ajw85 Posted December 30, 2016 Share Posted December 30, 2016 I was recently given this O2 from a family member. I hooked it up and used a SNES RF adapter to get it to display on my TV. When it is powered on, I get a grey-ish screen with a few garbled letters and numbers. Any idea if this unit can be repaired? Any hints before I rip it open? https://goo.gl/photos/higwtsnwsiJeJyPW9 Quote Link to comment Share on other sites More sharing options...
+grips03 Posted December 30, 2016 Share Posted December 30, 2016 do you have cart in the slot? Quote Link to comment Share on other sites More sharing options...
metarog Posted December 31, 2016 Share Posted December 31, 2016 Here are a few things you can try... Clean the contacts on the cart connector and the game(s) with some rubbing alcohol and cotton swab. You can use an old toothbrush on the connector. If no improvement and you tried several games open up the console and check to see if there is any corrosion or broken traces on the board. Also check the connector pins for continuity to the various chips and power sources. If all the that is good you probably have a bad 8048 chip. It is a sensitive chip so check the power rail from the voltage regulator to the chip and see if you are getting 5 volts. If so you can just replace the chip-if you can find one. If the power is wrong it would probably be easier to find another O2. Keep us updated and the SNES RF switch will only get you a grainy picture so if it does work you can always AV mod the O2.

+atari2600land Posted December 31, 2016 Share Posted December 31, 2016 (edited) I get this sometimes too. Have you tried pressing RESET (the red key on the keypad with a triangle on it) a few times?
