    Let me add a few photos of what is called convergence trouble==if they look anything like your problem I can tell you exactly what is needed to repair the set in the least expensive way.

    As it happens someone gave me the exact same set you have and I can provide photos of the circuit board that needs to be removed etc.

Tv comes on then goes black power light blinks on and off modle # JVC AV-56WP74 56


Check the coils on the main board. Coils mean round ferrite donuts (1 inch or less) with copper wires on it. I have seen this come out.
if not check convergence amp ic's

You have an convergence problem, There are 2 IC's that go bad and a few resisters that can change value. If you flip the board with the Chips inspect the pins for cold solder joints. The IC's can be purchased from matelectronics
