Hello all,
Owned the game for a couple hours- got one of these once in a life time deals. 3 games: STTNG, JP, and Batman Forever for $5k.I was only interested in the STTNG ,and sold the other 2 games to friends the same day for 2200 each. I am now fixing up the game I sold my friend.It started with an intermittent right flipper.This turned out to be the L1 IC chip.Installed socket and 14 pin chip and back in business. From there -replaced all 3 skirts on the pop bumpers. Replaced all rubbers- some in the pop area were 1/2 the thickness of the new rubber. I found several of the fuses to be too large- so I really recommend looking at this for any second hand game.Also the CN8 header pins on the power supply board were gone- replaced by a couple mountains of solder for the lighting power and returns-someone had used spade crimp terminals and all the connections were scorched. It was easily fixed with new 9 pin header.Lastly installed Cliffy protectors for the 3 scoops.
Think I found one more issue - and that might be the ramp exit switch must not be getting activated- as I have yet to see Mr.DNA. I am not that familiar with DE diagnostics- but I think the game only reports a stuck-on switch. I will try activating the switch with a ball and see if it registers. I only found out about the Ramp Molecules by reading the manual.

Reading further in the manual I see that there was an addendum for Dino Update Kit- looks like this game is operating on version 4.04. I see that version 5.13 is available for the CPU and also newer versions for display and sound.I guess my question to this group is: Is it there significant change in gameplay by the installing newest EPROMS? Also there is mention of a new crank arm as part of this upgrade- is this part readily available?

Yes- that was all it was. The exit switch at the top of the ramp was not registering- the screw holding it down to the ramp was loose and in a position to not have the ball activate the switch. I had removed the ramp for access to the pops and just had not secured it properly. It was exactly as scootss had said 3 times and hit the bunker to collect.With the switch working now- i see the diverter in play. i had not seen it activated prior.Thanks.

Quoted from evileye:

Yes, Matt’s Basement Arcade. A must have.

Thanks for this- ordered today. I tried to find a friend with a EPROM burner, but it looks like I am too excited to upgrade this game.

I have been having a blast with this game- and the right flipper failed again. So I reasoned that there must be a bad diode either on the coil or on the flipper board that is bad that is corrupting the IC chip on the flipper board. Sure enough- the diode on the coil was the culprit. Back in business, and anxiously awaiting the 2 EPROMS. Thanks again .

Eproms delivered - thanks Matt's Basement Arcade.

This burned connection is power and returns for the 4 lighting circuits for the game. Very common for most games to have heat on these connections and the problem gets worst with arcing at the connections. I have used IDC connectors, but have much more confidence in the trifurcon crimp connectors and housings.
