This indicates a fault on the Power Supply.

Do you have the technical ability and equipment to open the unit and look at replacing PCB components that could have failed?

The tv has power .the red light is on ,but when it turns on,the green light comes on but then it turns right back off ant the light goes back to red it has a round 1/2" button like plastic plug in...


Tod,
The little plastic button you are referring to is the IR receiver for the Remote. When the TV turns itself off, are there any flashing lights on the front or rear of the unit. Look through the vents in the rear for any flashing lights or try tuning the tv on in a dark room and see if any lights flash and reflect off of walls. If there are flashing lights tell me how many flashes and what color and I will try to look them up in the manual.

Power light keeps blinking Red and TV will not turn on


Is the light blinking constantly or is there a long pause then more blinking. If constant check the lamp door switch . Usually it is broken or jammed. If you jumper it and the set comes on that it. 4 blinks is bad fan.

Sony bravia tv


Solution is simple....

First, unplug power cable from the back of your TV. You will notice the flashing light is still flashing. Don't worry, go to the Second step.

Second, keep pressing on the POWER button, located on the panel at the top of your TV, to shut off your TV. This will stop the flashing light from appearing.

Third, Plug the power cable back onto your TV

Fourth, press the POWER botton ONCE, using the same button used in the Second step to turn your TV back on.

Fifth, you will see the POWER light comes on, as normal.

Sixth, using your remote control, press the green button to turn on. Your TV should work as normal.
