Insignia 47lcd picture goes out after 10min, have sound

[snake91876]

Insignia 47" lcd plays great for about 10 mins and then the screen goes black. I have backlight still i believe when i look in vents i see lights on both ends and have some light around the edges of the tv faintly. I have sound. I have no on screen menu/display once it goes black. Anybody familiar with this i looked at power supply, main board, tcon board and see no bulging or discolored capacitors. What should i be looking for, i see many people with this issue having tcon board problems. Once before it went off it distorted the picture all weird shaped. When i cut back on it comes on immediatley normal for a period of time. the more i do it the shorter the duration that it stays on . Eventually i power it up and get the black screen from the start i guess once its hot enough. Please any advice would be good im stressed. Thanks

Check for fuses on the T con and the main board.

Post good clear pictures of the boards in good light without flash.

Cool, im in the process of taking the pictures now and will post as soon as possible. I did want to mention the tv power on light is blue when on and as soon as i turn the tv off it flashes a red light 7 times, is this significant to anything. Thanks pics coming soon!
