Did you run a wire for ground on the chip?

Also, you can snap off the unused switchless board part.

Yes I did.  I ran it in after I took this picture.  I have it soldered to the left of the "CN102" connector.  Right above the number 37, and 38 on the MB.  It's soldered to one of the spots the RF shield is usually soldered.

Yeah, I know I could snap the useless bit off, but it helps me whenever I'm soldering (gives me something to hold) so I just left it on.

[EDIT]  I installed a proper SPDT switch today.  No luck.  I'll try removing everything and reconnecting the original HUcard pins this weekend.  If that doesn't work then I have killed  :shock: a TurboGrafx-16.

*Double post*

So tonight I removed the wiring and the RMC from my TG-16.  I had a hard time believing the region mod chip was at fault so I decided to wire everything back the way it was.  It wasn't easy, but I think it came out pretty nicely;



So I wired everything back to factory default and insert it into the TG-CD docking base.  I flipped both power switches.  Nothing.  Just the same white TV screen.  I check the RCA cables (again) to ensure they are plugged in correctly and are inserted into Video 1.  They are.  I pull out the Keith Courage HUcard and insert another one.  Same result.

I'm baffled.  I don't know what has happened, but it's obviously something I did while trying to mod the console.  It definitely was not the region mod chip at fault.  Old PCB's like this aren't exactly complicated, but I don't know what the issue is.  Visually the MB looks identical to what it looked when I first cracked open the housing.  The fuse is good, capacitors are good.  The only visual difference is some very minor melting (visable in the pic) on the HUcard slot where I came too close with the soldering iron.

As a last ditch effort, I went ahead and soldered the RF shielding back into place.  My thought process being that maybe it provided a GND that I wasn't aware of.  Unfortunately, it didn't help.  The result was still a white TV screen.

For anyone reading this, I would like to state whole heartedly that I do not blame the region mod chip for this failure.  This is obviously a user error (the user being me).  I obviously screwed something up at some point along the way.

I will remove the RF shielding later this weekend and inspection the MB closer.  If anyone has any troubleshooting methods for getting my TG-16 working again I'm all ears.

I may have just killed a TG-16.

*prays to turbo gods for forgiveness*

[EDIT]
BlueBMW, the reason why I mentioned pin 29 earlier was because of this post;
Quote from: BlueBMW
edojapan's TG16 is the first US system I've ever heard of needing the pin 29 grounded on in order for the region switch to work.  I'll be adding a note to the install guide.  Maybe some of the very late (or very early) TG16s were a little different as far as region lockout goes.

Congrats on the great install edojapan!

It's from earlier on in this thread.

Small update here...

It appears that the original run of these region mod chips is just about sold out.  As a result, we are working on making some new region mod chips.  A few revisions are being made and also some changes to hopefully make them easier to install.
