Hi

I have a HP G70 laptop which im having some problems with, and would appreciate some help please.

The screen suddenly developed a vertical line around 6 inches from the right side, it reaches from top to bottom, also there are a few red lines that are like wavy lines running horizontally across the screen.

When connected to my plasma tv via a hdmi cable, the picture on the tv is fine.

i know that this model has an lcd screen and an inverter, but not sure which one of these will be the problem, from what i have read, the inverter would make the screen go dark, but that isnt happening.

any ideas please, so i can fix it.


cheers

Hi liphook27
The symptoms that you describe initially suggests a bad video chip or a driver issue but as the display is good on an external screen it may rule those possibilities out, another possible cause may be the MB to screen video ribbon which can sometimes become damaged or detached.
Repairing laptops is best left to a suitably qualified/competent person as putting the wrong sized screw in the wrong place can ruin the whole laptop, read through the attached guide to decide for yourself if you will check the ribbon out http://www.insidemyl...0-g70-notebook/

just an update on the laptop, not had time to look inside yet.

the problem has escalated though, at first there was the problem above, then when you moved the screen it would flicker and go off, you had to adjust it slowly and it would come back on, but you couldnt move it or would go off again.

now its permanently off, the screen flickers if you move the hood up and down and you see it briefly, but wont stay on.


ideas?

See post #2

does it sound more like the cable than the screen and inverter?

[phillpower2]

Yes but until you check the cable no one can say 100% what it is + checking the ribbon will not cost anything.


EDIT: It is the opening and closing of the lid making the display come and go + the good external display that suggests the ribbon.
