Setup won't find digital channels - coaxial cable connected but only shows cable analog
SOURCE: JVC LT 32E479 UNABLE TO SWITCH ANY CHANNELS
go to menu select TV settings select add a channel In the scan boxes type 1 and 3 or what every you have your Satellite set to Then hit start scan The TV will come on reset to channel 3.
SOURCE: Not able to scan for digital OTA channels on a JVC LT-32X667 LCD
Seeing as it does not have a digital tuner in it, I would think this would be the problem, you will have to get a box for it.
SOURCE: JVC LT-37E488 no picture, clear sound. Turn it on
You will need to do in-depth troubleshooting, please read below:
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.

>>>> * A word on coaxial vs spdif (optical) audio cabling - I always use coaxial if I have the choice because it is A) cheap RCA cable available anywhere in any reasonable length you want to run; B) can be extended and SHARED with other components if you have limited jacks available. You just have to be careful to make sure only one digital source at a time is turned on while using the other; C) RCA cable is impervious to problems arising from tight bends; optical physically delicate and won
