Hi people This is my first post here on Pinside!
I`m having some trouble with my dear Star Trek-TNG machine.

Issue 1:
When i start it up it says check fuses F114 and F115. I did this and F114 was blown.
Tried again with new fuses a couple of times, and it blew right away each time.
When this happens the ball popper ( left side on the playfield ) is constantly popping like crazy, however i dont think this happened the first times the fuse blew.

Issue 2:
I`m also having trouble lifting the playfield all the way up, i think it is because the slide-latch on the right is angled slightly downward ( !) and because of this; is not connecting up with the "rods".
Check attached images for visual reference.

Anybody seen this before? Any tips on how to proceed?

Any help from the Wizards here would be greatly appreciated

Best regards

1. You must have a short with the ordered lamps. Check with the DMM the continuity.
2. Oops, I would lift the pf and reseat it, or remove the metallic part first, if you cannot do it straight.

Many thanks for the advice and the info

Btw, just found out that "Bridge Rectifier 1" is dead.
I guess this means i will have to replace BR1 and BR2 since the heatsink connects to both.

Any advice on how to proceed from here?
Is it DIY?
Any tips on where to buy ideal replacement BR`s?
