JVC AV-32730 36" picture problem..

JVC AV-32730 36"... the tv turns on fine, but after 5 - 30 min or so, "sometimes" the picture all of a sudden go's black. it makes a weird "zzzt" sound when the picture shuts off. Sometimes, it comes back on after a while, sometimes it does'nt. giving the back of the tv a whack sometimes gets the picture to come back on, sometimes it does'nt. Is it worth fixing ?

From what you describe, a solder joint has probably cracked loose in a power supply or deflection circuit, which is quite common. Since you do sometimes see a good picture, all of your major components are fine. Repairing cracked solder joints is a very easy procedure and definately worth fixing on a 32 inch TV. The first 2 digits of the model number indicate the size of the TV.

JVC 32" D series TV is suddenly black and white


Wow that's interesting, was there anybody watching your home while you were gone? There is a possibility that someone simply turned down the color level with the color control? Check that first. It's an unusual symptom. With composite video, component video or HDMI it's not usually possible to experience that defect. Since the color (chrominance signal) is usually inseparable from the luminance (black and white signal) I would check the color setting first. Other wise your set has become unable to detect that color signal... I bet it's a setting rather than a defect.

Happy Viewing

My tv turns on fine after a few min the picture go's half black,if I whack the side the picture will come back on for a while and go back to half black again, could this tv be fixed?


The set has bad solder connections, specifically in the vertical output section. When you whack the set, the connections work for a while so the full picture comes back. Then, when they open up again, you're back to black. A service technician with a soldering iron could fix this easily, and the cost would be far less than the price of a replacement.

Tv picture is black, sound is fine


Sorry, no easy answer here. On an older set this would be espected and not worth repairing, but you should take this to a TV shop for troubleshooting. Most likely culprit is the flyback transformer and/or the horizontal deflection.
Hope Ya Fix It.
