for the purpose of expunging the screen rot. Need to get behind the screen thingee there
First extend the little leg as far as it will go (put the monitor the
right way up and press the button on the side, them lift the back edge).
With the leg extended. put the monitor face-down. On the back there's a
circular plastic cap. Prise (Pry?) this off wit ha screwdriver and undo
the screw thus exposed. Then lift off the cassing.
From what I remember, and it's been years since
I've been inside one,
theres a single PCB on the top (component-side down) and
the CRT. I think
you have to discharge and disconnect the anode connector from the CRT and
remvoe the CRT base connector. I can't remember how the yoke is conencted
ot the PCB, it's it's plugged in, it's easy, if it's hardwired, I'd
desolder the wires rather than removign the yoke from the CRT at this
stage.
Then remvoe the PCB screws and the PCB, I think 4 more screws retain the
chassins metalwork and the CRT, it then all comes apart.
Be careful if you are tryign to cure screen rot. I am sure the second
faceplate layre in this monitor is part of the implosion protection
ssytem, and the idea of removing it and leaving it out, or not proeprly
bonding it to the CRT envelope would seem to produce a dangerous monitor.
