My tv went dead during a lightning storm. I heard


The sound could have come from one of your power capacitors. You could tell if one of them is no longer operational by looking at them; they will be burned, or blistered, or will be bulging. If this is a CRT type of TV ensure that you only look inside if you are fully aware of how to deal with the lethal voltages that are stored on the inside of the unit.

JVC TV AV-32870 will not turn on. blinking timer light


Worth taking it in since it is hard to find a new TV for less than $300. I have a 32 inch JVC iart that for about 2 years would turn itself off and the timer light would blink. Only thing that worked would be to disconnect and turn back on. Eventually, the tv "popped" I could smell something that burned out and within 3 weeks tv went "dead" Took it to a tv repair place and replaced power unit for $150. I had similar problem with a 19 inch Philips and that tv has been going strong for 4 years since repair.

Good Luck

JVC AV-32FA44 32" - No Picture, but sound OK


You could have a power supply problem as parts do go bad. Why your set faile is a mystery.. Of course if your not a technician, a TV set is NO place to be experimenting with. It only about a year old you say But get the papers on this set if you can find them and make sure as there is a 12 month warranty on this model. You should contact JVC At 1-800-252-5722 or online at http://www.jvc.com/support/. Good Luck
