Any history available?
Do you get image for sure?

DP_INT_HPD goes high?
Check it with LCD connected!

At least check for image on external monitor.

Hi 2informaticos, Thank you for the quick reply. I just sorted it thankfully.

It tested as low ohms on PPVOUT_S0_LCDBKLT so I decided to inject 5v into that line and have a look on FLIR

The issue was with capacitor C8470 shorting.
Replaced and now works fine.

I was having an off day obviously for not just doing this sooner.

Thanks again
