Dark screen/ Barely can see the desktop, I tried some suggestion of taking the battary out and changing the power manegement min to 100% , and followed all the instruction, but the problem still in pl

Hi Cindy

You have set a customer DPI scale for your display.

Right Click on desktop
Choose "Screen Resolution"
Click on link that says "Make Text and other items larger or smaller"
Click on link that says "Set custom text size (DPI)"
Adjust the scale back to 100%
Apply the changes and all should be well.

Regards
Andrew

1st try to check circuit that is operating CCFL, otherwise replace CCFL , it does not look like ccfl problem

it had been a pcba hardware issue. the cpu of that pcba is damaged. if u give 214 degree heat and 117 power of air combined for around 2-3 min anti clockwise den it will work again.

If half screen is affected it will be either a board (LCD and Plasma have different names) but in those one board drives each side of the screen unit--worst case is the display panel itself which is fatal from a cost point of view.

Your backlight bulb went out, it's a long tube on the bottom typically, It's most likely taped to the LCD frame and encassed in a metal shield. Not for the faint of heart taking on the repair. Light fixtures are found on eBay however, or new LCDs of course

Check the pins on both end of the connector, make sure they're straight other wise, reposition it with fine long nose pliers. Make sure the connectors are push and screwed tight also. Let us know!

1. Make usre you charge ur laptop for max 1-2 hours.That increase ur laptop life.
2. Take out the battary,Press and hold the power button for 1 min.Put the battary back and turn on.

signal out of range suggests that your laptop is asleep..open the display settings, and disable those, until you get this resolved.

If its very dark and you can barely see anything its probably a bad back-light. I'd suggest to take it to your local Best Buy. And yes, they can look up PSP#'s with your credit card, but even easier by telephone number.

Fading typically is related to power supply heating or connection opening on the digital drive. You might try fan into vents just to prove this, or plug in outside in the cold, and see how long it is on in test mode.
