Helppppppppppppppp!
My screen turned all red..
and I can't fix it..
I mean everything is red.
I can't read any red fonts, and it's all red!!! helpppppppppp.
I already try doing a system restore.
It's got to be in my computer, because if I unplug the monitor from the computer, a red, blue, and green bar are there...

Unplug the power from your monitor
unplug the cable from the computer
Plug the power back in.
Plug the cable from the computer into a different computer
Does it work?

Tried all but the plugging into another computer.
Only because, when it's not plugged into my computer, a box, like a screensaver, floats around with normal colors.

ALSO REMEMBER THE CAPACITORS CAN HOLD LARGE ELECTRICAL CHARGES EVEN WHEN UNPLUGGED FOR LONG PERIODS ESPECIALLY THE ANODE ON THE END OF THE VACUUM TUBE,
so get someone who knows what they are doing and knows how to discharge the caps and anode for you

yeah checking it on another pc is the best thing to try,
another thing it could possibley be if its a CRT and not LCD/TFD is this I found,
oh but before you try this CHECK ALL THE CONNECTIONS in case its just a loose or faulty cable and again try the monitor on another pc
| Code: | Description
This article is from the Apple II Csa2 FAQ, by Jeff Hurlburt with numerous contributions by others.
16.008 Suddenly my monitor has an all-blue (all-red, etc.) screen! How do I fix this?
You probably have a blown choke on the little chroma board mounted to the
back of the CRT. The choke will be connected to one of the larger, R/G/B output
transistors. Use an Ohmmeter to find the open choke. Replace the bad choke with
'one like it' or brew your own: wind about 25-30 turns of #30 wire on a small
ferrite core.
A more detailed procedure is presented below ....
1. The part that causes the problem when it fails is a "choke" or "inductor" ,
it is mounted on a small circuit board attached to the back of the monitor tube
itself. This part looks like a small blue ceramic ball with two leads coming
out the bottom, and is color coded for 10 microhenries.
2. There are three of these items on that circuit board, and if any
one of them fails, the symptom is a screen all of one color, with
total loss of any controls of the monitor. The parts are identified by
number, and what color the screen is will tell you which one to
replace.
L6R2 for a Red screen
L6G2 for a Green screen
L6B2 for a Blue screen
3. You can probably get a 10 microhenry choke at Radio Shack, or it is
available for $1.28 (plus a $5 Handling charge) from Digikey Corporation at
(800) 344-4539. They take Mastercard, Visa, and C.O.D.. The Digikey part
number is M8025-ND.
4. After replacing this part, the monitor colors may need to be readjusted via
the small color trimpots on the same circuit board. |

Well, thanks..
But it just randomly went back to normal.
And it's an LCD, but thanks anyways.

sounds like a loose connection then,
at worst if it happens again maybe try out a new cable and see if that fixes it,
anyway glad you got it sorted out,
gladder you havent got to mess around this 50,000 volt anodes with your LCD lol

Yeah it was most likely the cable, since it isn't the monitor itself. (It performed that self check)
