Game Gear CN3 connector questions
Post Posted: Fri Jun 28, 2019 3:49 pm
Hi,

I've a Game Gear Europe double asic that has been modified for the rgb output with the classic scheme. Since some times it doesn't work (not the rgb out not the display image that remains white) and I'm trying to undertstand why.
I've not seen anything strange on the board but one thing I've noticed is that the CN3 audio connector has the pin 6 (the wire after the empty one) badly detached from the broken blue pcb connector. Also close to that there's a resistor bridge (with a classic big resistor not the smd one) from the right point of the (empty) C78 to the right point of the (empty) R11. I don't know if this is part of the mod or it was some factory "last moment" resistor installation; also the left point of C78 seems to have soldering like the CN3-pin6 may have been soldered there.
Are there any relationship between these components and the connector pin 6 (the one after the empty pin 5 of the connector CN3).
Also looks like something burned on the pcb close to these components.

Thanks.

That's the connector and the resistor.

it honestly looks like someone took a soldering iron to it and ripped that far pin out... Does not look like a good mod at all... The resistor bridge does look factory but idk... Im going to ask a friend and see if he can send me a pic of what this board is supposed to look like and ill post the results here if your problem isnt solved by then.
