Quoted from Pinballomatic:

As it relates to the start button getting stuck, sometimes the playfield doesn't sit level and can actually catch the back of the start button housing if everything is just so. Pull the playfield forward and flip up, make sure the start button is oriented correctly and that it is sitting flush inside the housing. With the playfield up, correct the start button and make sure it's not askew and works smoothly. Then as you lower the field to put the tabs in the slots, make sure it doesn't try to rest on the button housing. The tolerance there is a bit too close. Just take it slow and all will be well.

Quoted from finman2000:

Did you figure out what the plastic piece is for? I had the same problem.

Quoted from PinMonk:

I had the same problem with the start button. The bulb is too big (slightly). Unhook the switch (it twists to the side about 20 degrees), take it out, put the switch back, and the button works fine. I intend to sand the sides of the bulb top area and try it again. It's just *barely* too wide.

Quoted from finman2000:

What kind of sound issues are you having? I was getting static in the right speaker. Issue was the 3.5mm aux. cable between the motherboard and the sound board was bad. The cable they use is cheap. I used one I had on hand and that resolved my issue.

Quoted from finman2000:

I think you are having the same problem I did. If you have a spare 3.5mm cord try that. It should be the cable that connects from the pink plug on the inside of the metal case on the sound board to the green plug on the outside of the metal case that is actual the computer motherboard(MSI)

Quoted from crwjumper:

That piece uses the gray stickey strip to attach directly underneath the writing on the ramps. The strip is situated directly between the Optos, and sticks to the underside of the ramp. It is used to diffuse the light that is used to light up the words on the ramp. If you look closely you'll see that most likely one ramp has this and one is missing.

Quoted from Rom:

I give up atm on the Hobbit. Beast head fell off because it was barely attached with only one screw. Another beast is not registering any more because the cables from the switch of the head were chopped off because they touched the upper trapped ball fix every time they raise. I also spotted another beast with the cables halfway chopped already caused by the same issue. Mine came with the ball trapped fixes already installed. So not caused by me.
Recap:
-many missing screws on various parts (fixed it already)
-cables pinched between screws that go into the wood (fixed it already)
-speakers popping & crackling (still needs to be solved somehow)
-unplayable since beasts not reigistering any more (needs to be addressed)
-lockbar not closing unless you force it (needs to be addressed)
-beast head barely attached with one screw, second screw was non-existant (fixed it already)
-headphone jack not working at all (needs to be addressed)
-to take the invisiglass off it takes forces that can't possibly be meant like that.
Since I have it i was not able to play more than 1 game without having to open it and fix something / looking for sources of problems.
Well that is not the experience I had in mind when purchasing a more than 9000 Euros NIB machine.

Quoted from ls1chris:

Anyone else have clearance issues with the left sling axe hitting the PF? At the end of stroke mine hits the Pf , the mech looks more inward then the right side

Quoted from Hammerhead:

I'll be having a league night at my house in a few weeks. Many members have insisted that Hobbit be in the rotation, but I'm reluctant because of the long ball times.
I'm too lazy to read through 11 pages of posts; does anyone have any suggestions about setting up Hobbit for league play? Some things I will be doing:
- set the pitch to 7 degrees
- remove the centre post
- open up the outlanes
Are there any settings that can be manipulated to keep ball times relatively short (+/-5 minutes)?
