Before going to replace CCFL check the inverter of the CCFL. Normally the inverter get faulty. There is possibility that the winding of the high voltage transformer get shorted or its driver transistor may get faulty. check the same

I have a LG Flatron L1718S; the screen display for 2 sec and then turn Black.


If the power light remains on after it goes black, the problem is the inverter board that powers the back light behind the screen, the cause is usually bad capacitors. To fix it, the board must be replaced or attempt made to repair the inverter board.

I have a 19" Viewsonic VX922 that I replaced the


This is indicative of either / or CCFL back lamp or inverter.

The CCFL is a Cold Cathode Fluorescent Lamp and the inverter changes DC to AC and functions a lot like a ballast for the CCFL. You'll probably end up buying both - unless you know for sure it is the lamp or the inverter ahead of time.

Prices vary on size of lamp, etc. Most suppliers offer both the lamps and inverters and have pages to assist selecting the correct CCFL & inverter online - one such is here. There are others, too.

Please rate my reply - thanks & good luck!

I have an older desktop Dell computer and it turns on for a sec thenthe screen goes black you can still se it faintly. I was told it might be a capasitor but I opened it and checked the inverter and see no...


How did you check the inverter?
If you get a "very-dark" image, then the most-likely cause is a non-functioning inverter.
Buy a replacement (on eBay????) and install it.

Hi, when I turn my computer on the monitor shows image briefly then turns black, it stays this way until I turn the monitor off then on again, what is wrong with it?


diva_5, You will need to use warranty first. If warranty not option, You or qualified electronics technician will need to repair the "switch-mode-power-supply"/"CCFL inverter supply" so that the CCFL tubes will stay lighted for another 2000 hours. That's my best guess. Do some reading in my and other fixya lcd monitor tech's profiles for lots more info on this very common CCFL back-lit lcd monitor problem. If reading and DIY repair isn't your thing, then skip it and trade-in unit for new. DIY repair can sometimes cost less than $10 if you have tools and know how to solder. Contracting out the work will cost upwards of $40-$70. Read before you do anything about your "black" or "blank n black" screen monitor!!! Good kuck with repair. 12fixlouie

Hi
I repair monitors
Based on other models , it sounds like you are having a powerboard-inverter issue.
It just so happens that I hjust got one in that's doing that, I should know in a day or two (maybe sooner) what the whole story on this model is.
Good timing !!??

Monitor is blank/black


It is probably the inverter board inside the monitor.
(if the screen does properly display ever then it is not the screen)
It CAN be fixed but I do not suggest anyone open up a monitor (LCD or CRT)
who is not "technically inclined." If you really want to fix this
particular one then take it to a local tech and get an estimate first. If it's almost as much as a new monitor then buy a new one.
