ok guys strap in for this one, I have a lost world that wont boot with the door closed.... crack the head 2-3" and itll boot fine....... with door harness unplugged does the same, all displays unplugged does the same, with all plugs removed from the MPU except for the power plug lower left it does the same...... NOTHING on that harness moves when the door is opened that tiny bit but it still does it.... On lower left of the MPU male and female of that plug was changed .... still does it ....With absolutley NOTHING on the board plugged in and it still not booting with the door closede I figured it MUST be EMF from the hi V harness going to the displays...... Made a shield with a packing envelope filled with foil to completely cover the front of the MPU....STILL wont boot with door completely closed.... you can wiggle and jiggle all the harnesses you want with the door open itll boot EVERY time ...close the door the last 2" and it wont..get it to boot with the door open and you can close it and play a game no probs..I had this prob once before on an 8 ball, i ended up wiring a momentary button across the reset line of the mpu to force reset and it would be ok ... turn the game on hit the button ad it would boot.......I can do that to this one too but wanna fix it right. WHY WHY WHY will this not boot with the last few inches of the door closed..the harnesses that do felx are not even hooked up ..power harness dont even move a smidge when the doors closing.. anyone who can figure this one out I will see to it you get the "nobel pinball prize".........the easy fix is an altek ..... but because i encountered this 2x now i want to find the exact cause.....this ones a head banger
