Hello, I've tested my installation and I have a problem with my screen maybe you can help me.
So the amp, the HP and the computer are OK.

But when the computer starts the CTF700(-SH V2) screen lights up in blue with the message "AV1 no input signal". I clic on the screen button to change the source and I have the message "AV2 no input signal" but when I clic once more to have the VGA source the screen goes black and I can't do anything.

Do you have an idea ?

Thanks.
