How old is the TV? Usualy the most common problem with these Projection TV's are the LAMPS. They can last anywhere from 1 yr to 3 yrs. They usualy need to be replaced after 1yr and a half (18 months). Manufacturer's usually warranty them for that period of time. There is an access panel in the rear of the TV. If you open this panel you can see the lamp. Check it and see if it has gone out.

Unless this JUST started happening AND the TV worked previously, or you recently added a device to your set up, I am guessing that you simply are on the wrong input. For instance, I have a playstation connected to Video 2 and if my TV is set to Video 2 input AND my playstation is NOT on, the screen will be lit, but no picture. Make sure you are on the correct input.

Hey I was cleaning my computer and Unplugged the PW SW and PW LED from the motherboard. When i replugged it in the computer wouldn't turn on. I've tested the Power supply, and it's fine. So at one point...


Switching the connetors should not have damaged the motherboard. Have you tried disconnecting all your drives, removing any extra PCI cards, and removing the memory just to see if you get the necessary beep code? Also, try removing the BIOS battery and putting it back in.

Static shock can cause problems but I have not seen it happen in over 10 years of personnal experience.

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.

Power comes on ds lite, green lite comes on, gets brighter, then screen flashes and all goes completely off again.


Sounds like the actual processor in the unit has failed, it should be a free repair from Nintendo. Either way you will need to give them a call, their number is:

Our tv will come and then shuts right off and the power lite will then flash. You can only turn the tv back on when unplug and then plug it back on


These set have common problems with capacitors in the power supply. Likely the set will eventually not turn on at all.

Not Working


its the high voltage regulation,the power supply regulators bad or could even be a bad picture tube. now If you have done electronic repairs in the past then I would advise you to get a service manual and see whats going wrong by monitoring the B+ while the set gets turned on BUT if you dont know what a regulator is I would advise that you call or take thats right take the set to the repair shop and see what the friendly person says. if they have a flat rate thats a good thing. BUT if they have an per hour rate then thats where your gonna have to say to your self >> "myself?? how much did I spend for this tv?? is it worth repairing??" Its all on your guess. Good luck
