Lcd blank


From the information I have, the unit will need to be repaired. No quick fix to repair for a blank display problem. Either the cable to the LCD screen became detached or the display is bad. The cable will be internal.

Slow coming on. Blank screen until you press the on button a few times


guest, If you do not have any time to explore (investigate, read) then trade your old unit for new!! If that not option you wish to take , then read fixya monitor profiles of "louie12fix" , "budmrtn", "buddymc" and other tech's that specialize in repair of "cold-cathode-fluorescent-lamp back-lit lcd monitors. Follow all "links" you find in the profiles and view some video clips on YOUTUBE that deal with "lcd monitor disassembly" and "lcd monitor repair" to learn just WHY your unit acts the way it does. Why don't you try the "flashlight-test" that EVERY owner of an lcd monitor should know when a BLACK or BLANK screen shows up when it shouldn't be there in the first place. My best guess is that your monitor's problem is internal to unit and not a software problem. 12fixlouie Bye for now

Va912b first cuts on with mostly blank but with broken strips of lines from top to bottom and have some together and some with blank seperation between them. then goes blank


joaye, First place to look would be the monitor's "switch-mode-power-supply" and /or the INVERTER circuit. When strange things start to occur with LCD monitor's w/CCFL backlighting, the first place to look would be the internal or external SMPS for the unit. You should be careful in your third use of the word "BLANK". Some monitors will be BLACK and not BLANK! Some will be both BLACK and BLANK. Read more Black screen stuff in my profile and you will understand WHY your unit is behaving like it is and some useful options you and other's like you have. Also visit www.ccl-la.com/badcaps.htm and www.lcdparts.com or YOUTUBE for videos on lcd repair or lcd monitor disassembly FYI DIY type stuff. I'm 12fixlouie on fixya.

Blank screen


probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver IC thus you could only see white display. A replacement of LCD panel is the best solution. I suggest to bring the unit to an authorized service center to properly diagnose & fix the problem. regards
