if when you turn the set on the display does not light up at all there is a good chance the display has gone, if you ring jvc they should be able to giv you a price of a new dsplay i will warn you it wont be cheap.
Offhand, it would appear that the 'Closed Caption' has been enabled in your TV. This can de disabled in the MENU/Settings. A more detailed procedure would be available in the owner's manual or pls post back to confirm if your TV is a JVC AV-27530.
The problem you describe is not really related to a timer function being set. The unit is in shutdown and the light is blinkng to let you know there is a problem.
There are several possible causes. the most common is a failure in the vertical deflection circuit due to a bad vertical IC and possibly a capacitor, zener diode and resistor.
it might be due to remote also like weak battry,buttonloose,loose contact.
if it is ok then check for loose contact in system control ic ckt.pr print loose.
as you say tv works ok so failure of components is rear.
