I have a jvc hd52z585. while watching tv it turned off and the lamp light and the power light are blinking at the same time. i have unplugged the tv for a couple of hours. when i plugged it back in it does...


very easy.
there is 1 thumb screw behind left speaker grill.unscrew it to remove the grill.the lamp is behind that.after changing the lamp,go in to CUST.MENU,scroll down to reset lamp timer. Best price for lamp is pureglare.com. Inspect the lamp for internal glass particles for 100% verification of being bad. Also at the root of the glass stem in the middle look for bubbling of the glass. This is another sign of a bad lamp.

Hi..pls..help..my jvc television, im watching then turn off have a power but sadly it has a line at the middle of monitor and turn off.


You have a vertical amplifier failure or dry solder on the vertical IC. When cold if the TV works for some time and then you are getting a thin white line in the middle of the screen after some time -- its a dry solder problem. The vertical IC runs very hot in the TV and develops dry solder after a few years.Will run when cold and switch off when hot.
Are you well versed with electronics to do the repair yourself ?. If so, revert back and I will guide you if you mention the TV model #.

I am watching my 14 days old JVC 21"TV but


Hello
Your TVs power supply regulator section has got some trouble with it, that is why power indicator doesn't light up. You have purchased it only fourteen days back, surely there will be warranty for it. Do not open the TV. The company will give no concession if the set is opened. Send it to the authorised service center and get it repaired. Some power supply faults may fatal, and may have to spend more. Since your TV is a new model, spare part availability in the open market may be difficult. Send it to them and let them do the work. OK.

Hello, I have no sound on JVC AV-56P575. When


I have had the same problem. It usually happens when changing from a non-HD channel to a HD. It has been doing since the purchase of the TV. Instead of going through the headache of a service call, I have been turning it off, wait a couple of minutes and then turn it back on. The sound returns and the issue will not repeat itself for at least a couple of weeks.

No picture.


The lamp is turned on by a high voltage ballast, very similar to the ones in your fluorsecent light fixtures. Your ballast is starting to fail. You should have your TV serviced by a JVC authorized service center because they have the training to deal with this issue. Waiting until it fails could very likely cause more servere damage especially if it fails shorted then the power supply will need to be replaced as well.
