Display disappears after 1 second

[eltesco1]

Hi there and thankyou for such an amazing library! What a great job.

I wonder if you could help me with this issue and whether there is any fix I may be able to make in code or hardware.

when I connect to a specific display my composite output comes up for a second nice and clear and the then vanishes. It seems to be the display not detecting a proper signal?

tried both PAl and NTSC also tried adjusting resistors. Any ideas?

Unfortunately the display is specific and I can’t change it.

thanks again in advance!
