Keatah Posted January 25, 2016 Share Posted January 25, 2016 Looks pretty much like digital noise. Quote Link to comment Share on other sites More sharing options...

CatPix Posted January 25, 2016 Share Posted January 25, 2016 Does that fuzziness appears in game as well? Does it appears on different TVs? Quote Link to comment Share on other sites More sharing options...
drummer4261900 Posted January 25, 2016 Author Share Posted January 25, 2016 Does that fuzziness appears in game as well? Yes Does it appears on different TVs? Yes I just tried it with another 1080p TV. Quote Link to comment Share on other sites More sharing options...
Reaperman Posted January 25, 2016 Share Posted January 25, 2016 at least yours still produces a fuzzy signal. It could be worse. I have one that doesn't. And no, you don't want to trade. Quote Link to comment Share on other sites More sharing options...
+save2600 Posted January 25, 2016 Share Posted January 25, 2016 Video chip partially fried? Could always try reseating all the I.C.'s and see if that clears it up. Does it happen right away, when you fist turn on the system? I've seen vids where people experience strange video artifacts after the system has been on for a while. Need to glue some tiny heatsinks onto some of those chips. The Bally "professional" arcade is notorious for its heat related problems.

drummer4261900 Posted January 25, 2016 Author Share Posted January 25, 2016 (edited) Does it happen right away, when you fist turn on the system? Yes The picture is the only problem. You can still see fine when you play a game its contained to just the top and bottom. The sound works.

HoshiChiri Posted January 28, 2016 Share Posted January 28, 2016 (edited) Have you tried connecting to a non-HD TV? You could just be seeing edges you're not supposed to due to the larger display (something I noticed on my Atari when I got my HDTV.)

Keatah Posted January 28, 2016 Share Posted January 28, 2016 Looks like the text and noise are too close together. The noise area should be a solid red. Check all the chips, clean and reseat them. Inspect all solder joints. Check heatsinks. Clean switches, connectors, and contacts. This is standard preliminary stuff when working on old stuff. If that doesn't fix it you'll have to start swapping chips one by one, or break out the schematics and start some real electronics troubleshooting. What else is there to do? When someone says/thinks it's chip X and the problem still remains, well, you've just begun the blind-swapping process. Quote Link to comment Share on other sites More sharing options...
+stupus Posted January 28, 2016 Share Posted January 28, 2016 I assume you of course aren't using a rf switchbox, correct? Quote Link to comment Share on other sites More sharing options...
iesposta Posted February 21, 2016 Share Posted February 21, 2016 All great advice, but remember we are talking Bally Arcade / Astrovision. They can die by looking at them. I STRONGLY recommend (as does its service documents) first grounding yourself, opening and if removing a metal shield don't let it touch any components. Next short the large capacitors. This is all documented in its official service pages! Looks like the text and noise are too close together. The noise area should be a solid red. Check all the chips, clean and reseat them.

128Kgames Posted February 21, 2016 Share Posted February 21, 2016 They can die by looking at them. Blasphemy! Completely untrue! You cannot kill one of these consoles just by looking at them! Now, if you stare at it intently for more than sixty seconds, it could quite literally burst into flames. Or not. On a more serious note, drummer4261900 I know you had posted this issue on the Bally forum as well but cannot remember if you had tried a non-HDTV (such as HoshiChiri) suggested? Or more specific have you tried a non-LCD TV (tube, plasma etc.). 1 Quote Link to comment Share on other sites More sharing options...
