*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;
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.
