+Stephen Moss Posted January 26, 2015 Share Posted January 26, 2015 1) Check you have soldered the regulator and Capacitor in the correct way around. 2) Check than no adjacent regulator pins other than 8, 9, 10 & 11 are connected to each other by solder 3) Check that pins 8, 9, 10, & 11 are connected together in case your problem is related to the one in thread http://atariage.com/forums/topic/219954-weird-jaguar-power-issues/?hl=%2Bjaguar+%2Bpower&do=findComment&comment=2899139 If all the above appear to be correct then 4) Check that the regulator output voltage is correct by measuring the voltage between ground and R126 (150R dropper for the power on LED) , you should get 5V at one end of the resistor. Other than that I am not sure it is a problem that can be fixed via forum posts/pm as you description does not give a lot of information that would allow pin pointing of the problem, however as you have changed the regulator and capacitor it probably has something to do with that unless whatever caused the regulator to blow (if that was the case) fried either Tom, Jerry or the BOIS chip in which case the Jag would be non recoverable.

bulldoggamer208 Posted February 20, 2015 Share Posted February 20, 2015 Does anyone know of anyone still doing Jag repairs? I'd really like to bring mine back to life, especially since I have about 10 un-played titles! Quote Link to comment Share on other sites More sharing options...
