CUH-1115A - WLOD - Port, IC and Diodes Changed

Reaching out for any other ideas. I’ve repaired a ton of PS4’s over the years. And this one has me stumped.

Is it possible to get a white light and still have an issue with the GPU? I’ve already replaced the HDMI IC, port and several diodes and caps, as well as the filters. There’s no visible damage, but the customer did have a lightning strike that took out the tv. Measurements around the hdmi area are on par with a known working board. Fuse is good. But still WLOD persists. Anything else I can check specifically?

Thanks for any input.
