Greetings!

I live in Greece and almost a month ago I purchased a CTF800 touch screen from CarTFT.com...

Everything was perfect until yesterday. I powered up my PC and CTF800 was not working good any more.

Symptoms randomly are:
1) CTF800 keeps rotating between "VGA", "AV1", "AV2" inputs continuously.
2) When CTF800 stays at "VGA" input the "VGA" on-screen logo (up-left corner) remains and menu keypad is not working.
3) Screen looks like washes-out or having big distortion.

Note that there are some times that CTF800 works perfect, but some other times there are the symptoms I wrote above in random order.

Please give me some advice/help...

PS.
I tested CTF800 in 2 different PCs and I concluded that the problem is not coming from the PCs...
