First off, the DMD is out, so I do not know if there is any error message displayed.

When I power the game on, no activity other than I hear it power on and the normal slight hum. Went through all the troubleshooting steps here :

These are my findings:

Power board:

LED 7 = off

TP1 (12vu) = no reading

BR5 - one leg reads at over 900, all other legs in the 490 range and solid.

CPU Board:

LEDs D19 on, D20 off, D21 on (normal operation is off, flashing, on)

Can I conclude that BR5 is the culprit? If not, what else can I test that I may have missed?

Thanks.

Bump so I can place an order this weekend.

No startup sound.

By normal operation I'm just stating what the manual says should be happening after the game is powered on. I have another T2 that I can compare with and on that machine D19 is off, D20 is flashing and D21 is on.

On the T2 I'm having issues with, D19 stays on, D21 is off and D21 is on.

What exactly is a blanking problem? I saw mention of blanking in the manual and thought it was a typo that should've said "blinking"

Edit- reading about it here.

But isn't the fact I don't have 12v also a problem?

Wait. No one spend another second thinking about this please.

You'll all laugh, this is a good one. The EPROM that's in there now is erased. I bought a pair of T2s, this one had revision 8 and the other revision 2. Since I was shopping and modding the other one, I took the v8 chip out and installed in the other.

Then I UV erased the v2 chip but couldn't burn the v8 image because my software didn't have that chip in the database to recognize it.

So I have a blank fucking chip in there right now because I forgot I erased it. Looking for another chip to burn the ERPOM and will report back. Someone is coming to look at the working T2 in a few hours, so I ain't pulling the chip or doing anything at all to that T2 due to Murphy's Law.

Fucking A, what a dope I am.
