So I picked up a Tron (see here: http://forum.arcadecontrols.com/index.php?topic=83470.0 (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 (http://arcarc.xmission.com/PDF_Arcade_Bally_Midway/Tron_Parts_and_Operating_Manual_(July_1982).pdf)

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?
-
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.
-
OK.
Came back from vacation and installed the Bob Roberts kit. Still getting only +3.29V from the Power Supply. :dizzy:
Any suggestions?
-
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! :D
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.

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:
