I recently bought an old White's COIN MASTER 2900/D Trooper at the flea market and I'm trying to fix it for my 10 year old nephew. It has some undefinable problem and it won't turn on, I have taken it apart and checked all the connections and wires. If any one knows what type of problem it is or has similar experiences any help would be appreciated.[attachment 15431 003.jpg][attachment 15430 002.jpg][attachment 15429 005.jpg][attachment 15428 004.jpg]
