NEC LCD HELP

[[email protected]]

I am repairing a la-1831jmw-bk rev a2. Everything hardware wise tests out
fine. It briefly comes on, you can see what the computer is trying to
display for
about 5 or 10 seconds, then it says it cannot detect what is being displayed
(NO SIGNAL) and it clicks off. You can turn in on again, and it does the
same thing.

Any Ideas?

Thanks!

I see a lot of crt monitors with this problem too. Unfortunately I
don't know what causes it; I'm not a monitor expert. But I have noticed
that most monitors using a sony controller/osd chip need that chip
replaced at some point.

Computer is set to a non-supported resolution. The display will
display the boot up information but as soon as the computer changes to
the non-supported resolution the lcd turns off.

The cable between the monitor and computer is bad.

There is little you can do to fix the inside of the lcd monitor for a
problem like this as the signal process board is multi-layer ultra high
density and no service information is available.

If it is a non-supported resolution issue, and if you are using
Windows, then boot your machine in safe mode. R-click on the desktop
and set the display properties to a safe resolution such as 640 x 480
and 16 or 256 colours. Then reboot your machine in normal mode and use
the same procedure to progressively select a more appropriate
resolution and refresh rate.
