My husband friend the WhiteWater... We did the lithium conversion to the battery- he tested it before screwing the board all the way in, it worked.... then- THEN... a screw fell out... he picked it up and put it in the wrong hole - (Near the hole by j202) He shorted the machine replaced fuses F105, F106- and we got verticle lines on the DMD and we lost music and voice... Pulled the boards - took pictures looked them over... put everything back in and had nothing, no power past the Power controller board (LED 7 lit) and the Topper chaser board (2 leds of some # lit) THEN J101 MELTED!!! Aaaaahhhhhhhhhh
