PC Engine corrupted graphics issue

[policenaut]

Hi folks, it's been a while since I posted something here on pcenginefx forums; this time, I wanted to ask you guys about a problem with my PCEngine.  It's giving me garbage/corrupt graphics when I load a game on it.  I cleaned the contacts with rubbing alcohol and I don't see any improvement.  I am suspecting that one ram is damaged. 

Has anyone of you guys had a problem like this before? Thanks in advance for your response and/or suggestions!
