SOURCE: monitor goes black after a few seconds

I have the same problem on my Acer AL1711. The monitor was out of warranty so I opened it up and found one of the 1000 mf capacitor almost ready to pop. A 50 cents replacement from allelectronics.com fixed the problem.

Not recommended for anyone without experience soldering electronic components to PCB's.

SOURCE: ACER AL1914 LCD Monitor goes black but green light stays on

The monitor is doing a self test a finding an error.
The lcd has three parts, the screen plate(windows)/the logic(vga)/the inverter(power plug). Parts that go are the backlight ccfl's, behind the plate, and parts of the inverter, ie capacitors, all three take a bit of power from the inverter. The self test check that all the lights are ok and the inverter is ok, else it switchs off, ie if 3/4 light work it will switch off(my own case), hence the on chech error then off, However sometime there are stages of on/off ie on/ but no screen display, if that is the case the following may be of help...if you put bright light at an angle close to lcd can you see a windows shadow, text icons etc, ie still logic power passing,then .... (from a.n. other) after two weeks searching I finally find doctor living stone http://www.aplusperfect.com/articles/lcd_capacitor_repair more fun with paulbtorrent
the takening the case bit off is like opening your wallet a second time after buying a new LCD, but you must! smallest two screw driver's flat headed, practice using two pennies stuck together()with your fingers after, one little () move and inch and {} again, with the case , it does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip inside!] also note the bright light test to do first to see if can see a windows screen , and that capacitors are one for a number of things that a make a inverter work! there a transistors as well, given that however, to replace all the capacitors on my inverter, was 11 capacitors, cost me $11 (uk ebay) and already had the iron and solder. So only cost me me $11 to try and see but no luck , still fun and I still can see the screen for 2 sec' at a time plus I have a spare set of caps now in the event that the new one do go burst! you have to laugh really, what next , a new on/off button, as you work though the whole inverter mmmMMMMmmmMMMMmmmMMMMTim Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not wellMMMMMMMMMMnnnnnnweek later land sight mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the inverter. If it went out over a slow period of time (flickering etc..) I would bet it is the lamp.replaceing the lamp should be pretty challenging. as that requires complete breakdown of your LCD, extraction of your dead lamp, and soldering in your new lamp... but I would like to say that I it did this after realizing it's 2 x kitchen strips inside [========] with wires that can connect back to the inverter with out any desoldering(ie kit assembly/dis) with the outter case remove (glass plate safe away) I could reconnect and see that 3/4 were working (i!i hardcard ) cause the inverter to switch off after a secound ! order bult and replace and going
to cheap and see if I can get away with fitting a 15" in my 19' as it a 1/3 of the price ! the market as drop out there, hope the inverter does not miss the length, or the screen out put.http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR MONITOR

Replace the high voltage transformer. It is the ballast for the backlight.. If you could pinpoint the one that's overheating then that is the one that needs replacement. Much better if you will replace the four transformer...


Hope that answer your question..
Much appreciated if you could rate this help. thanks.

Dell Latituse D600 display goes dark


Hello,

The picture board on your monitor is faulty or bad, since it goes black after few seconds, it means the picture board of your laptop has developed fault.

The best thing for you to do now is to take the laptop to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself. in order not to complicate issues.

Take care.

Monitor turns off after a few seconds. Have to


my_secret_mb, Stop pressing the ON/OFF switch! It's broke!!! The unit's internal power supply will need some work done on it. Unit will need to be evaluated first!! This is a common problem for ALL LCD monitors. If unit out of warranty period, then you will need to do some intense speed reading of my higher page number responses in my fixya profile to understand the problem your cold-cathode-fluorescent-lamp back-lit lcd monitor has and the options that you have. You will also need to base your decision on the age and total number of "ON" hours unit has seen during it's lifetime. Do not dispair or feel sad about what has happened to your monitor. A low side guess would be 50 units/day fail world-wide. Your unit may have failed filter capacitors or possible failed solder joint on printed circuit board. (thermally intermittant) I hope this helps you. 12fixlouie north of "Windy City" USA

I've got a Dell Inspiron 1525. When I power on the unit, the LCD shows the Dell startup screen, then a whinning noise and the screen goes black. Sometime shortly there after the Windows screen appears but...


This sounds more like a hardware issue. Now you say that the external display output is working fine. It could possibly be a problem with the lcd display itself shorting out. If there was a problem with the video hardware then I do not think you would be able to get the external display working either. The whinning noise could be coming from the lcd inverter.

Display goes black after 5 minutes


Repairing the DELL E171Fpc LCD Monitor with the complaint of display shutdown after few seconds (power LED still on) was not difficult. Normally when this type of problem happens, we would first suspect the inverter board, then the filter capacitors and lastly the main board. A defective in one of the lamps and a faulty TL1451AC PWM IC or inverter ic may caused the display to shutdown as well. If the lamp is defective, it will send a feedback to pin 3 or 14 of TL1451AC IC and caused it to stop producing output signal thus the display just shut off once you switch it on.
