Samsung lcd le27s7 screening problem


Hello,

The problem with your lcd monitor is that the picture board of your lcd monitor is faulty that is why it power on for one second goes gray and finally black with only sound.

Since the power led button is on and it still give sound but no display, it means the picture board of your monitor is bad.

All you need to do is to take the lcd monitor to any local repairer or any service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix all alone in other to complicate issue.

Take care

Hannspree HF-289H LCD Monitor not displaying anything.


conor455, I am sorry to hear that your lc display has been struck down with the "BLACK screen of DEATH". Most likely the "switch-mode-power-supply/inverter supply" has failed!!! If your monitor is out of warranty then i suggest that you find your way to my fixya profile and read some of the responses I and others have already written about the BLACK screen symptom and what you can do to try and repair it!! YOUR DISPLAY IS SICK. The SMPS is in SHUTDOWN mode trying to save itself from further damage and or catastrophic nonrecoverable failure. eg. sparks, smoke, fire!! Leave your monitor OFF and do a little bit of research of BAD electrolytic filter capacitors and other stuff that causes LCD backlight's to fail to light-up. Conor, when you asked "ANYONE KNOW THE PROBLEM?" all I can say is visit YOUTUBE and search for and view some of the longer vid clips of "lcd monitor disassembly and/or lcd monitor repair to help YOU to make a decision as to the fate of your HF-289H. Bye for now. If this info has been of some use, please rate this response on fixya! 12fixlouie aka louie12fix

HP w22 Monitor display disappears after about 2


bill, if monitor not covered by warranty, the check out YOUTUBE for long 8-12 minute video clips of LCD monitor disassembly or LCD monitor repair to find out what the major cause of your monitors SYMPTOM that you described above. Here is a small hint for you. If you didn't see the displayed data on the BLACK lcd panel with the flashlight "trick" then you would know that the entire "switch-mode-power-supply" was in complete SHUTDOWN mode or even blown the "line-in fuse" for the monitor. Also try a visit to www. ccl-la.com/badcaps.htm and view some of their vids on repair of lcd SMPS/INVERTER supplys and cold-cathode-fluorescent-lamp replacement. They also do the repairs and return shipping. Please rate this on fixya if this response was helpful. Bye for now. 12fixlouie

Monitor comes on momentarilly, then screen turns black. when power is turned off and back on again, screen comes on for a second, then goes black again. Is this a bad monitor?


The only problem that causes the power on and off is a bad power supply. Go onto http://www.ebay.com and search for the monitor (power supply). My dad's old LCD screen had a bad power supply, but I found my old printer power cable (HP PSC 750 All-in-One Printer), and the monitor turned on successfully. It's not a bad monitor, unless the PSU hookup is like the PC ATX/Baby-AT PSU cable, then it might be the issue. Monitors before 2004 or 2005 have the ones, like the HP PSC 750 uses. The monitor is either defective, or the power supply is dead.

p.s.: check the voltage, amp usage, etc. on the PSU for the monitor for better results.

Monitor displays image for second and displays black again


Your Monitor has a heat sink issue. A capacitor in the monitor is at fault and when it heats it tells the monitor to turn off the display to save the display from damage....Problem Cost to repair will supercede the cost to replace it...Wal-mart 15" monitor 119bucks --17" monitor 129...same at staples office supply (Poof) problem solved.

Gateway FPD1975W black 19 inch LCD


most likely is the power supply in the monitor.
gateway LCD has a building power supply in the monitor. it supplies 38W to the lamp.
since there is no display, it tells me that there is no power to the monitor.
if try another monitor and it works fine. then the problem is the monitor. (dispaly lamp is good for 17 Years- according to the tech spec.) but the power supply is pushing too much power.
other vendors max power is apporximately 30W.

make sure there is nothing behind the monitor and has good air flow. Since there is no fan in the unit. it need to vent the hot air natually.

Acer al1714


The problem may not be the monitor. Acer AL1714 is known for its weak power supply unit. Unplug power supply from monitor. If the green light on monitor comes on but goes out quickly, the power supply is the culprit!
