I have had my laptop hp pavillion g6 for 4 years and now when i turn it on it shows no display and turns off by itself after 5 secs. Sometimes if i spam enter and f11 it boots up loads into windows but it's display is still black and I have to use my tv. When I attempted to reset it thinking it was a software issue causing this it restarted and wouldn't start again it did what I said at the start. I tried to turn it on again and spammed enter and f1 and it started without shutting off after 5 secs but now it won't display on my tv.
