BigO Posted June 21, 2007 Share Posted June 21, 2007 (edited) I recently acquired a 5200 (2 port, if that matters) for a really good price from a fellow AtariAger. The power supply, Atari part number C018187, had a blown fuse which I replaced. Unloaded, the power supply is putting out ~14.7v which looks pretty clean on an oscilloscope. Now the 5200 powers up. On power up it only displays a blank, black screen, but the video is clean in that it doesn't jump or flicker or change colors, or do the wiggly-scrambled-missing-sync-pulse thing. Steady as a rock-no roll. With a cartridge, it displays the same as without a cartridge: blank, black screen. I cleaned and tested 4 or 5 cartridges. The only thing I see different with a cartridge installed is that it will occasionally display a blue-green, teal-ish screen briefly on startup before it goes back to displaying black. Less frequently, I get a solid white band about 2-3 inches wide down the length of left side of the screen (31" CRT) with the rest of the screen showing a similar bluish-green color. The console is connected directly to the f-connector input on the TV with the same RCA to F-connector adapter that I use with my other game consoles. I intend to do the basics: dismantle the unit, inspect and clean the cartridge slot and inspect the board for any obvious problems. I'm brand new to the 5200. I would greatly appreciate pointers as to specific things I might look for if anyone has experienced and resolved this issue. I'm looking for education. ============================================================================= Secondarily, or maybe primarily, while searching the forums for 20-30 minutes and finding nothing that seemed relevant, I hoped I'd stumble onto a single thread or sub-forum repository for symptoms and suggested possible remedies. I see common problems being posted and replied to repeatedly, so I don't think I'm the only one who has a hard time tracking down this type of information. More realistically, maybe it could be a thread that was just an index of links, with a brief description like "no video" and a link to a posting where the issue has been discussed by someone previously. Hardware Troubleshooting 101? If there is such a repository that covers the 5200 (and 2600 7800, of course), I'd certainly appreciate someone kicking me toward the right general direction.

SINGLE TOOTH Posted June 21, 2007 Share Posted June 21, 2007 I have a 2-port 5200 that displays a greenish type screen most of the time. Without a cart, it will sometimes show a black screen. Quote Link to comment Share on other sites More sharing options...
BigO Posted June 22, 2007 Author Share Posted June 22, 2007 <Yukon Cornelius>Nuthin'</Yukon Cornelius> I'll see if the 5200 forum yields anything. Quote Link to comment Share on other sites More sharing options...

BigO Posted June 30, 2007 Author Share Posted June 30, 2007 Did you ever get this problem resolved? Not yet. I have too many projects going on. Haven't gotten to this one yet. Quote Link to comment Share on other sites More sharing options...
SINGLE TOOTH Posted June 30, 2007 Share Posted June 30, 2007 Well, if you do, post the results. I have the same problem, except i have a greenish screen when a cart is inserted. Quote Link to comment Share on other sites More sharing options...
