Jurassic Park
Data East, 1993A good clean and wax is all that is left to do! I am swapping out the power supply board for one I'm freshening up on the bench but that is a five minute job I can do in place once completed.
And the topper sign, I'm printing out some samples this morning for trial.

What did you use for your t-rex teeth? it kinda looks like that thin white foam you can get in sheets.

My wife is lactose intolerant, a jug from her fake milk worked awesome and it was free.

Quoted from wolffcub:My wife is not lactose intolerant so i will have to look for another solution.
There are other products that use the same style solid white plastic, bleach bottles for example.

That's alot of bleach to drink before I can use the empty bottle. I will clean out the fridge later and see what i can possibly find.

Next time at store look for one of these small lunchbox milks.

Funny you mentioned that. After my post I already started drawing cut files to cut them from white abs on a laser table.

Ha, I still have 98% of the jug left, was going to offer to send a piece if you need it.
Quoted from edward472:What?!? Like out of nowhere?
Yup. Popped a diode on the board and allowed high voltage to cross over to the low side. I replaced the diode which brought the display back up but the damage is already done. I think it took out one of the surface mount chips.

Just a follow up on the DMD issue, I think I figured out what happened.
Going through some documentation, DE issued a technical service bulletin #38 update to the Power Board schematic. Seems like there was a misprint and some diode locations (D10/D11) were mislabeled. Care to guess what diodes got replaced on a board I was rebuilding and testing? Yup.
So if you have a factory service manual for LW3, Rocky and Bullwinkle and Star Wars pay close attention to the board revision and what is actually on the board for parts.

Man. What are the odds?!?!
Quoted from edward472:Man. What are the odds?!?!
Most unfortunate, there might have been a reason the board I was working on was missing the D10 diode when I started on it. I think someone already tried replacing it and went by the schematic.
That lesson cost me $100 for a replacement DMD, ching! ching!
