Question about JVC Projection Televisions

3 Answers

Hello, I have a JVC LT32X576 LC TV Manfg in Aug 2005. I was watching and it turned off on its own, I thought that the sleep timer got turned on so I pushed the on button on the remote and nothing, pushed the power button on the side, nothing, checked to see if the unit was getting power and it was 121.7 Volts. I took the back cover off and checked the fuse, it was blown, I replaced it with a 250V 6.3 Amp fuse (same specs as on the blown fuse and stated on the board) and the blue power light came on as soon as I plugged it in, I tried turning it off but no responce, after about 30 to 45 seconds I can turn it off by pushing the main power button, and back on again but you have to wait 30-45 sec to be able to turn it back. The only thing that turns on is the blue LED nothing else. The relay clicks when the light turns on and off.

Hi,

Primary suspect would be the Power Supply board. Most models uses a common PSU P/N LCA90348. This is based on your post that the main fuse blew. It still could not be ruled out that any of the other boards/components are not faulty. The best approach would be to reference a service manual or at the very least a schematic diagram with voltage readings. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Well the clicking noise is usually an indication that the power supply has failed. You will have to replace the PS board.. If your tv is under extended warranty then you can make use of it to get it fix "Free of charge". Otherwise you can either get a tech to fix it or try fixing it yourself provided you have the experience.You can search for the part at www.partstore.com

There are many things that can cause a television not to turn on.

Some problems can be:
GA_googleFillSlot("TL-IMU-Article"); as simple as an internal fuse, while others are more complicated, like a defective board or power supply.

There are things not even related to the TVs power system could cause the set to be dead. Given the wide variety of possibilities, there is no chance of making a remote diagnosis. Like a blind man in a shooting range, any guess would be a shot in the dark. That's why, you'll need to contact a JVC service center. Once they inspect the TV, they will be able to tell you what went wrong and how much it will cost to fix it.

Digital input not working and greyed out on the menu.


Most JVC TV's with HDMI and Digital Input have an optical sensor inside the case to sense if someone is trying to bypass the hardware encryption. My JVC was exposed to sunlight prolonged sunlight and triggered this optical sensor which disabled my HDMI ports. This may be the same situation for you.

JVC HDMI Port Fix

Turn the TV on, and enter the Service Menu. Select 2 for Self Check. Then turn the TV off, and after the fan turns off, unplug the power cord. Reconnect the power cord, turn the TV on, and the HDMI port is re-enabled.


Here's how to get to Service Menu:

Before entering the SERVICE MENU, confirm that the setting
of TV/CATV SW of the REMOTE CONTROL UNIT is at the
"TV" side and the setting of VCR/DVD SW of the REMOTE
CONTROL UNIT is at the "VCR" side. If the switches have not
been properly set, you cannot enter the SERVICE MENU.
1) Press [SLEEP TIMER] key and while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key (Fig.2)
simultaneously.
2) The SERVICE MENU screen of Fig.1 is displayed.
3) Verify what to set in the SERVICE MENU, and set
whatever is necessary (Fig.1).
Refer to the SERVICE ADJUSTMENT for setting.
4) Press the [BACK] key to return the SERVICE MENU.

Tv switches off after 5 mins


There might be three or more reasons for this:
1) The sleep timer may be on causing the TV to turn off after a preset time.
2) If sleep timer is on and no signal from the remote is received for a preset time (Samsung: 15 minutes) the tv will turn itself off.
3) The TV may have been turned on automaticaly with "On Timer". If so, and no signal is received for a preset time (Samsung: 3 hours) the tv will turn itself off.
4) A fan is not working or a vent is blocked causing the TV to overheat and turn off.
For 1) thru 3), go to the "setup" menu and make sure "sleep timer" and "On Timer" are turned off.

Sure. I'm not sure if you can do it without the original remote, though. On my remote, you need to have the tv turned on, then press the sleep timer, then press the display and video status buttons simultaneously. This enters the service mode. Then, you should see an option for self-check (#2 i think). Enter that, then you should see 2 vertical columns of different inputs. From that screen, power the tv off. This resets all the ports on the tv.

My HDMI port on my JVC 48avp575 rear projection TV is not working.I've tried all menus using sleep timer instructions, etc. ... no luck. I can change to ng's to ok's, but as soon as a device is connected,...


Jvc have a little problem with there HDMI ports of by some how you run the set with the back off or get to much light in the back the HDMI locks up. So you have to reset the set, this isn't to hard, from the original remote have the two switches (if any) have these on TV and VCR or both to the left, next hit the Sleep Timer now before this disappears from the screen hit both Video Status and Display at the same time, this brings up a service menu, hit button 2 this is the self check, now turn off the set then unplug it for 30 second and the HDMI should work

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.
