This may be a question for Ken or anyone that happens to have this monitor in one of their games with the applied mod.

This chassis came out of a Silent scope and is actually a WGM2775-U0GS35B. There is a mod to the position of Q710 and apparently a transistor was added after it left the factory by running a remote harness off to the side and mounting the transistor to a separate heat sink. Yes, I already checked the WG site and there is no mention of a Q710 for the 27 inch or 25 inch monitor. I can find no factory bulletin either to identify the part number needed. This is not the sync mod for the U2000/U5000 that many of you are thinking of. I have seen the mod in another game but of course the transistor does not have a part number on it. Any help?
 
The k7501 schematic I got a couple of years ago that came with a brand new 7501 monitor shows Q710. It says it's a type BDX53A (NPN Darlington).

Schematic # 069X2898-100A is what I have.
 
The relocation of this part was a lesson learned from the U5000 that had all the transistors on one heat sink. Way too much heat concentrated in one area.
