Sony sdm-x73 tft

TRY WITH A OTHER MONITOR ARE THAT OKEY YOUR MONITOR ARE PROBERLY BROOKEN.
ARE THE OTHER MONITOR ALSO BLACK YOUR VIDEOCARD ARE PROBERLY BROOKEN.
ALL CABELS SHOULD ALLWAYS BE SEATED TIGHT.

You might try checking you monitor setup, you should be able to shut it off by unckng the proper box

The information window/box will come up if the menu button is pressed and held down.. verify that the menu button is not stucked.

The setup cd for the monitors are no longer available since the manufacture date of these units are way way back ago. you can get the drivers and software for you monitor from the link below
esupport.sony.com

Here is one thing you can do to help get to the root of your problem.

Take a flashlight and shine it on the screen once it has gone to black. If you are able to see the screen information (your desktop) then you have a back light problem.

The fact that the bulbs come on at first and then go dark tells me that it is probably not the bulbs themselves and the fact that your power led stays on tells me that it is probably not the power supply either.

The most likely cause is the power inverter board which is usually a separate board attached to the video mother board and it powers the back light bulbs.

This is not an easy fix for someone who is not familiar with LCD displays but it can be done. I did a Google search on Sony SDM-X73 (if that is your monitor) and could not find any stand out instances of complaints. I also did a eBay search and could not find anyone selling replacement boards either.

Truthfully, my solution for you would be to replace the monitor. It will probably cost you more to have someone work on the monitor and fix it than it is worth. You can find 17 inch flat panels on eBay or CraigsList for cheap these days and I just saw a brand new Acer 22" with a 3 year warranty on CompUsa.com the other day for $150.00.

You can try taking it apart if you want to but recycling it is the better option.

Good Luck,

John

Try this:

Under the menu options, there's Menu Lock. Switch it to "On". It worked for me.
My menu button wasn't working, so to access the menu, I had to hold down the arrow up button and push the arrow down button till I got to the Menu Lock Option.

The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for ten seconds.

• If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
• If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD.

I HAVE ONE SONY MONITOR MODEL SDM HS75.

I WANT THE SYSTEM CABLE OR IT NUMBER EXIST PLEASE

first, 68.5 khz -85hz means horizontal raster frequency of source signal is at 68.5 kilohertz and repeats vertically at 85 hertz. (hertz means "cycles per second). the sony monitor cannot "read" the signal being sent from the pc. change the screen resolution to a lower number like 75 or 70 hertz vertical.
