Hello. My girlfriend bought this Mac from a local technical college resale shop. We used it for a month then she bought a newer, bigger model. She traded this model to my repair shop for a iBook G4. We had it in my shop for a month, worked fine. One day we got a gray screen and it made a really weird continuous beep sound. I shut it down, took it into my shop repair station and took it apart. I took the back panel off, plugged in power cord, mouse and keyboard. I used a screwdriver to connect the power switch contacts. The front light turns on, no fans, no chime. LED's 1 and 2 light up, but not 3. Does this mean the video chip is bad? Or could it be the LCD or Inverter? Thanks in advance for help.
