Question about Sony GDM-400PS 19" CRT Monitor

Open Question

Monitor wont turn on

Sony multiscan 400ps went black while working in application. When computer boots monitor is not responding, amber light blinks every 2 seconds. I bought this computer used in 1999, it was manufactured in 1998 and was refurbished at the time I bought it. I determined the computer hardware is fine as a stand in monitor works in it's place. Can someone tell me if there's anything I can try to get it working? I have very limited electonics training. There have been times when unplugging/plugging this monitor in has enabled it to be turned on. This didn't work this time, however. I also noticed that the power switch seems to be sticking at times. Thanks, Tim

When the screen turns black again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself. Let us know what you find out and please don?t forget to rate this posting.

ok.. most probably the data cable of your monitor is damaged.. try to check it if the pins are still in tact.. if not, then you should replace it with new one..

SOURCE: Sony SDM-HS73 Not Staying On

The problem is with power inverter, usually the capacitors go bad and need to changed, they might be bulged and or leaking. Very cheap fix, less than a buck apiece and an hour with a solder iron. Google it to find more info.

Monitor is black. How do I fix it?

if the monitor led indicator is amber and and the hard drive (usually red) indicator on computer is blinking red. that means your computer is working but onboard video is dead. if under warranty, bring it back for replacement or repair.

Monitor stuck on black, menu buttons not responding

It's sort of a solution, but I work in a computer shop and got this screen in yesterday. I looked at it closely and it's actually the backlight that died. I pulled it apart and found that three of the 820uF/20V capacitors had swollen up. If you replace them then you should be fine, but I went for a different approach and took the inverter board from a laptop and put the in the screen and used an external power supply. It's a bit dark but it works fine now.
