I switch tv on it works for a bit and then i turns of with the bulb light flashing. (Middle light) i try turning it on again it comes on but then turns off again with light flashing.
I suggest you take it to a repair shop while it is still powering up ok. The more you delay and keep trying it the more damage is possible. This problem requires a TV repair expert.
