Yep, sure sounds like a tuner pproblem my friend. good diagnosis! If you have any soldering experience and know how to work on solid state circuit boards, then you should have no problem replaceing the tuner for this set. Now it could also be a problem with the HYPER PCB assy. This is what controls the tuner and some sets the tuners on the hyper board. the complete HYPER board is avail. at http://www.partstore.com for about 165.00 + shipping. You can also check with http://ptscorp.com for a rebuilt hyper board assy. If you have no experience with TV repair PLEASE stay safe and call in a trained servicer to assist you with this problem. Good Luck

is the light flashing? Many things will cause a no power condition, might be shorted Convergence IC's, Z801 Ic could cause trouble, might want to call service man.

We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.
