Navegando por alli encontre como posiblemente solucionar un problema de pantalla en una compac Armada y es que el problema es que la pantalla se queda en Blanco y se necesita apagar y volver a encender para que deje de dar el problema.
Pero encontre la siguiente explicación y espero les sea de ayuda a todos ustedes.


I have a solution that will fix the problem for 6 months to a year for most of you but you will then have to repeat. The problem is that Compaq went cheap when they built this machine and they used silver for the connector pins instead of gold. If you know anything about silver you will know that over time silver becomes oxidized. This is why after reseating the connection for the display plug will solve the problem for a short time. To fix you need to unplug the power and remove the battery from the system. Make sure there is no power going through the system or you could fry your system board. Now remove the cover on the left that covers the two connectors for the display. The black small one is the power and the white one is the output from the video card to the display. Go out and purchase some silver cleaner and a small paint brush (like what you would use to pain model cars) this should be small enough to do the job and you should not be able to bend any pins. Do not use a q-tip or anything of that nature, you may bend the pins and if you break one you are screwed. Simply dip the brush in the cleaner and run it back and forth over the pins. Don’t have a whole lot of cleaner on the brush you don’t want to get it too wet. Now re-seat the white connector and take it back off, repeat this a few times to work the cleaner up and down the pins. Remove the connector, let everything dry over night and then reconnect the connector and put everything back the way it was. I have done this on two armada 1750s and it fixed them both for about 6 months and then I had to repeat to get another 6 months. There really isn’t a permanent fix other then using an external monitor.
