Mac Pro 2013 (Trashcan) got black screen on boot

Hello, my Mac Pro 2013 Trashcan with Dual Firepro D700 GPU cards now no video signal. It works like normal for years, however recent days it couldn't wake from sleep. I try to restart, boot it up but no video signal. The chimp sound still there, nothing show up on display.

I have tried reset SMC and NVRAM, and it sometimes can be boot again with video signal but the issue still there. When i run Apple diagnosis tool there is no error code. The system still works like a charm except when it can't boot with screen video signal on.

I've heard there is maybe issues with GPU, can anybody suggest how to fix and solve this ?

Thank you.

Have you tried using another Thunderbolt port or the HDMI port? The Thunderbolt ports are paired to different busses with one of the pairs linked with the HDMI port (see picture diagram).

If the GPU is bad, then I would retire the system. Apple had a free GPU repair program at one point for a small number of these GPUs, but I found GPUs outside of this program also had the same issues with our organizations Mac Pro 2013s. I personally would not spend any money on this Mac even if the computer was still current due to the extreme price of the GPU (there are two GPU boards & the free repair program replaced both, but outside of the program only one of the two boards gets replaced...still expensive & doesn't always solve the problem at least with our organizations Mac Pro 2013s).
