Playchoice 19" LCD upgrade single monitor

The chip at location 8T has some control in the menu departnent.
I ordered a replacement, and if anything changes I let you know.

I'm getting closer.

Where did you order the replacement chip from?

I ordered from hobby roms.

The bios 1.1 eprom came today.
But sadly it did not fix the menus issue.
Having replaced the Z80 with a fresh one, and now the chip at location 8T, I am at a loss on what to do next.
If anyone has any ideas, fire away.

Thanx!
