Man, I agreed with winteriscoming about Q27. I personally would have started with that also. oh well, you are up and running!!!!!

So I got game up and running, no errors. Only thing occurring is that the trex isn’t snatching up the ball. He goes down and doesn’t close the mouth, but when up chomps fine. Also tests fine. Any ideas? If I just just take glass of and move trex around it works for a bit then same thing.

It could be an issue with the switch for the saucer in front of the t-rex. If the t-rex knocks the ball slightly on the way down, it may be letting up on the saucer switch and it might cause it to assume the ball jumped out, so it doesn't bite.

You could probably test for this in switch test - get to the test for the saucer, put a ball in, slightly knock the ball towards you and see how the switch registers.

You could also start a game and keep placing balls in the saucer for several pickup attempt to see if the t-rex is knocking it on the way down.

Another potential is flaky wiring such that when the t-rex bends forward, it causes a break in the wiring that is closed when the t-rex is up. You can test for that in t-rex diagnostics. Make the t-rex bend forward until the down switch is active and then trigger the jaw to see if it's working in the down position.

JP did not have it

You can also see in the youtube chanel of vpcabs pinball he recently unboxed a JP realy cool!

Starting to build a collection of my custom mods, so thought I would put them all together in one link. You can see everything I have available here: http://www.thezumwaltfamily.com/jppinball, and just PM if you would like to purchase anything at anytime.

Just got to my second shutdown ever (my score was still bad, however). Fun thing when it happens.

BTW, I don't understand how to set the extra ball score. Can someone please explain the steps?

Do you mean setting the score for when you get a free game?

Maybe. I have mine set to award a free ball instead of a game.

Should my J.P. be shooting balls out of the shooting lane into the pop bumpers every time? Or is it normal for it to miss occasionally? I replaced the bracket and gate, but have been getting the same results. It happens about once out of every 10 times.

Mr_Tantrum You will need to go into the Audit & Adjustment functions. Go past the last one, (#12 Expand Audits) to get to Adjustments. From there, you'll want to look at #4 Game Awards (Factory set to Credit). Hit start to switch from Credit to Extra Ball.

Yes. Mine never misses.

Wonder why mine does not?

Yes, I have done this. But how do I set the score at which an extra ball is awarded? It's weird in that it seems to change from game to game right now.

Check the white rubber tip that is on your plunger. My launched balls started missing and I quickly figured out that the white rubber tip was coming loose and not fully seated on the shaft. I put a little double-sided tape on the shaft, reseated the rubber tip, and the ball upon launch hasn't failed to enter the pop section since.

If it changes from game to game, check adjustment 16. Sound like Replay Boost is set to YES.

Also, take a look here https://www.vpforums.org/index.php?app=tutorials&article=59

You were correct, I set #16 to no. That seemed to do the trick, now free ball is at the level set instead of randomly changing. Thanks.

Received my ball trough opto board from Davi yesterday, and since I didn't have anything better to do today I decided to take on the installation project.

First, I needed to trace a wire that a previous owner had installed and was connected to one of the switches. It went all the way from the white wire lead on switch 2, up through the backbox, and was spliced into the color wire for the same switch there. Long story short, I removed the wire, tested continuity on the original wire, and everything was good. I have no idea why somebody would bypass a perfectly good wire. Onto the opto board . . .

1) First thing I did was to tin all of the leads on the opto board (very crucial to do this before you install)
2) I already had a 12V supply coming from alternate source, so I hooked a wire into it - positive and ground (I used the dual wire I recovered from the no longer needed switch bypass), and with playfield lifted ran the wire through the cable management on the underside of the playfield up to where it would reach the opto board
3) Turned on pin and put a meter on the end of the newly installed wire to test for 12V (I was good), then turned off pin and lowered playfield to where braces were resting on lock bar area (i.e. end of playfield was slightly elevated and extended beyond the cabinet)
4) Put pin in service mode and ejected all 6 balls then turn pinned off
5) De-soldered all wires from 6 trough switches
6) Removed both screws from all switches to remove them (set two aside to use for mounting opto board)
7) Mounted opto board with backing in place (3D printed protector that came with the board) using 2 screws taken from removed switches (opto board mounting holes aligned with two of the existing threaded bracket holes)
8) Soldiered power wire to power pads on board (made sure neutral and positive were correct)
9) Turned power on to insure power was going to opto board (it was) and turned back off
10) Soldiered green/white pairs to appropriate station on the board
11) Turned on pin and manually tested optos, making slight adjustments where needed then turned off pin
12) Lowered playfield completely, powered on, and played a game
13) Success!

Davi's trough opto board survived the weekend at MGC. Not that I had any doubts, just want to help anyone who may doubt it's durability.

I've got one of the opto boards on the way from Davi. What was the shipping time for those in the US and did it require a signature?

Not long at all. Maybe a couple weeks? No signature.

Quite fast. A week or two tops from what I recall. I was worried that the board would not arrive in time for MGC but it can a week or so beforehand.

