JVC LCD TV LT-42X688-powers on, blank screen. no picture,no sound

TV turns on, then flashes "JVC Digital Television" splash screen, then goes blank. Cannot access the Menu with either remote or button on the side. Cannot do anything with remote except power on and off (and even power off is inconsistent). Have "reset" by unplugging for 4 hours. When re-plugged in, it showed menu briefly, then went blank again!

You most definately have bad capacitors in the power supply. try and get it repaired as soon as possible, not an expensive repair that iv'e seen.

When turning on tv. screen will display Bravia image & then go blank. red light flashes SIX times


Power off the television. Wait a few minutes, then power it back on. If this does not correct the issue leave the power on, point your remote control towards the Sony television and hold the down arrow button. While holding the down arrow button press the "Power" button. Release the down arrow button and the Sony TVicon1.png will reset itself to factory settings. Once the television performs a scan on itself your problem should be gone.

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.

There is a black square in the middle of tv


That is coming from the closed captioning. It has been turned on and it is in text mode. The captioning is most likely coming from the television but it can also be coming from your cable box/satellite receiver. Find your television remote's cc button and press it until it says off on your screen. If your remote does not have one closed captioning should be in the menu. If the text box is coming from a cable box there are a couple of ways to disable it not limited to a button on the remote and a hidden menu you can access when turning it off from the on off button directly on it and pressing the menu button located directly on it.

Original remote lost. have universal remote. cannot program TV


On the right hand side of this television there are panel buttons. It appears that your son in law knocked the tv out of the correct input. Press the input button in order to cycle through the 5 inputs. Typically pressing the input button on the side panel of a television and pressing it again and again and again will make it change inputs. Universally the buttons on the tv panel function as follows: Channel up moves the cursor up. Channel down moves the cursor down. Volume + moves the cursor right. Volume - moves the cursor left.
Hope this helps

Can't play dvd player on JVC tv; I don't have a JVC remote.


I hooked up a Pioneer DVD player to my TV and when I play a DVD the volume cannot be controlled by the TV. It just plays at one level and on the louder side. When I'm watching regular TV and the DVD player is on and playing a disc I start to hear the DVD soundtrack at the same time as the whatever I'm watching on TV. I should not be able to hear anything until I switch over to Video 1. Any suggestions?

The digital clock on my 30"JVC is showing in the bottom of screen


The menu screen does not function the display. Without the original remote or a universal remote that does not have a display button, try unplugging the television for at least 2 minutes or more and plug the tv back in. This should reset the tv display. If the universal remote has a display button, depress the display button until you get the desired display results. Reference the user guide below for the display button.

Frozen digital screen


Set TV to standby and press Info, menu, mute then power. The set should turn on with the service menu available scroll down until you select reset press right hand arrow next to enter and then enter. TV will turn off. When switched on it goes into Plug and Play mode to reset the analogue and digital tuner. Allow a full reset then you should be ok.
