Magic Knight Posted March 11, 2019 Share Posted March 11, 2019 HI I (think) i managed to warp a Commando cart the other day, - i got one second hand and had a look at the pokey chip, however when i plopped it back in all i got is a white screen. (should have tested it before opening the sucker..) I have a 2600 pole position cart also that does this. Questions are - what goes zap when its pushed the wrong way round? and is it fixable....??

+-^CrossBow^- Posted March 11, 2019 Share Posted March 11, 2019 I've pushed carts in the wrong way when they were out of the case many times. Haven't killed one yet doing this though I supposed it is possible. Quote Link to comment Share on other sites More sharing options...
Magic Knight Posted March 11, 2019 Author Share Posted March 11, 2019 its strange as ive done this before also without ill effect. Ill see if its unique to the console or knackered in general. Quote Link to comment Share on other sites More sharing options...
+save2600 Posted March 11, 2019 Share Posted March 11, 2019 Warped? Pushed the wrong way around? You mean you inserted it upside down or chipside down? Seems to me you'd fry the chip doing so... Quote Link to comment Share on other sites More sharing options...
AtariBrian Posted March 11, 2019 Share Posted March 11, 2019 Did you put the pcb in upside down ? Quote Link to comment Share on other sites More sharing options...
Magic Knight Posted March 11, 2019 Author Share Posted March 11, 2019 Did you put the pcb in upside down ? Think it was placed 180- degrees, thus zapping something. it didnt have the shell on at the time Quote Link to comment Share on other sites More sharing options...
AtariBrian Posted March 11, 2019 Share Posted March 11, 2019 Ok I just wanted to make sure you tried inserting the pcb both ways into the console . Do you have De oxit ? Quote Link to comment Share on other sites More sharing options...
Magic Knight Posted March 11, 2019 Author Share Posted March 11, 2019 (edited) No but I have rubbing alchohol. I'm guessing oxidisation has may be occurred and cleaning the contacts is the first step? Edited March 11, 2019 by Magic Knight Quote Link to comment Share on other sites More sharing options...
AtariBrian Posted March 11, 2019 Share Posted March 11, 2019 No but I have rubbing alchohol. I'm guessing oxidisation has may be occurred and cleaning the contacts is the first step? At times I have had success with De oxit . After trying with rubbing alcohol the games still didn't work so I tried De oxit and they finally worked . Normally though rubbing alcohol does the job . 1 Quote Link to comment Share on other sites More sharing options...
Magic Knight Posted March 11, 2019 Author Share Posted March 11, 2019 Ill give it a shot. Might be my console also. I've got 2 pal 7800s so I'll compare the two. Quote Link to comment Share on other sites More sharing options...
Shawn Posted March 11, 2019 Share Posted March 11, 2019 Think it was placed 180- degrees, thus zapping something. it didnt have the shell on at the time Ya if you put the cartridge pcb in backwards that could have ill effects for sure. First thing you can check is the voltage regulator. If you get lucky you might have just popped that only. Worst case you could have fried the POKEY in that cart as well as they are not able to take much misuse without breaking. I say that from personal experience frying pokey chips on 5200 machines. 1 Quote Link to comment Share on other sites More sharing options...
Magic Knight Posted March 11, 2019 Author Share Posted March 11, 2019 (edited) Thanks, no harm in getting one in to try (regulator). I got the 2600 pole position to work after cleaning contacts with IPA but commando still white screen.
