The red light on my TV is flashing but when turned on the green flashes and then turns off. I have no picture but I do have sound
Your power board is defective and that is why it is not allowing the TV to stay on. Or try to hear any clicking sound when the TV is turning on. If there is a sound then your panel could be bad because the Panel needs power to be power on but then it will shut off the TV because there is not enough power for the screen.
Please describe the problem more accurately. Flashing red usually means 'stand-by' state, flashing blue/green - starting up. When (during that) do you have a sound? Are there any 'high voltage' sounds like soft screeching from the screen? Is it LCD or LED?
