If you even manage to find some, I am almost completely sure it would be better to buy a new one when it comes to finances. Putting these parts together is a skilled technique. Also, if you have a guarantee with that monitor, why not return it.

It sounds like a backlight or inverter problem. You can verify this by using a bright light to shine on the screen surface. If you can see the picture (but it will be very dark) that means that the backlight which illuminates the screen from behind. You would have to replace the inverter to test it, but there is good news: These are pretty difficult to find parts for, and not an easy repair for an amateur; acer products usually have a 3 year warranty on the backlight/inverter system, so I would start there.

Hi, I have hp pavilion dv2500 laptop. I have display problem.pls help how to rectify it. If i connect exteranl CRT monitor Display is coming . Pls tell me how to disassemble the laptop.


You might have either a faulty LCD cable or screen inverter board.
The LCD cable transfers data signal from the motherboard & video card to the LCD screen. It also supplies high voltage DC power to the screen inverter board. The screen inverter board works as a power supply for the backlight lamp mounted inside the LCD screen. It converts low voltage DC power to high voltage AC power needed for the backlight lamp.

In this service manual, you will find an illustration of how to disassemble the laptop & replace either the LCD cable or screen inverter board:

The screen on my HP compaq nc8000 laptop goes blacks usually after the screen has been closed. the screen is very dark after is hardly visible except when squinting. does anyone know what the problem is or...


The culprit will be the inverter board of your LCD screen that drives the backlight, my nc8000 shows the same symptoms after 6 years of heavy daily usage. After pressing the LID sensing button near the right hinge the backlight usually remains on, but sometimes you have to press it several times under a minute once it finally stays on. The proper fix would be to disassemble the screen and replace the inverter board, as the LCD and the CCFL backlight tubes are perfectly fine in my case.

On how to remove the screen from the laptop, you can get help from this HP guide:
http://bizsupport.austin.hp.com/bc/docs/support/SupportManual/c00803690/c00803690.pdf
(it's in section 5-35, that starts on page 128)

Unfortunately, I can't help you out on the other part, on how to disassemble the screen itself (but I suspect it has 4 or 6 screws under the rubber "feets" on its front), and I can't help you out in fixing the inverter board itself either...
If you want to fix the board yourself, you have to be able to wield the soldering iron perfectly, and your goal will be to replace some capacitors (they are usually bulging, so you can identify them being the culprit by the naked eye too).
The other option is to order a replacement inverter board, and simply swap the bad with the new one, it is still more economical than to buy a new display assembly as a whole; some chinese manufacturers are available, but I bet you can find some source more closely to your current location, just google for:

EVERY TIME THE LM2201 MONITOR IS PLUGGED INTO THE ELECTRICAL SOCKET, IT MAKES A HUMMING NOISE?


ruth_coleman, Only a guess but I would say that the "switch-mode-power-supply" or "backlight inverter power supply" has a problem. Is screen always BLACK? how old is unit? How many "ON" hours on this unit? Is unit new? Out of warranty? Did it ever display a PERFECT IMAGE on it? When? Did it always HUMM?? FYI check out VIDEO clips of LCD monitor disassembly and repair on YOUTUBE to find out what is inside a typical LCD display. You will have a better handle on what to do about getting it repaired or to trade in for new. Yes, monitors can be REFURBISHED with new SMPS/Inverter boards for $50-$100. Check out some ADs here on fixya. I'm louie12fix on fixya or lmistyrel@aol.com please rate this response and get back to me if you need further assistance. Bye for now.

Backlight failure HP DV1010


You need a new screen or inverter, depending on the problem. You can't replace the backlight itself because it is build into the LCD panel. Using a mercury reaction, it makes light. Because of the mercury, it is also dangerous to replace.

Sounds like your backlight or inverter is on its way out. You can pick one up on ebay.  Google how to check backlight/inverter issues with your model.

Flickers and goes black


No it is not a backlight it is the inverter board which sends power to the backlight most likely cause is bad capacitors on the inverter board. this wil require soldering to repair backlight is even worse it requires you to disassemble the lcd unit. if you are gong to ope up the lcd monitor look on all pcb boards for deformed (blown) capacitors replace those with identical ones from yur electronics shop9they must be exactly the same mfd (Microfaradays) and Voltages
