Tron is ALIVE!!!! WAS: Tron help needed

[shilmover]

So I picked up a Tron (see here: http://forum.arcadecontrols.com/index.php?topic=83470.0), but I wanted to keep the repairs separate.  Hope that is okay.

Here is what I know:
- I have power to all the lights, monitor.
- Game does not power up.  No sound.
- No corrosion on the Power Supply board.
- The PCB was repaired as some point.
- I disconnected the Purple wire, no difference.
- Fuses appear to be good (what is the best way to test them beyond visually?  Resistance?)

A few of questions...
1.  The yellow LED on the PCB, i know that flashes when ROMs are bad, but is on on when there is power to the board?
2.  Where can I check to see that voltage is getting to the PCB?
3.  Which of the 7 fuses is for the Power Supply?

I would like to try to fix it before I replace the Power Supply board.

Update.

Just checked the voltages.

+12V is good
+5 is reading +2.91V with the battery connected and +3.20V with the battery disconnected.

Do you have the manual yet ?

TRON Manual

[shilmover]

Yup.  Found one in the Cab.  :-)

There is definitely not enough voltage heading to the PCB.  Ordered a rebuild kit from Bob.

Thanks!

Orange glow in the monitor tube neck?

[shilmover]

Yup.

Monitor is definitely firing up, PCB is not.

Figured out last night that there is not enough voltage (+5V) coming to the PCB.  Ordered a PS rebuild kit from Bob.

[shilmover]

OK.

Came back from vacation and installed the Bob Roberts kit.  Still getting only +3.29V from the Power Supply.   

Any suggestions?

[shilmover]

Woo Hoo!!!

Got Tron working this morning.

Monitor needs to be re-capped, but other than that, everything works on it.  My kids (and I) are so happy!   

Anyone have a list of the caps that need to be replaced on a Tron monitor?

There is no such thing as a "Tron monitor". Look at the monitor Chassis and find the monitor type. If in doubt, post a pic of the chassis.

You can order your cap kit from Bob Roberts for $5.

Damn!

I just placed an order with him and forgot that.

Anyone have a list of the caps from that kit?  I have a large number of caps sitting around.

The cap list is in the manual:

Sweet!  Thanks!
