    The HDMI input has never worked on my TLX-04011C 40" but I am trying to get rid of cable and really need this to work. I have tried 3 different hdmi cords of varying prices (up to $40) and none of them work. Tried unplugging everything and then plugging in my Roku to no avail. Is there anything I can do?

Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you save $300 least!

Input Problem


Mine was the same, except i also could not access HD Components.
Unfortunately i had to get some one in, as the circuit board at the back of the tv was burnt out.You might have to get a technician in to service and replace the burnt circuit board.

No video input -- all ports -- for JVC LT-37X688


JVC may allow warranty exception or some accomodation for 15 days out. You have 2 seperate issues

1. White lines spreading is probably a video process problem. I think this TV has 3 Boards inside. Middle one is most likely suspect followed by the one on the Right

2. HDMI input not working is because they were turned OFF. JVC TV's have a sensor that will shut off the HDMI if the TV's back cover is removed. This must be reset in the Service Menu.

Only HDMI2 input works


try attaching all the sources you have to hookup, have the power on , on each unit and then go into tv menu and run auto program. if this is no help your tv may just need a firmware/software upgrade, I don't know if they give the download to the consumer or not but if the auto programming doesn't work call LG @ 800-243-0000 tell them your problem, 4 days old really don't recomend having extensive service work but it is under factyory warr. so you have the option but if they think it's the firmware upgrade and you have a usb flash drive they may send you an email with the software.
