Screen turns green then shuts off

What kind of TV is it?

The green crt is dawning to much current, and that is why the TV is shutting down, if you remove the speaker cover, there is a focus block, that has six controls, on it three are for red blue, and green screen voltages, if you turn green down where the retrace lines go away, the TV should stay on, it is not worth fixing, you would be better off getting a new LCD.

The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

check the supply at horizontal driver trans former ,if voltage is correct at ho/driver trasistor ...then check allthe fusible resistances from power supply,,,if tv is taking h/oscillation for awhile ,,give more screen control in lot,,, & see for a horizontal line ,,,before tv becomes off,,, if so vertical ic problem...

One or more of the CRT colors guns it dead,must be replaced.

Green light flashes 5 and then red light flashes 6

Call a good TV Tech and have him check for vented capacitors in the DM module or blown pico fuses on the -24 and the +24 volt lines.If fuses are blown,it indicates the convergence amp IC's are bad.The fuses solder into the board.

One or both your screens have blown.

Try removing the motherboard from the screens and attach the battery the green light should turn on and stay on.

Now attach the lower screen and turn on. If the screen is ok the screen and green light will flash and then turn off. (if the screen doesn't flash the bottom screen is you're problem and will have to be replaced)

If this happens the problem is then you're top screen which you will have to replace.

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

My tv too had a blue screen problem. Then it started to shut down after staying on for less than a minute. I thought that I would with a huge repair bill but I followed the directions at this link: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html and now my tv works perfectly.
