If the screen flashed when the TV made a popping sound, then I would suspect an intermittent heater to cathode short in the picture tube. When this happens, it usually takes out one to three output IC packs located on the CRT drive board. Even if you replaced the defective output packs which are soldered in and attached to metal heat sinks to restore the picture, the CRT could short again and redo the damage. For a 20 inch screen it is probably not worth repairing.

TV turns red,shuts off, stand-by light blinking 8Times

Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401, and 402. On some projection models of Sony TV sets, this code means that T8005 (flyback transformer), or the associative components in the high voltage circuits are defective on the D board.

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.

Projector screen turns off after 10-20 seconds

Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.

Red/Orange horizontal lines

it could be that the tv convergence circuit is going bad. One shure way of finding out is to go to the tv feature menu(picture,audio etc.) and select the customer convergence setting, you should get a cross hair pattern(cross in middle of screen). that cross should be white and by aligning the red or blue colors they should move left, right, up or down
