We have a JVC LT-37XM48 showing multi-colored horizontal and vertical lines.


replace the power supply...ebay sells them; the power supply has a number on it to tell you which one you need (be sure to leave the set unplugged for at least a day before you replace the power supply (to avoid a nasty shock from the charged up capacitors on the power supply board.

Screen damage from baseball


not economical to repair----front screen is called a display panel and rather fragile, cost of the part alone will be more than a new set will cost, sorry but time for a new set.

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.
