HP DV1000 screen too dim


The 4 most common problems with dim lcd's on a laptop are boken screens, bad power inverter, bad florescent bulbs or a broken cable.

You can test the power inverter with a meter.

There should be 2 bulbs. If your screen is dim and your inverter is good and you can still make out what is on the screen, you probably have a bad bulb. If you can't determine which bulb is bad you'll have to replace both.

In my opinion, the easiest way to handle this is to replace the whole screen. Yes, it's more exspensive, but consider that it is most likely to fix your problem. A replacement screen comes with the power inverter, both bulbs, and the cable; already assembled and ready to install.

Hp dv1000 no backlight, repalced inverter, still no screen


plug in a monitor in the side of the laptop if it shows up then the lcd is bad. Also try and reset the memory by pulling it out and then put it back in if not in all the wall nothing will appear on the LCD.

LCD screen barely visible on my daughter's C610


You need a new lcd screen.There is no bulb to replace. Try ebay,that's where I get most of mine. To replace it, just take it apart the same way you changed the inverter.

SCREEN SUDDENLY WENT DIM


One of 2 things happened....
1) You Blew the Power Inverter... The Power inverter is a thin rectangular circuit board that plugs into the display panel cable and also powers the LCD Bulb.. If This Part Fails - You Lose Light to the Display even though the display will still be on and viewable against a bright light....

2) The LCD Bulb is Faulty... When the LCD Bulb Fails it will typically give pre-warning signs- though not always.... It will give signs like the whole screen has a light orange or pinkish tone to it, but eventually it will blow and no light at all to the Display Panel....

Both Of These Are Repairable....

The Power Inverter Can Be Purchased Off of Ebay, For Around $15 to $30

The LCD Bulb Itself is also Replaceable.. Though It is a Job Only to Be Performed By An Experienced Laptop Tech... Bulbs as well can be bought off of ebay for a few bucks..

Hp Pavilion dv1000 Black screen


It is either the inverter board or the bulb

If it looks pink in color than it is the bulb and that can be quite the intensive project to replace

If it is the inverter board than that is not so bad and you can pick up an inverter board on eBay usually for around $10 to $20 and that usually installs right under the LCD screen (usually screwed to the LCD screen)

The inverter board is what powers the light bulb the data cable is totally separate function.
If you can see data on the screen with a flashlight but there is absolutely no light coming from the screen at all ever than it is probably just the inverter board

But there is a possibility that you could order the inverter board and have it turn out to be the bulb and if that is the case then unless you are very comfortable taking apart laptops then maybe a new screen would be best since you practically have to take apart the LCD to change the bulb.

But screen cost around 100 to 150 on eBay so if you decide to do that then might as well try for a deal like this: (I just spotted this on eBay and it is for entire new top half of laptop with glossy screen and inverter board wire harness and all for the same price or less than just the screen http://cgi.ebay.com/HP-dv1000-Pavilion-14-1-BrightView-Glossy-LCD-screen_W0QQitemZ310102538774QQihZ021QQcategoryZ31569QQssPageNameZWD1VQQrdZ1QQcmdZViewItem#ebayphotohosting

That is guaranteed to solve your problem for sure.

To CHange the LCD Bulb, You Can Order One On Ebay..
Just Go To Ebay and Type In .....

To Replace The Bulb...
You Need To Pull The Front Bezel Cover Off (first Unscrew it)
hen Unscrew the Side Connections holding the Display to the Back Cover....

Then UnPlug The Power Inverter Plug and Display Plug From The Little Power Inverter Circuit Board..
Be Careful Not To Bend The Power Inverter

Then You Unscrew And Remove The Metal LCD Bulb Cover from the bottom back of the Display, and You Will Need To Use A Razor and Cut The Tape Carefully Along The Whole Bottom Seam and Halfway Up The Sides.....
Unscrew The 1 or 2 screws on the sides of the display to be able to pry the frame apart and pull out the LCD Bulb.....

The LCD Bulb Will Come Right Out Along With Its Protective Metal Casing and Power Cable (pink and White).....

Just Do The Reverse To Replace.....

My LCD screen is only 10% viewable


If you have a LCD Monitor check the external video port. If that works fine chances are you either need a new inverter ($70-150+) or a new LCD ($400+).

Suggest taking to a local repair center for accurate diagnosis.

Screen Black can barely see images when boot up


One of four things possible, bad lcd bulb, bad inverter that powers the bulb, or bad mainboard that powers the inverter (rare problem).... and sometimes, bad lcd cable, also rare.

To test, you need a good bulb to plug into this inverter and see if it lights. If it doesn't, then your problem is most likely a bad inverter board. Simply shop online somewhere like eBay to find a replacement. Generally they cost around $30 USD shipped. And you can find it located in the lid, at the bottom of the lcd. You will need to remove any screws in the plastic bezels and carefully pop the bezel off to gain access to it.

 

One other thing I should mention, I have seen some laptops that have an lcd cutoff switch, or hibernate switch. When you close the lids, its will either put the laptop into a standby state, or it will simply turn the backlight off on the lcd. I've seen those switches get stuck. Note - not all laptops have them.
