Do you mean the JVC Logo keeps appearing?
If so, call JVC for the software update. I believe it may even be posted on their site. You can check in the TV menu to verify. You should have F108 or higher.
If the update doesnt apply, you need a Digital PWB for the TV because it is defective.

That problem is usually cause of bad capacitors on the power supply section..
As you stated your TV works fine and after a minute the red light comes on...
That symptoms is cause of bad capacitors..Normally bad capacitors can check visually if the capacitors look like leak/bulged on the top that is the indication of bad one but not all bad capacitors are bulged some are not so in that case you have to used a special meter called capacitance meter..
This is the sample picture of bulged capacitors:
