Having problems with your HP Pavilion dv5-1250us Notebook ?

HP Pavilion dv5 laptop screen keeps blacking out. I have to move it back and forth to get the screen to come back on... sometimes it takes a few minutes to get it in a position where the screen appears again. Other times, the screen shakes or dims out of nowhere. What could be causing this and how do I fix it?


Answers :

You have either a broken wire in display ribbon or a loose connection at the motherboard.It probably developed from opening and closing the display.Sometimes the wires will get in a bind at some point and break a wire or pull it loose.You could try and take the front portion in front of the display apart(make sure it is unplugged for a bit)and check for that bad connection.
You could have a faulty inverter or a CCFL lamp, To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Display dims I have a three year old HP DV 8110US Pavilion and it has recently started to go dim or pale with slight lines. The problem is intermittent and moving it to the almost complete open position sometimes gets the screen back, but recently I have had to twist or flex the screen. It would not seem like the display or even the backlight inverter would be bad if I get the display back often for hours at a time. Has there been any issues with cabling or connections on these things? Also wher
