Just received this board in the mail, which looks in good condition, and sold as 100% working. I tried reseating roms but nothing helps, it just stays like this.

I think I found the culprit -- when I apply pressure to this chip all is well.

I think it's just a cold solder joint, if I bridge the very corner of the chip leg it's fine every time.

Well we'll see how I do, next to no soldering experience, and just ordered my first gun. Can't be too hard right! : )

good find!!! surface mount chips can be a real pain to solder. Be very careful and inspect your work afterwards.

Fixed!



Honestly if it weren't for John this wouldn't have gone so smoothly, from narrowing down the problem to basic soldering. Thanks man!
