20 Most Recent Sony SDM-HS73P 17" LCD Monitor Questions & Answers

Get monitor out of burn in mode by unplugging the power to monitor then while holding down the power button on monitor plugged in the power cord to the monitor all while it is connected to a running computer. Turn the monitor off with the power button. When press the power again the burn in mode should be gone and the monitor should display the computer

Possibly the backlights have failed. The screen part may be working normally. Get a bright light close to the front of the screen, see correct image faintly. Commonly it is failure of the high voltage inverter circuits that power the backlight fluorescent lamps. You can probably buy replacement circuit or repair the one you have. I have done this on another model. You need to search the web for experience of the same model. RDL.

my computor monitor keeps turning a very bright green, When it does I cannot see anything thing clearly, yellow and reds look the same. how do I fix it.? Please help Thank you

have you tried different outlets?

One possible cause of the this problem is the bad lamp assemblies due to poor soldering works, please see the pictures here: http://s807.photobucket.com/albums/yy352/budm/Sony%20SDM-HS73/
The repair person should also look for bad caps in the power supply section.
You will need test lamps to test and verify if the lamps assemblies are good or not.

You need to also check the caps in the power supply, etc.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

This is not an inverter problem. The inverter only powers the fluorescent lamps in the back of the LCD panel.

It is probably a fault in the LCD data decoder circuit or a failing connector between the decoder circuit board and the glass LCD panel. If you took it in to a shop, they would probably charge you a full hour's labor minimum - compare that with the price of a new LCD monitor.

It appears you may have a bad backlight. If you can see the picture content with a strong light shining at an angle to the screen while it is dark, then it is definitely the backlight. Most sets shut down shortly after getting a failure signal from the backlight inverter although you do not mention that happening.

The backlight uses two or more Cold Cathode Fluorescent Lamp (CCFL) tubes, and they'll have the same flickering as a failing standard fluorescent tube. If the light has a pinkish cast to it, this is a common sign that one or both of the tubes is bad. You may see the flashing on the top or the bottom and the other half of the screen will be dark; this means one tube is dead and the other is dying.

Take it in for repair seems to me that you have done all that you could to fix this monitor it is a flat maybe worth the repair if the repair is slightly less or more I would consider spending the green on a new one they are getting down in price. Thanks for using FixYa! John

Common problem with is SONY 17" and the 19" are due to fail lamp assembly as shown in my pictures here which will be the worst case. You will need to check the other parts in the set first.

Try to see if your signal cable from the systems unit is connected to the LCD. If it is connected, then that means that your VGA is not sending any signal, try connecting your LCD to another system unit and see if it works.

It may have bad lamp assembly as shown in my pictures here:

Also check the DC filter caps.
If you are going to DIY and have proper tools and know safety precaution then please read on: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also.

no estoy seguro pero creo que el problema esta en el circuito integrado GM2121 que esta precisamente en la placa que mencionas...ya que a pocos minutos de estar encendido recalienta mas de lo normal...

May I ask exactly what it is not doing? Flashes on then goes off?

This monitor has known problem with the CCFL assmblies.
Best to get new switch board assmbly if that is the case, I never run into one with broken switch yet in thsi model.
You can get this tactile switch from www.mouser.com or www.digikey.com just have to match the foot print and height.
