SONY HS959 MONITOR DOES NOT OPEN UP

screen resolution set to high start in safe mode select 800 x 600 at 60 hz save and restart if vga cable is detachable replace cable and check for bent pins

Hello,
I believe the max resolution this LCD can support is 1440 x 900 / 75 Hz. If you set your display resolution higher then that, you will receive the input signal out of range error. Your LDC turns off to protect it self from the invalid settings. If you can not change it back once your PC boots to windows, you may have to do it in save mode by pressing F8 once you power on your PC and before the windows loading screen starts.

power save mode indicates no input signal. Check the input signal with a known good monitor. if the signal is good then dell monitor is faulty. Power cycle (unplug the power then plug it back in) the monitor to reset to factory and if it still goes directly into power save mode the unit is faulty.

I f you see the message on the screen indicating 'NO INPUR SIGNAL', you need to check the VGA cable and both ends of the connectors also. Try this monitor with other PC also.

This SDM-HS73/93 have common problem: bad backlight assemblies due to poor workmanship in sodlering works, see my pictures below. You should also inspect the caps. This is not recommend for DIY.

looks like there is problem with ur signal cable check that monitor signal cable is tightly fixed or contact ur product support center.

cb5547, Do you SEE the strange "no signal""no input" messages when other programs are running such as MSword, Excel, IE8, ? I would guess that when very strange things begin to occur "ON SCREEN" of an LCD display, that something might be about to go bad in the unit's power supply. In any case a technician should evaluate it for you. In the mean time hook_up (swap-in) a working monitor to prove that your PC is working correctly. report back here with a new comment on fixya and I will suggest a few things you can try.

might be something wrong with your monitor's data cable

Check video card in the computer by buying a new video card or used one your choice, if this does not shore it up the its the motherboard itself.

Thanks
