The image on my hp 1955 monitor ok on start up by swiftly degrades with small thin rectangles (about 12mm long by 2mm high) of single colours mostly red but some blue and green. Qite qickly screen covered and quite unuseable. This started a few days ago in a small way but has increased over the days. What is happening? Can it be sorted? Thanks, James.

Standard VGA (with DDC VESA) pins are H-Sync = 13 and V-Sync = 14. R G B are 1, 2, and 3 respectively. Ground is 5, Red Shield 6, Green Shield 7, Blue Shield 8, 5V 9 (if there is a pin in the connector), Sync Return 10. 4, 11, 12 are ID Bits 2, 0 and 1 respectively, 15 ID Bit 3 (or clock pulse). If your connector does not have anything in 9 and 15, then it is not have DDC VESA.

Hello, there is a problem with your monitors picture tube. May be it might have been damaged as a result of over power or even because of over use. Just try to change the picture tube or change your Monitor.

More likely to be bad LCD panel due to failed TFT (Thin Film Transistor) driving circuits, new panel will be needed.

check your VGA card is it there in slot correctly? try to connect it with another working CPU. and tell me what happens

this is real old right
no photo off i messing up, how can we guess, what you see?
amazing....
my guess power pack shot.
i guess you cant barrow a monitor and try that?
2nd guess blind, the back light failing
or is damage if it was hit, the LCD will have damage
gently flex the frame goes nuts, bingo.

try plugging into an external monitor.. if the screen looks ok then it is most likely the laptop LCD screen is bad.. had the same thing on a HP laptop .. replaced the screen and all was well again with the world...

Hi Bruce,
Sounds like you have shorted or open Vertical Filter Capacitors. ( you may also have a bad vertical drive chip now since you've waited to replace the capacitors). You'll need to replace the bad capacitor/s and if the problem doesn't go away, replace the chip also. And as always, check for any cold solder joints ( bad lead connections to the printed circuit board ) as you replace the bad components.
I Hope this has helped.
