DOLLARS. ONE WEEK LATER HE CALLS AND SAYS $995. I TELL PUT IT BACK TOGETHER, THEY DO AFTER THEY TRY AND CHARGE FOR WORK OR PARTS I DIDNT OK. HE COMES PUTS BACK TOGETHER AND TURMS ON SHOWS ME IT WORKS. I LEAVE FOR VACATION ONE HOUR AFTER HE FIX'S TV. WHEN I RETURN THE FIRST TIME I TURN THE TV ON IT ONLY HAS A PICTURE FOR ONE HOUR THEN GOES BLANK. IT NEVER DID THIS BEFORE. COULD HE OF PURPOSELY DID THAT? IS THERE SUCH THING AS SIGNAL AUDIO BOARD? CANI REPLACE IT MYSELF.
