i have a lcd 19inch tv.vga monitor when i use it on my pc the monitor trips of sometimes it comes straight back on very bright or it sits on a black and silver screen and i have to press pc button on remote to get desktop back did change graphics card to a new one but still happens (nvida geforce 8500gt)so i took my monitor with the problems put it on my partners pc worked a treat no problems i put her monitor which is just a vga monitor not tv combo and it worked without flickering of how odd is that i cannot understand that maybe someone can on ere.

I googled technosonis lcd1908 and it appears to have a problem with flickering off and loosing picture but I'm not convinced that's quite the fault your getting , I wonder if it simply doesnt like the output signal from your graphics card ?

what connection are you using , is it DVI or VGA or >>........

have you tried running it at it's native resolution ?

how confident are you of the integrity of the physical connection from the graphics card ?
