Javaman Posted August 25, 2016 Share Posted August 25, 2016 I have this pong console that works fine but I've noticed these thin evenly spaced vertical lines. They're present on all games, channel 3 or 4 and they never move. If anyone has this same console could you check to see if this is normal or not? I'm wondering if there might be a faulty cap but really not sure. Thanks. Quote Link to comment Share on other sites More sharing options...

Javaman Posted August 27, 2016 Author Share Posted August 27, 2016 (edited) I did some searching on the game chip MM57100N and ran across a few screen grabs showing the same vertical lines even with different consoles so I guess it's normal for the ones that use this chip. Still kind of curious to know what causes it. There's a japanese site with what looks like a custom homemade version using the same game chip and LM1889N modulator chip packaged into a clear box with video & audio composite outputs. Same vertical lines even with composite. http://www.ne.jp/asahi/shared/o-family/ElecRoom/ElecGame/MM57100N/MM57100N.html Edited August 27, 2016 by Javaman Quote Link to comment Share on other sites More sharing options...
