1. You appear to have a bad Triac (EDIT: SCR) on the Lamp Driver Board.
2. Only you can answer that one.

To help; Can you solder electronic components? Can you read a schematic diagram of a circuit board? Can you read a basic wiring diagram? If yes to all three, Iā€™d say you can.

Triac? And yes to all the other questions

I linked the game for this topic , on that link I go over to the "IPDB" page http://www.ipdb.org/machine.cgi?id=4501 and there is a lamp driver board schematic there. (also a full set of schematics)

looks like the SCR is "Q3" on the lamp driver board from the shoot again in the backbox

keep us posted
