P4Update_v7.4.zip

You have the latest version of the Fli-Fi chips

I dont think it will help. The bridge chip has AFAIK nothing to do with native screen mode applications, only RTG ones.

Try changing your fli-fi mode promotion back to 1:1 50Hz that should stop the jumping.

I cannot say how important it is to take care and not use too much force when removing the MACH220.

The plastic that was used for the socket has denatured (on all boards) and is now more like glass than plastic. Shatters very easily.

I used the correct PLCC extractor tool with mine and STILL cracked the plastic (very slightly).

Take your time, get someone or something to hold the board for you so you can used two hands.