It was crazy fast - shipped 4/11 and received 4/16. It did require a signature (at least I watched my wife sign for it on our security camera).

Wow, great summary, thank you!

Good to hear, thanks for this test!

Got mine today. To answer your question differently Winter, yes, you may need to sign for it. I got a slip in my mailbox that said it needed a signature. I signed the slip and said to leave in the mailbox. Got the opto board today.

Need to get the 12v source figured out, and will be installing it. Might try to do it the following weekend.

I think that's when mine shipped or maybe the day before. Does your tracking number work on USPS? It's not showing as a valid number for them, and the Magyar Posta tracking site shows no activity since the 11th.

I'm not overly concerned about the shipping time. I'm mainly hoping it arrives before I head out of town if it requires a signature.

Don't worry, yours will show up this week.
Woody24's tracking number still at 'Handover for international transport' status - same as yours.
This tracking system is strange, and visible until the Hungarian border only, then God knows, what's going on after

Mine was same with last activity showing 4/11, and was not able to figure out how to track after that. Not sure who delivered it, but since I live in DFW (an international flight hub) maybe mine arrived a day or two before yours will.

FYI, I just grabbed packaging out of trash, and it did say on it "signature required".

Ive had luck just leaving a post-it with a note to leave and my sigurature if I'm expecting a package that may require one.

Also, I signed up for USPS Informed Delivery last week. Its a cool service where they send you an email with the photos of the pieces of mail youre going to get for that day. This package wasn't included in that list. Not sure why. Others have been.

I'm pretty sure Newman is my postal service driver. He once left an undeliverable note cause the "gate was closed". To this day, I have never seen a gate at my driveway.

My wife just said it was our regular USPS guy that delivered.

Ha! 2 weeks ago I had a delivery from Amazon. Around here Amazon has their own "Uber" type of service for delivering their packages. I got a notice that the package had been delivered, and it was "handed directly to the resident." Wasn't me. I look outside, and don't see anything on my doorstep. I started wondering which of my neighbors he delivered it to. Then I check, it was in the mailbox.

We have the same for most Amazon deliveries except the take a picture of the package although I've never had one handed to me.

that photo came in handy too. Had a packaged delivered to a neighbor's house by accident. Was able to use the photo to tell which neighbor had it.

I checked the white rubber tip. It seems good. Thank you for the insight. Someone else had posted that you can adjust the metal scoop at the end of the shooting lane. Apparently it has slotted holes in it. The ball was hitting the top of the gate and/or hitting the yellow target by it. I adjusted it all the way down. Getting a pretty good percentage going into the pop bumpers now, but still not 100%

You can also check to make sure the whole auto launch assembly (mounting bracket) is not loose, that could cause an inconsistant launch.

mine made it in 4 days from time of him sending me the tracking number. stupid fast

yes sig was required. mail lady woke my slipping kids up from nap. which lead to a "WTF did you buy now" text from wifey...

I ended up having to take out a screw to get the metal ball diverter to align at an angle that would work. It's still weird in my mind because it worked great before I shopped it out, after shopping, missed a lot. here's my old post and fix

Who here has removed their side rails for painting or replacement before? Just wondering how difficult it was on this pin and if there are any tips or tricks I need to know before attempting.

Also, what type of tape/adhesive did you use to replace them?

For those with PinSound+ boards in their JP's -- did you all also install the DE Power Booster when you did your install?

The install video on their website doesn't mention it at all for this board, but did come inside the full DE pin sound package so I installed it with the board.... that's fine right?

Yes. I did install the power booster. Works fine.

Thanks Pinbear

Just finished a deep cleaning and minor restoration on my playfield. I decided to add a few extra items, like palm trees, Jeep, pteranodons, raptor, Titan rubbers, and Comet LEDs. I know some people either like or hate some of those “mods”, but for now I’m enjoying the added dimension. And if for any reason I, or the next owner, wants to remove any of them it’s as easy as unscrewing a nut.

I’m still wanting to backlight the “when dinos rules the earth” and backdrop plastics, but that will be at a later time.

It was also my first time flame polishing a plastic ramp and I was very pleased with how the ramp and subway turned out. Pretty much came out crystal clear.

Here are some before, during, and after pictures.

Much better, nice job.

Just got my custom apron cards from @mikonos. Great quality, price, and communication. The chrome vinyl they are printed on give them a foil pokemon card type of effect. They have a nice UV resistant coating. They feel really durable. I got them in just in time for a party my wife was throwing last night. Got a lot of compliments on them. No one ever even noticed the stock set.

Hey Guys
Hope everyone is having lots of fun with the JPs

I was playing mine today and right flipper went dead !

Anyway the little metal cylinder that was in the flipper link fell out ( pic for demonstration)
Can anyone tell me where i can get a new part to link this to the arm ?

Happy Easter and Passover !

Lol i didnt want the party to stop so i cut a nail and slipped it in with the head up for now

It's called a roll pin - don't remember the size, but it should be in the bottom of the machine. Take it to a hardware store - they may have the right size to replace it.

Thanks hope home depot carries them
