Hello all.

My Tron upright just went dead.

Looking for a bit of direction - I'm a rookie, so any help will be GREATLY appreciated.

The machine is TOTALLY dead. No sound, no neck glow, no buzz, nada.

It is getting power - and I have verified that the TWO safety switched are closed.

There is a single power socket on the main PSU board and if I plug something into that
socket I DO get power there.

There is NO LED glow on the main CPU board.

Looking for some "starting" points

Also, are there any links to Tron Schematics? Specifically the power related stuff

Much appreciated,

so you are fairly certain the monitor isn't getting power? does the game play blind? (can you hear it playing)?

I would start with the fuses in the bottom on the big power brick in the bottom of the cab.
make sure the game is unplugged and pull each fuse and test them with a meter.

I have had my tron 'play dead' when the bottom back door was locked shut but not pushed in enough.
 
Thx Tron Guy

I will double check the fuses - at first glance they seem ok.....

I made sure the two buttons on the back were fully depressed - still nothing
 
Sounds like a disconnect from the AC wire coming off the wall to the power in the cab. As i recall, on the big brick at the botton, the left side Molex (larger ones) power the game boardss (sends the voltage to the power supply board on the left side of the cab) and the right side molex on that power brick goes off to the lights and perhaps monitor.

In anycase, those two sound like they are NOT getting juice (otherwise, you would at least have lights / have power to the PS which supplies power to the boards) - so you can say you have isolated the problem - to between the AC wire over to those molexes.

Whats in between those? The Fuses, AC line filter (i think these are in there), big caps.

Pull the fuses on that brick and check them - get a mulitmeter, set to continiuty mode and check each one - you are looking for the buzz. No buzz and you found one problem.

Let us know how it goes!

+1. I spent a fair amount of time (wasted time) on my Centipede until I tested the fuses and saw that one went bad with no visible indications.
 
Have the same "totally dead" thing happening with my new Tron. Will be keeping an eye on this thread. Thanks for the info everyone!
 
for the record, it doesn't matter how a fuse looks, you need to test it.
 
Thanks to Tron Guy, Jon and other for the "tips"

will be doing much testing tomorrow and report back

Much appreciated guys!!

On the safety switches.. they are designed to be pulled out to an 'on' position when the door is not in place. Just pull the plunger until it clicks into place. They go back easy when you put the door back on.

Look forward to what you find. My SW cockpit did the same thing you mentioned, i drove myself nuts looking for it on the boards and such, only to think it through, and trace it down to one fuse that "looked good" but really not upon closer inspection. I replaced that many moons ago, and it works fine now.
 
Tron Lives!!

Tron is BACK!!

After much poking and testing it turns out it WAS a fuse.

It was the 250V 3amp "slow blow" fuse near the bottom on the power block

Closest to the back of the unit, near the power cord, there are two fuses

It was the 2nd one.

"looked" good but it tested bad.

Replaced it and Tron fired right up.

Thanks to ALL here for your help and support

Much appreciated
