Thunder Force AC repair

After a long break from board repair I finally got the ball rolling again with this Thunder Force AC conversion pcb I just picked up. It was sold as having issues with the background graphics and that was exactly how it behaved for me too. The background would constantly flicker, everything else seemed fine.

On close inspection of the pcb I found a few issues, there were a couple of small patches of corrosion. Most of it just needed cleaning but one spot it had gotten as far as eating through one of the traces.


I tinned all the traces in the area where there was corrosion and added a tiny bit of wire to the broken trace.


Then finished it off with a small amount of liquid solder mask. This fixed the background issue, all that was left to do was replace a broken resistor.






Repair complete.
