Sony wega engine 3lcd. turns itself off

Have you changed the lamp? If not the lamps life is around every two to three years. The lamp is easy to change out. Most local repair shops carry the lamps. Hope this helps.

Dust lines? Please explain. Are they single pixle lines on the screen itself? These are the signs of a failing display.

look likes E H T problem. Watch the rear of the TV. If you find blue arc anywhere, you have to check that component. Take care while handling the E H T side near the picture tube.

Even if the TV is disconnected there me dangerous voltage present in the E H T connecting point of the picture tube body. Take service center help.

Please mention exact model number of Sony 50 inch TV to look for solution / information.

Generally speaking whent he set shuts itself down, the standby light will blink a code. This will be a count followed by a short pause and then the count again etc.

When teh set shuts down, count the blinks and post it here. That will indicate the circuit that has the problem.
