dv6000 screen wont turn on

Today I go to turn on my laptop for the first time in a week, and the screen wont turn on. The laptop turns on properly and I can hear the sound of Vista turning on, but the screen stays dark.

I tried a hard reset by holding down the power button, and that didnt work. Also tried resetting the battery but that didnt help either. Any ideas?

 

If you look very closely at the screen, can you see that the LCD is working? If the backlight has failed, then you should see a very, very dim (but working) screen.

 

Try plugging in an external monitor. You may need to use Fn-F4 to toggle it on. If that doesn't work, check this (incomplete) list:

Otherwise it's probably either a stuck lid switch, fried LCD inverter or bad CCFL backlight as Bog said.

 

Same thing happened to my dv5t only it was the first time ever restarting my computer, can hear it run, warm up, screens completely black though. Did everything you said.....hp said they'll exchange it.

 

Yes check for very dim display - cure new invertor. If all the blue lights are on and no display.

a. Has your wifi connection recently stopped working?

Answer with this series is usually the wifi chip then the north bridge chip getting too hot. They seen to warp and break the connections to the board. To repair them we reflow the board then upgrade the spec on the fans to run them faster and increase coolling.

see www.notebookrepair.co.uk

we repair about 6-10 of these a week

 

It looks like I might have this problem too. A week ago when I turned on my laptop (HP DV9590ea) I could only see the screen faintly and I have to really open the screen up for a full bright screen to come on, but if I touch the screen just a tad it goes back to being very dark and dim.

 

its a problem with the video chip. theres a recall on that issue with dv6, dv2, dv9...if your laptop is within 2 yrs of purchase you can get it fix for free by hp.
check to see if ur p/n# is under this recall http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01300427#c01300427_dv94

 

Hii

I should write something about my HP Notebook case ( HP Nightmare)
My sister bought HP DV6338se notebook. It is special notebook !!!, What a special notebook!! As HP DV6000 series have BGA chipset problem, My sister notebook went down step by step; First we lost "Wireless Adapter", Second "Lan Adapter" and Finally we lost everything, It was not working. We bought it from US but We live in TURKEY. We tried to get it repaired in TURKEY under Global Warranty. HP Turkey has not intent to repair it, so I have to repair this silly branded notebook on my own.
I have purchased mainboard from Ebay. I choose different motherboard because original motherboard (HP Spare part number 443775-001) VGA chipset was embedded Nvidia Go 6150 and its performance was too bad for me, so I choose DV9000 series motherboad (HP Spare part number 432945-001) its VGA chipset is Nvidia Go 7600 (256Mb dedicated RAM).
I thought, both mainboard are in same shape but They aren't so I had to do some work on this new motherboard
1.Second Hard Drive Port removed (It didn't fit my notebook enclosure)

2.Front side chassis, Power LED, Battery Charge LED and HDD LED and their resistors are replaced from broken motherboard (443775-001) and placed in new motherboard (432945-001). Because DV9000 series motherboard's Power LED, Battery Charge LED and HDD LED's are in additional card and mine doesn't have such a card and doesn't place in chassis to put it in

3.Caps lock LED and its resistor are replaced in new motherboard (432945-001) because LED place doesnt fit for my enclosure.

4.Touchpad switch , touchpad LED and their resistors are replaced in new motherboard (432945-001) because toucpad switch, toucpad LED' place doesnt fit for my enclosure.

5. Battery connector removed back. (That was the hardest job to do, It wasn't easy to disassemble from board )

so I thought I had completed everything but I realized that My screen back light doesn't turn off when I close lid.
I did some search in Internet and with comparing two motherboard, I found the LCD Back light Lid Magnetic Switch.

As mentioned above there are no mechanical switch inside notebook. There is only magnet in LCD enclosure and magnetic sensor switch in main enclosure.
magnetic sensor is 3 pin electronic part. It is like a BSD type transistor. I have look with magnifier and it's part number " FD720 " It is located , just above external VGA port ,in motherboard.

My new motherboard doesn't has this part so I remove it from my broken motherboard to new motherboard.

I will try to attach pictures to show you,

Now it is working very well.

When I got problem with HP DV6338 notebook, I did some search and learn that I am not alone. Too many people are struggling HP notebook problems. With my experiences, I learn that, HP is not good at producing notebook, They are good at producing printer only .Other problem is that, They do not care their customer.I think that is main problem for HP.Every electronic stuff may go down or broken but good companies provide good,fast and reliable solution for their customers. I am sorry to say that but HP doesn't provide.

I hope these information's help others.
