A dim or dark screen does not necessarily mean a bad inverter! It could be a faulty lcd backlight bulb, inverter cable, inverter, or in some cases a motherboard failure.

I have a hp pavilion dv4-1430us entertainment note book my problem is that i left it without use for about 2 months then when i went to start up the laptop i couldnt and still cant see the screen it is...


do you know what BIOS is?
when you turn on any PC BIOS runs, first. (before Windows boots)
it prompts you with text "hit F10 to enter setup" or ESC key.
if that is dim and the brightness keys are dead (max = dim)
the CCFL are dead now. as all are those old.
first they go yellow, then dim then dead.
DV4 is old and has CCFL backlamp tubes that most now are dead
after 20,000 hours of usage.

the list of used Laptops or monitors not to buy or own.

the parts are not cheap nor is the labor to do this.
gander this.

Screen dim HP pavilion dv1000


The lid actuator switch may not be working correctly. It's a small switch above the keyboard and led's on either the right or left side. Try pressing it 2 or 3 times to see if the display starts working correctly again. If so, it will need to be replaced.

If that doesn't work, you can also turn it on with the ac adapter plugged in. After it boots, press the power button and hold it in until it shuts off and then turn it on again and see if the display has returned to normal.

If neither of these options work, your laptop may need to have the backlight replaced.

I have an HP Pavilion DV2000 The screen suddenly went black The drive was removed and scanned for viruses then replaced When the system was restarted the screen seems to work but only very dimly....


sure the screen is bad.
internal.
the DV2000 runs CCFL back lamps,
all go dim with age, and yellow. all do.
so can be only this.
bad CCFL lamps or the CCFL inverter driving it.
vast PCs like this are in the recycle centers. now.
endless.....
goodwill has them in piles..

Can't see the screen!!!!


Either the backlight on the LCD has failed, or the video inverter which provides power to the backlight have failed. Either way, the computer is under warranty; contact HP and have them fix it; it could get costly to do it yourself.

Screen gets dim at times.


Backlight is going bad.
Either bulb or whole LCD needs replacement.
But, first start with new/good Inverter Board.

Using a 12 to 110 inverter to power it


Check that the power adapter for your laptop supports 110V.
Measure the output power with a multimeter. If its below 110VAC (Alternating Current) your not getting enough power.

Does your computer work when its is not plugged in the Inverter?
