No display to the tv

Hi everyone!

I have a customer who brought in their console which works perfectly fine handheld but not displaying to the tv on their dock. We tried their switch on another dock to make sure that wasnt the fault.

So orignal I thought this would be caused by te P13 chip so I went straight to there and tested the caps around it for any shorts but all seems to be running smoothly. No other shorts can be found on the board which is interesting,

Does anyone else know which chip or what else could be responsible for this error?

Appreciate the help!!
