Question about Dell UltraSharp 1800FP 18.1" LCD Flat Panel Monitor
I've been running two computers off of the 1800FP for some time (one on the analog side, the other using the DVI input - I toggle between the two with the front panel switch). Suddenly, the analog side stopped working. I've tried:
1) a brand new VGA cable
2) hooking up a different computer
There is a very faint glow on a black screen when I activate the analog side. The computer hooked up to analog can detect the presence of the monitor, and system preferences can be selected, but the display remains black. The DVI side works just fine.
Sounds like the video controller board inside the monitor has blown a transistor. They are only about 3mm wide so not easy to spot even if you look closely.
It's a fairly rare fault, though not unknown to happen without reason.

a short HDMI cable. You should not encounter
difficulty if you use an HDMI cable shorter than 16.4
HDMI cable transfers both video and audio.
Separate analog audio cables are not required (see
illustration below). Some CDVs (video CDs) may
not output digital audio signals. In that case, you
may hear sound by connecting analog audio cables.
However, if you connect analog audio cables with
this connection, the HDMI terminal on the TV will
not receive the HDMI digital audio signal and you
will hear analog audio only.
To ensure that the HDMI or DVI device is reset
properly, it is recommended that you follow
• When turning on your electronic components,
turn on the TV first, and then the HDMI or
• When turning off your electronic components,
turn off the HDMI or DVI device first, and
then the TV.
To connect a DVI device, you will need:
• one HDMI-to-DVI adapter cable
(HDMI type A connector)
For proper operation, the length of an HDMI-to-
DVI adapter cable should not exceed 9.8 ft (3m).
The recommended length is 6.6 ft (2m).
• one pair of standard analog audio cables
