sammichSID strange screen behavior, ideas?

[Cutter]

Hey all! I just finished my sammichSID kit. It passed all the voltage checks, so I put the IC's in and powered it up. The screen only turns a very light shade of green, and doesn't change with either of the trim pots. Strangest thing I noticed, is the female ac port on the main board seems to be faulty. If I jiggle the male end of the AC adaptor, the screen lights up a bit, and then goes dark, unless I hold the adaptor at the correct angle. I tried de-soldering and re-soldering the connector, but I still have the same issue. I did manage to get the firmware loaded successfully via MIOS. My next troubleshooting step is to try swapping my monitor board with my friends working sammichSID, and see if I get the same result. Any help is much appreciated!

Whats your psu specs? And if the female connector is bad - it shouldn't be - it might be wilba's domain to help u out with a new one...

Also, measure the voltages with it stuffed with ICs might give u a hint if something is wrong somewhere. If psu current specs are too low, regulation may suffer, and u get bad voltage values...

I should really get myself a sammich, because I know nothing about its circuitry other than what I know in general about mbhp circuits.

What about the LCD, does it get the right voltage... There is different voltages to be put to use with different LCDs, but if u got it with the kit, I'm sure u have that under control.

Sorry, can't help u with more specific info than this.

Nils? Wilba? Hehe, one only need to cry out...

The power supply is the recommended jameco, and it powers my buddies sammichSID without problems. Checking the volts with the ICs in is a good idea!
