I was able to pickup a Virtual Boy the other day that included battery pack, controller, Wario land and headset. Sadly upon arriving at home the system does not power on at all. Upon further inspection i pulled out my handy dandy voltage meter, coming from the battery pack was the 9.8 volts. coming from pins 5 and 6 on the controller was also 9.8 volts, sometimes dips to 8.9 but stables none the less. I decided to open the unit, which thankfully was never opened before. Quick inspection al caps and internally components looked great. Reading other forums stated test the U8 DC-DC-VUE. i quickly noticed pins 1 and 2 only had .8 – 1.2 volts and then on pins 5 and 6 had .002. Clearly the issue is lying with the stepdown controller.
I am not seeing much documentation if any at all on how to repair this problem or work around solutions. easy enough to desolder and replace but seems parts don’t exist for this. Sadly buying any extra parts for these are not cheap, even if i went to the AC adapter route.
Any help and or thoughts on how to fix or bypass? thank you in advance.
