So I posted over in the general arcade area that I picked up a large lot of pins. I am currently working on three of the tzs all lined up next to each other and before monday comes I was wondering if anyone had any good ideas as to whats going on with these pins. Keep in mind a few of them have wires hooked up wrong, but now that I have some great pictures I should be able to make sure they are correct. In all of them, I put an updated 9.4 rom in them and replaced the batteries

TZ1
Machine was stripped, everything cleaned or replaced, put back together and now has no high voltage. Also when it starts up the flasher by the slot machine plastic flashes and the sound is made like the ball was shot. this game was done by someone that helps me and is new. I know I need to go ahead and go through all the wiring etc. But let me know if you think i am on the right track. I am thinking this is a ground issue for the high voltage. Is there anything else that it could be? Is there a location I can meter to see if it is even producing high voltage?

Tz2
So this one I havent done anything but the rom and battery change. Rarely it will get past the original startup testing screen, start a game and as soon as you hit the flippers it resets. Thinking ground issue again, just creating a short. But most of the time, it goes to the testing screen and almost finishes and then just resets and starts testing again.

tz3
Goes through testing starts up and randomly turns off and resets. All different stages of the game or maybe not even get to a ponit where you can start a game.


Any heads up before monday would be great. I have a feeling its going to be a long monday. Thanks guys, this place is a great resource.
 
http://www.pinrepair.com will give you detailed information about the voltage and what to do to fix it, sounds quite possible a blown fuse.

tz2 and 3 sound like you still have some battery corrosion damage issues with the reset circuit have you pulled the boards to check the back sides? even though the front might appear ok the back might be destroyed. check it out and let us know what you think either way pinrepair will be your new bible

Items 2 and 3 certainly sound like line voltage drop to the game - this is cause of resets. Check the outlet, make sure consistantly providing the needed power.

If the outlet is good and you are getting the required juice, a very common issue with TZ - bridgerectifier gone bad causes resets. Do a google search for all the info you need (just do search for TZ pinball reset - comes up monthly on REC GAMES PINBALL board).

Considering all games have voltage related issues - maybe the receptacle is not suitable. Or, you have two machines with the same trouble at the same time (BR1 failure).
 
Example post from a TZ google search:

Sounds like the MPU is resetting due to a drop in the 5 volt line.
This is very commonly caused by bad bridge rectifiers. Also, how good
is your line voltage, that's the first thing to check, try running a
beefy extension to a different outlet and see if it still does the
same thing. If it's the rectifiers, they are easily replaced. If you
don't feel up to the job, Clive at Coin Op Cauldron does great board
repairs.
 
Thanks for the info guys. I will do a search on google about the rectifiers. As for the supply, i just built the shop a year ago, clean good voltage is there. So i know its not a supply issue. Are bridge rectifiers a major task to take on?

-This one, you may have the flasher and coil plugs mixed up. Check against the others to see if that is the case.

-Probably a bad bridge rectifier at location BR2 on the power driver board (big board in the backbox). Change the cap at C5 too while you have the board pulled. Also clean the flipper button optos and check the solenoid secondary plug (far center right of the driver board with red and blue/white wires) for any burn marks. the resistance there from a burn mark will cause a reset. Set the voltage for low line in the adjustments menu.

-Maybe same as above, but here I would check the +5v connections on the CPU and driver board (grey wires, mid right on cpu, mid left on driver) for corrosion or burns. Also reseat your grey ribbon cables.

I havent done BRs yet - it is BR2 and not 1 as i stated before. There is alot of information online on how to replace, especially at pinrepair (best site ever).

its a $5 part or so, if you can solder boards, should be a snap.
 
soldier shouldnt be an issue. wow after breifly reading a bit at pin repair it seems like there is a lot to learn about these issue. I just talked to someone that is local that works on games, usually i do everything myself, but time is kinda the issue with getting these done. what do you guys think is a fair hourly rate on this stuff. was thinking of hiring him for a few days. how long do you think that it should take for him to diagnose and fix one pin with a problem like this? i know every game is different, but maybe your guys ballpark ideas would be great. thanks
 
The pin repair site seems intimidating but they provide a step by step approach -the same the repair guy would use. I would suggest trying to get your hands around it. Otherwise, a repair hourly could be 250plus.

Another idea - get in the back box of all three games. Are there any burnt connectors ? Particurlialy around j 101 which is for power.

Another idea - you could swap driver boards - the big board lower right hand corner of tz1 into tz2 or 3 and see if you get same issue or not - try and narrow it down. We all suspect resets are caused by driver boards, so, if you have a machine that doesn't have reset issue, swap the board and see if problem persists.

Sadly you don't have a fully working game so it's tough to say. At least if you swap tz1 into 2 and have same tz1 issue you know it's the board.

If you swap and get working, then you know tz1 machine issue is not the board it's something outside that board, and perhaps tz 2 will work now. Then take tz2 board, pu

New driver boards are 300 a piece roughly.
