Question about Sony SDM-HS75 17" LCD Monitor

1 Answer


I have a problem with the backlight of this monitor.
The monitor is black.
He recognizes the input of the PC and turns on the 5 V signal on pin 7 of the High voltage inverter, but no light.
The power supply is ok and delivers his voltage to the inverter.
Are there any schematics somewhere?
Many thanks for your help.
PS could not find the correct model in the list, but the monitir is a SDM S81R silver

    Great people on this site.
    Thanks Zwarrior.
    Ideed the FT Fuse beside the R1 resistor was blown.
    Was just the blimp to find out what kind of fuse.
    The panel consumes 1 Amp with no input, just showing the typical "check connection" message.
    With normal picture it's 2.6 Amps reading on the lab.power supply.
    I'll put a 3 amp one in place.
    Thanks again and a nice day to all the community.

    Sir i did my homework on internet n i found this:::

    I believe there is a company called LCDPART.COM has lists many
    types of inverter boards.
    If you are good with electronics, I would suggest that you check the
    inverter board before buying a new one. I have had 3 or 4 where
    just the SMD fuse was blown. Often the SMD driver transistors that drive the transformers at the ends of the board are shorted, causing the fuse to blow.
    Hope this helps....

No input signal, go to power save sony sdm-hs93

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.

You open the inverter unit and check any dry soldering is there. Some times dry joints inside the inverter unit cause this type of problems.

LCD Monitor Goes Black during Use

I had the problem sometimes, but then I connected a second computer to the analog input and found out, that the screen didnt turn black but switches between the inputs on an on.

I found out that the "input" button seems to be short or damaged, as the behaviour was invertable by pressing the button. I blew into the button some times (a very naive solution, yeah) but it worked, the switching stoppped.

Sony SDM-HS74P/S 17 - Monitor won't stay on the right picture

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.
