Picture on my monitor too dark.LOPT Screen adjustment not present?
 

Recently my monitor picture became dark. I have the setting on the
monitor on the highest, brightness and contrast setting level.


2 Focuses adjustments on the LOPT are present and were glued and they
can be moved up and down.

But Screen knob on the LOPT is moulded into the casing and is
unmovable.


I was wondering if there is another way to increase the brightness to
the tube other then the screen adjustment.

Monitor Model No.IPEX v798

thank you for your help.

The screen adjustment usually has one or more fixed resistors, in
addition
to the adjustment. One of those is likely to be bad (they're usually
in
the 220k ohm range, located near the CRT socket). Take the usual
precautions, and compare the measured resistance with the
color code.

One of the 'focus' adjustments is likely to change the screen (but
they're mislabeled - no surprise there, the 'screen' label was also
wrong).
