There is a problem with Apple Multiple Scan 20 monitor:
on a totally random basis the display switches from true colour
to a colour where everything looks slightly blue in tone.
Can you tell me what is the cause of that problem? Would I be able to
repair it myself?
I fixed in the past my old monitor with help of people from internet (then
I only had to exchange a capacitor to make it work normally again).
Perhaps in this case it is similarly easy to fix the failure?

I hope you can help.

Thank you.
