On my plus it had no video, in the end it was just a case of resoldering the "J" connectors (the multipin rectangular connectors) on the analogue board.

I've heard of C1 capacitor going, mine it looks similar to yours, it has hot glue around it like it has been replaced at some point.



The connector in the middle that looks like 9 solder joints in a row, followed by a space then a singleton seems to benefit from resoldering
