If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

SOURCE: IBM ThinkVision 17" Monitor displays for 1 second then black

This seems to be a common problem with these monitors. Have a look very closely and see if you can still see something there. From there, either send it to get repaired, or, if you are handy with a soldering iron, open it up and replace the 4 main capacitors (at least one of them will be "popped", but it is handy to replace them all.

In order to open the monitor, you will need to remove the stand, and make sure you get all of the screws out before attacking it with a screwdriver.
I have 5 IBM monitors at work with the same problem, and opening them up has shown the popped capacitors.
Again, only recommended if you know what you are doing. Screwing it up will leave you with nothing.

SOURCE: Monitor black screen with blinking amber/green light

You need to reset the display. The display is in a safe mode. Resetting the display is a simple procedure and Planar has the instructions on their website in their online customer support section.

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

The Dell AS 501 monitor display comes and goes off in seconds. If I switch off and on again, the display comes back and goes off again in less than a second. I repeat this as many times the same monitor...


This sounds like the power inverter is failed.. It's what pumps up the power for the light in the monitor.
You could try unplug the sound bar from the back of monitor if you have the sound bar installed. Just a maybe..
To fix the inverter (replace) is usually better to buy newmonitor unless you do it your self.
The defective LCD Backlight inverter will cause the following symptoms:
  • No Display, but Power Indicate light stay on green (Or Blue).
  • Screen flash on and off and the power indicate light stays on green (or Blue).
  • Dim Display

Here are the service manual (not usre which model you have, downloads are limit to two per day):
http://elektrotanya.com/?q=showresult&megnev=acer&megnev2=al1511&kategoria=&kat2=all
You need to do some voltage checking make sure you do have 5 and 12v. The caps the secondary DC side should all be replaced at the same time, it may look OK but they can have high ESR, and they also should be low ESR type such as FM or FC series by PANASONIC. You can send me pictures if you want more help, budmrtn@aol.com

I left monitor power on for about 2 months .when i finally noticed, it was off and wont turn on


rixwar, How many more hours of on time in addition to the approximate 1500 hrs (60 days) does this monitor have? I should guess that any monitor that fails before 4000 or 5000 hrs should be still covered by warranty. Maybe I'm lucky. My 16 yr old 32' tv is still operating after 20K -25K hrs on it. But then again it's a crt not a CCFL backlit lcd display.
You may need to repair AL1511 "switch-mode-power-supply"/"inverter circuit" in this one. Read more of my and other tech's FIXYA profiles on what to do about black or black and blank lcd monitors and for other options open to you. 12fixlouie.

I have a similar problem.
Switching the screen off (front panel button) and on again after waiting a few seconds fixes it.
This is a recent problem, so I'm expecting it to get worse and worse until one day!!!!!!
