Man do I need some serious help. A friend of mine whos dad passed away sold me all his darkroom equiptment. Everything was boxed up but it looked good. But now I am very upset as some of the items seem to be broken

I turned the timer on but all that happened was the hold light was on and I saw an F and now the screen is blank. I tried to use the keypad but nothing...

Any ideas?

Then I opened another box and pulled out this cold light head but it was busted and I have no idea what the stablizer is for. How can I fix this head?

So at this point I was totally bummed then I found another box and pulled out a VC head! ANd then things I thought were cool. I attached the cord to the VC controller and plugged in the enlarger and the controler. I flipped the switch from print to focus and this weird purple / blue light came on. So fine. Then I tried to adjust the light with the center dial and nothing, the light stayed constant and did not dim and the direction said it should dim. Any ideas???

If you could help me I woudl greatly appreciate it. I just want to print! HELP! What do I need to do....

Thanks everyone in advance,
