Hello. I recently replaced all 11 capacitors for my sega game gear in addition to 5 capacitors on the sound board. Once complete, I tested it out. The game gear was like new with volume working and contrast adjusting properly. After a minute, the screen began to dim and the sound was all that was left. I immediately turned it off and then back on. The sound was all I could hear. After a few more times turning it on and off, the system began to turn itself off after only 1 second. The screen will appear white while the red power indicator light is on. Has anyone else run into this problem? Did I not solder properly? Any suggestions are greatly appreciated.
