Question about Dell E176FP 17" LCD Monitor
I also have problems with my monitor turning itself off after a 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up? The PC boots up okay and if I swap over the cables to anoher monitor it works okay, I have also tried the monitor on another 2 PC's and it works fine on them. I have also downloaded the drivers from the Dell support website but this has not been of any 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.

Hi Abbie, Sounds like the back light inverter board is bad. It's a very common problem. LCD's use four small cold compact fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino

Sorry Abbie somehow I missed that in your post.
Strange problem. Do me a favor and try the flashlight test next time it goes out on you.
Just shine a flashlight directly into the screen, like you're trying to look into the monitor. If you can see a picture around the flashlight it's a backlight problem for sure.
Let me know,
Dude
See...and you thought I was nuts!!! lol You might just have a loose connection somewhere, maybe a bad solder joint or chip-creep. Might explain why it worked on two other PC's. Did you move the monitor to test on other PC's?
I wish I could give you a concrete answer to cost. Replacing the board and or the CCFL's is simple. At worst you have to do a little bit of soldering to replace the CCFL's All you need is a screwdriver for the inverter board. Finding the right parts can be a bit of a pain tho.
I have seen the boards go for £10 on eBay and figure £35 tops new. Monitors with cracked screens but good backlight parts start at like a Pound all day long.
It really is an easy fix. I'd think an electronics shop might go £10-20 max for the labor. Know anybody handy with a soldering iron?
I searched for you and came up with no leads for your parts. Not even part numbers. Call Dell they can either sell you parts or give you part numbers so you can find them.
It's a shame, if the specs were higher on that model I might have been willing to buy the same LCD as yours, used and sold you the parts you need. I'm looking for an LCD screen for a project. I only need the screen, controller board and power sections. Hell you could have had the plastic frame and stand too as a spare if you wanted. Gonna build an LCD projector but I'm looking for a screen that can handle HDTV resolution.
LMK what happens

Why would the monitor work fine in other PCs then, if the invertor board was faulty hen surely it would always be the same no matter what PC it was connected to ???
I flashed a torch into screen and your right the picture on the screen was visible, would you happen to know what a good price would be for replacing this as it will cost me £15 in delivery charges to send back to Dell to sort ??
Thanks for the info mate
Abbie
