I killed my TurboGrafx-16

can we see a pic of the reversal on the region mod?

dude, measure the voltage coming out of the expansion bus.  If that's ok, work backwards (though saying that, if the RF doesn't work, it may well be something else entirely.  Maybe you knocked a cap or cut a trace?

What pin do I measure on the expansion bus?  I have checked the capacitors, and resistors multiple times.  The caps all look good.  No breaks in the solder or leads.  I thought maybe it was a circuit board cut too, but I've looked very closely at the MB and I don't see any traces that have been cut.

Did you clean all the flux off the board from your soldering?

Whatever signal you're using, so RGB or Composite.  Should be 5v coming out IIRC.

Yeah.  I even when at it with a soft toothbrush afterwards.

No, no.  I meant what pin?  As in pin #1 or #2 or #3.  I don't know what signalling comes out where on the expansion bus.

ah, right.  IDK if you're using composite or RGB, but this tells you what's what:

From My experience, when the wrong Region is selected for a game, it's just a white screen.  I'd check you modding again to be certain.

I've modded it twice with the same result.  It has been 'un-modded' now and it still doesn't work.  Pretty sure I killed something.

white screen, typically means that you have lost connection to a card pin, or bridged a solder joint.
as this happened during a region mod, and the TG16 board is low quality chances are there is a break in a trace near where you removed a pin.
its also possible you lost connection from one side of the board to the other

Thanks thesteve, and everyone that has tried to help me.  I am admitting defeat and sending the MB to BlueBMW for diagnostics.  No guarantees it'll be revived, but I've stared at it from every direction multiple times and I'm starting to go blind.

It is going to be shipped out to BlueBMW next week.

We will fix eeet!!

We will fix eeet!!

Beamer you are awesome

I hope so.  I do not want to be held responsible for the death of an old friend.
