My iMac (1999 DV SE) has been having some issues driving the CRT. sometimes it has a severe screen tear when idle and after running for a while the CRT refuses to wake from sleep, although I can hear it trying. Sometimes when turning it on, only the Green light (No HDD, no Fan) on the power button turns on and I can hear high-voltage kick-in just for a split second. Are these just symptoms of an Analog Board in need of a Recap? Any help is appreciated!
