when i hit a pad the light goes on but its half as bright as normal, it seems to go back and forth with the brightness.. fully lighting up half the time, otherwise a dull light. this problem is with all the pads.. i've tried different adapters, memory cards, and reformatted. is it just on its way out? i'd buy another one in a heartbeat..the 303 is my whole game, just wondering if anyone has experienced this problem. I really appreciate any advice, thank you!

Was gonna say maybe the LED is failing but if it's on all the pads then sounds more like a power issue. Maybe try a different power adapter? I know you rock several 303s so I guess you have another one!

Just realised you've tried a different adaptor so ignore my previous ramblings!
