What watch is this?Never have seen this watch
Antwoord op "MacBook inverter board...how to test?"What I did was take a lamp from another broken laptop I had and used it as a tester to see if the inverter was okay. That did it for me - you can not test the inverter output with a digital meter.
Antwoord op "MacBook inverter board...how to test?"Saw this on another site - the pinouts match my A1211 Macbook Pro inverter feed plus. http://www.techsupportforum.com/forums/f...-lcd-backlight-on-mac-powerbook-g4-aluminum-17-a-483015.html Re: Dead LCD Backlight on Mac Powerbook G4 Aluminum 17" This problem is solved... sort of. The bottom line was that the logic board was NOT outputting any voltage for the "dim control" input to the Inverter board. According to some other info found on the Internet, the "dim control" pin should have a voltage ranging from 0 to +4 volts depending on the dimming desired (where 0V = no light, 4V = max light). Since the logic board wasn't outputting any voltage on that pin, the backlight remained off. So, since I had no intention of buying a new logic board for such an old computer, I decided to just manually put +4V on the pin. Here's how I did it... First off, the CORRECT pin names and voltages to the input connector of the Inverter board are here (again, this is for Powerbook G4 17" Aluminum). This is slightly different...
