Replacement cap for Frenzy ZPU1001 board

Tonight I stopped after the gym at Radio Shack to get a replacement capacitor for the ZPU1001 board. I didn’t want to travel all the way to Meunier for one cap. I soldered it in and put the board back into the cabinet and got….nothing.

I got a white screen again, which was quite disappointing. The board was dry from the scrubbing, there was no reason it shouldn’t work. But, I did also have some problems soldering, the iron I have is about shot (which is fine because it was free). I don’t know what a cold solder joint is, but maybe that is what happened. Is a cold solder joint when you have old solder with new solder on top and the electricity doesn’t flow between them? All I do know is until I took that board out and scrubbed it and replaced that cap, I at least had garbage on the screen.

Here is what I expected to see like the first time, the Frenzy garbage on screen.
