Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary..

How to turn off clock on jvc tv


Press the "Menu" button to set the lock code for your JVC TV. A padlock icon will appear on the menu display.

Press "Zero" to access the lock code function then use the left and right arrows to select the four-digit number for your code. Use the up and down arrows to move to the next area of the display.

Select the up or down arrow to finish your lock code then use the left or right arrow to save your lock code settings and exit the menu. You can return to this display if you forget your four-digit lock code and set another code.

Write your four-digit lock code down and keep it in a safe, private area.

Select the locked TV channel you desire to watch or want to unlock. A message will appear on the display requesting you to enter your lock code to unlock the channel.

Unlock your JVC TV by entering your lock code on the 10-key pad. The message "Invalid Lock Code!" will appear on the screen if you enter the wrong lock code.

Parental Lock


Try unplugging the tv for a few minutes. This reset the front panel lock on my JVC tv. I got it from the manual, which I found at the JVC site by Googling the specific model of the tv along with JVC and manual. I found the manual right away.

HDMI input failure


Hey guys, had the same problem. Found this solution on the web. Worked for me.

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 reenabled.


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.


This should work.
