| Wonderboy bootleg jama distorted graphics |
| (1/1) |
| telonio:
I have a Wonderboy bootleg 2 layer pcb and as you can see in the photograph, usually it shows distorted graphics. Now when I move the pcb slightly, the graphics are fixed. So I guess that there must be some cold solder joints somewhere, but where? https://i.postimg.cc/GhwvYTNX/20210711-143332.jpg Thanks, |

Get a magnifying glass and look for the cold joint? Push on individual chips and see if the image distorts. |

Unseat and reseat the socketed chips. |
