GG new screen and 34v line
Post Posted: Fri Jul 01, 2022 12:06 pm
The LCD in question is this one (instructions in the description):

The lcd requires a few components to be removed.
They are marked with red in the attached schematic.
My question: can I remove all the components on the 34v line (the bottom part of the schematic)?
Even R31, Q5 that are on !GG?
I'm asking because I have a few boards very corroded in that area and I would like to remove the components that aren't needed so I can clean it better.

Problem 2. A few consoles are missing the brightness pot.
Can I use this one (the 3pin version):

Note: the schematic has an error. D4 is in fact the second half of D1
