New chassis and my Die Hard monitor still has no blue

I just got my new chassis in the mail from alva amusments and my 25inch die hard monitor still doesnt have any blue, whats next?
 
If you have an old school TV repair center in your town, give them a call to see if they have a rejuvenator. Most of the time they'll check/test/rejuve it for you for next to nothing... even if they do charge a bit for it (I wouldn't pay more than $20), it's still cheaper than getting another monitor/tube.

FWIW, I had a... I think it was 4600 in my Pole Position and the tube had a bad red gun. Hooked it up to the rejuve, ran a few "clear shorts" and "clean and balance" and she was good as new.

If you want to do a quick and dirty test of the tube, you can short the gun in question (blue in your case) very briefly. That's what I did to mine before I borrowed the rejuvenator from work. Shorted green, screen turned green. Shorted blue, screen turned blue. Shorted red... nothing. YMMV and do it at your own risk.
 
blue

First of all, check and make sure your blue gun pin on the tube is not bent up so it is not going into the socket before you do anything else.
 
tube

more likely then you have a bad blue gun and even rejuveing it wont help it , if two different chassis did not help. of course maybe you dont have a blue signal going into your chassis.
Put your meter on the plug ground wire and blue wire on your chassis and see if you get a voltage or two and it flukuates up and down. compare it to red and green also. if you get nothing there then either its your wiring or your board.

the signal is fine, i hooked up a 19inch g07 and it was fine
 
Well then, the tube is the culprit and the only chance is to rejuve it but odds are when you have not blue it will not come back or at least respectable.
Take the monitor to a repair shop and give them $10 to rejuve it. It does not take that long.
It looks like your going to have to change out the tube. Danny downer I know.
Good luck!
 
I have a STV die hard cab with a U2000 doing the same thing except on red. I've done all the same steps listed here in my attempts to fix it too. The U series is crap IMO. It's too bad, the pic is sharp and crisp, no burn in either. Bullocks!
