You simply grip each side of the monitor low down on each side of the coloured strip that wraps around just behind the front. Ensure your finger nails are engaged under it, then pull hard. This will pull away the wrap around strip exposing more screws, its only clipped to the case. Unless you are a repair tech it won't do you any good, as even if you then removed the metal screening and base plate you would not be able to detect any fault just by looking. In my work I've opened up around 40 of these now, both Graphite and B&W. All but one had either defective flyback transformers or flyback induced faults making the monitor unrepairable. These monitors were made by LG for Apple and have only one weak spot that makes them very unreliable, the flyback transformer. It can cause these faults: Loud snap/arcing noise, image fades, comes back dark, enlarged and out of focus, corrects itself over a few seconds. This can happen once every few months or almost immediately its turned on. As above, then monitor fails to power on. Arcing damages internal circuitry. Once this arcing also zapped a G4 video card. Flyback transformer fails shorting B+ supply to it. B+ regulator normally supplies around 180V to flyback, drops to a few volts. Power LED on, no display. I've only changed 5 flybacks in these for maintenance contract customers, most users don't want to pay and buy new. I'm in the UK, and the flyback cost was around 90 gbp ex VAT (EU sales tax, source was a supplier in Netherlands). Note, in this monitor amongst other things, the flyback generates around 26 KV for the CRT, an area not to me messed with unless you know what you are doing. Even in a dead state, there is a possibility of 320 VDC present due to charged capacitors. Steve Bell -- G-List is sponsored by <http://lowendmac.com/> and...
