In that case or symptom,the problem is either come from the power supply or back lights inverter board.The screen or the display is totaly black when the back lights is not working. The inverter board have blown surface mounted fuses that my cause of shorted transistor,transistor or leak capacitor.Thanks.hope it will help you..

My mobile was falldown. then i switch on my mobile. but display is fully black but cal & msg coming


hi there!

the lcd screen must have been damaged due to the fall. try powercycling the phone (turn off, remove battery, simcard, memory card) leave it like that for 2mins, put everything back in. if the same problem happens, try pressing the sides of the lcd screen, if the screen doesnt respond or theres no change, you have to bring it to the repair shop. they will replace lcd screen.

My sdm-hs73 moniter the power is on but screen is blank, what could be wrong


First check brightness and contrast settings.
If all good could either be your lcd back light has gone or the inverter. To check if its the black light shine a torch through the back of the screen to see if you can see a slight image on it, if you cant see anything the inverter board is faulty and to repair needs to be changed.

Blank screen and flashing green light near on/off switch


fred_lane, Well, it could also be just black, or both black and blank! DID you do flashlight test that every CCFL back-lit lcd monitor owner should know how to perform and interpret the results for when confronted with a black screen problem that is not caused by sleep mode?? I can only suspect a bad "switch-mode-power-supply" that is in partial or full SHUTDOWN mode due to it detecting a FAULT CONDITION with itself or the CCFL inverter circuit supply. Read other options you have open to you in my fixya profile! 12fixlouie Hope this steers you in good direction.

Monitor only stays on for 3 seconds


There is probably a bad capacitor within the monitor that will not allow the picture to "hold" in the on configuration. This will need to be replaced. You can send it back to Phillips, or 17" monitors are pretty cheap these days. I would suggest a Samsung or BenQ. They both carry 3yr warranties.
