latest iMac mod won't start.. No lights. Took the 'working' machine to local macheads shop. They discharged the CRT. I took it apart, put the headless iMac back together and won't start. I double-checked all my connections. I'm still using the Apple power supply. Should I have removed the logic board before having the CRT discharged??

only wires not connected:

main black line to the CRT (suction cup) and the 2 red wires that also went to the CRT.
