Data collector LCD screen problem

[johnWM_52]

Hi
(This is submitted under graphics card but that is only because it forced me to select a subsection)
I have an old data collector with a small monochrome LCD screen.

About three months ago I noticed a small blue patch, (see attached images) which is steadily growing in size.

It is not associated with the pixels as far as I can tell and remains visible even when the screen is not in use.

Its size has doubled over the last month even though the data collector has been switched off.

It is an old data collector that I have used for over 15 years. It cant be replaced and serves a valuable purpose.

Kind regards
John McBride

Looks like those are dead pixels on your LCD screen.

Is it floating over the images on the top glass/pastic? I've seen some funky issues with LCD panels but don't think have come across this before. The LCD can burst but your images don't look like that is what is happening.

Almost looks like a blue mold or something. Or someone with a blue pen likes to color.

Something about blue spots happening with older Sony TVs but there are no pictures to compare to. http://www.hometheaterforum.com/t/257526/new-guy-to-this-site-need-help-with-blue-spots-on-lcd-rear-proj-sony-screen
