My Sony SDM-HS93 has a VERY intermittent display. It only displays for about a half a second and then blanks for a random time. Any ideas?

Common failure in the SDM-HS73/93 is the bad lamps assembly due to poor soldering works.

Hi..my sony model sdm-hs93 lcd monitor flutters for a couple of seconds right before the screen blanks out. But, if I leave the monitor on for a day in sleep mode, the next day i can hook it up to the...

Hello,

I think the problem with your monitor is that, the picture board on the monitor is malfunctioning that is why it keeps going blank after a minute.

What you need to do is to replace the picture board on your LCD monitor, replacing the picture board will solve the problem, because the picture board on the monitor at the moment is bad and will need to be replace.

Replace the picture board and you will see that the problem will not repeat itself again.

Take care.

Sony SDM HS73 ''turns off''

One thing I know for sure on this model HS73/HS93 is that the backlight assemblies failed due to poor soldering works. This may the problem with your monitor.

It is very time consuming repair works that I doubt very much if repair shop will do the work.

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.

Sony hs93 screen doesn't come on unless I hit the power button a couple times, then, sometimes display is wrong dimensions , so I hit power button again, straightens up. also, sometimes it comes on with...

First, check for properly connected cables. Disconnect and then re-connect to ensure quality signal path. Use a known-good cable to test. If no joy, turn off computer and remove video card, then re-install it. Sometimes, after long periods, the contacts on the card can become oxidized and have intermittent contact. This will also give you the chance to check for large amounts of dust settling on the components--dust, combined with humidity in the air, can play havoc on computer cards. If still no joy, then the processor board in the monitor might well be defective. Power, signal/resolution decoding is all handled by IC chips. I like to start simple and move to more complicated(i.e. expensive) problems.How old is the monitor? If under warranty, replace it. If not, a repair facility or replacement is your next move.---Rick

Screen turns on for a second then turns off

Your power supply is blown. If you have some repair knowledge then pull it apart and look for caps that have raised or bubbled tops. They need replacing I do this repair all the time. If you don't want the monitor please let me know I will pay for shipping. I repair them for the school.
God luck.

Sony SDM-HS53 Monitor Goes Blank

I used to have the same problem until I discovered that the cables in the back of the monitor weren't securely connected. I have a very similar model monitor to the one being displayed here
