Hey all you pinheads! Let me first start with a big THANKS to all of you. This site and everyone's knowledge is much appreciated and been extremely helpful!

So over the past two years I decided to do my first full restoration. I pick up a TZ that needed a good makeover. Cabinet was re done, playfield stripped and cleared. Trim powder coated. Everything cleaned. Game looks sweet. I'll post some photos later. Now on to the issues at hand.

Get everything put back together and turn game on... Only two flashers in the back left corner light and nothing else happens. Game does not boot.

Try turning game on and off a few times and third time the game boots, but the display is black.
I now flip the ribbon cable to the display at the board and display lights, but is a garbled mess.

I now decide to hit the menu button to verify that the game did actually boot. Sounds like it goes into menu system and wants date and time (keep in mind I can not see anything on garbled display).
I now hit menu button again and flippers energize and remain so.

I kill power to game as I don't want to make things worse, but being impatient I turn power back on.
Again doesn't boot. Try again... nothing. Third time it boots.

I try menu again and same results, the second time I hit the button the flippers energize and remain so. I kill the power.

So now I am asking for help and any ideas that you pinball gurus might have. Thanks in advance!

Thanks guys. Will report back.

Tested voltages and all look good. Had a ribbon cable backwards.

Game boots consistently now and dmd works.

Now onto the next stage.

When I enter the menu options both lower flippers fire.
When I backed out they went down. Game did a self test and after that two other coils are repeatedly firing.

Now what do I look for?

Just to add the flipper only release when I back completely out of menu then that when the rocket and trough start firing.

Ribbon cable is good. So it appears that the rocket switch was stuck.
The flippers were a product of adjustment as I installed the GLM flipper boards.

Now just the trough fires when I turn it on. I assume that there is another switch issue there as well.

However, why am I getting high voltage when coin door is open?

Ok so I realized that the game is looking for balls I put 6 balls in and the shooter diverter was not working, game kept kicking ball into the plunger lane. I assume that the gumball machine needs some loaded at start of game.

Checked the diverter coil and I had the wires switched

Corrected the problem and it still doesn't work. Did I fry the coil? Something on the board? Where do I start now?

Again thanks for everyone's help I feel light years ahead of where I was two days ago.

Switches are working. Last one is not getting hit by kicker, already found and fixed that.
Diverter not working in test mode. I'm getting a continuity sound when I touch the two purple/orange wires to ground braid then it quits shorty there after.

Put DMM on coil and nothing.

So transistor...Coil or both?

Yes I measured the resistance across lugs and nothing. I'll replace coil and report back.

Coil was weak. Replaced and working fine.

Now I have a switch matrix problem. Column 6 is not working. In test mode power payoff, switch 65 shows closed, rest open, but none work in test mode. Switch looks fine, not closed, and diode is good.

Checked the boards and not sure if this is an issue or related, but when I got to pin 3 of J207 I believe and jumped to pins 1-5 of J209 coils would fire. Is this normal or even related to my switch issues?

So switch problem solved. Found a broken wire leading to the first switch in the column. It was a tough little bugger to find as it was hidden in the middle if the harness.

Thanks All!
