In my TZ, the lower left field had the GI lights out, I had investigated the GI connectors and found them to burnt so I got some replacement headers and connectors. Last night I got around to working on it and pulled out the board to replace the headers.
After soldering the headers back in I checked the continuity along the trace from the pin, it wasn't great but the DMM did beep (It wasn't great because I would not instantly find a path, had to move it around a bit)
I don't have any pictures of the solder job I did but it looked alright to me(I have no experience so my opinion here is worthless), I can post a picture later tonight if need be.
So I put the board back in and just to make sure I didn't screw that step up I plugged everything back in without replacing the connectors first. I turned it on and everything lit up, including the part that was burnt out last time. Yay!
Then the game ran its tests and I got the infamous: "Check fuses F115 and F116, J112 and Opto 12v power supply"
It was getting pretty late at this point so I only tested the fuses(I pulled the fuses and checked the continuity, they were ok) and then went to bed, when I come at this problem tonight, what should be the first thing I do? Do I have to desolder the pins and re-do it?
If diagnosing this problem requires anything more than checking a diode, please be descriptive in how I can do it, I am not very proficient with the DMM and have only used the continuity setting. In other words please talk to me like I am a 10 year old.
I appreciate any help.
