My Tv started with flashing red/orange colors. Then later the screen turned red/orange and the TV shut off. When I attempt to turn it on again, the screen stayes red for a few minutes then shuts off.


The problem based on the model number is in or around the red picture tube---the bright red screen causes the set to draw too much current and the shutdown circuit detects this and turns set off--self protection.

Each picture tube (3) has a IC chip on the board connected to it--shorted chip or bad picture tube.

Shop repair in most cases.

My Sony big screen rear projection TV model KP=51HW40 produced 2002 screen flashes red then shuts off. We can turn it back on and it will run for 30-60 minutes and then it repeats red flash. Is this


The Problem you are having is a Cathode to Grid Short in the Red CRT,When it Shorts the screen will Go all Bright Red and shut Down,The Best fix Would Be to Replace the Defective CRT (GUN)

I try to turn it on but it just blinks on stand by


Probable Lamp. If lamp hasn't bown the red Lamp Lite won't flash but other lamp issues cause stby timer light to continue flashing. If stby red lite is flashing, count the no. of times flashing - could open thermal fuse (6X flashing)

Turn on pic turns red with thin bright red horizontal lines


Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.
