My PC monitor (17 inch glass tube) is about 4 years old and has
been used heavily. I took the cover off to fix a loose
connection because the picture was sometimes jumping.

Inside the circuit board was quite dusty and rather sooty. The
CRT tube and anything neary was very sooty.

Is there any merit in cleaning (hoovering or gently
wiping) this dirt?


Thank you all for your advice.

All this now makes me think that my TV (which uses a 19 inch glass
tube) would also show an improved oicture if it too had the dust
cleaned out of it.

Is this correct? Or does a TV differ in some way from a PC monitor
when it comes to getting visible improvements from dusting?
