black screen HP ZT300 - HELP!!

Hi all...

I have an HP Pavillion ZT3000 series which i'm really satisfied with it, i've been using it for almost 3 years without any problem.

lately, whenever i open the lcd screen, a red/pink tint hows for a couple of seconds, and then everything goes back to normal..

It really didn't annoy me that much, but yesterday the problem become worse - now whenever i turn on the LCD, a strange crescendo hiss is heard, and after 30-40 seconds, the LCD simply turns off.. Well, actually i can still see something with high contrast, but it seems as if the lamp is turned off.
If i close the lid and open it again, another cycle of hissing and then turning off begins.

from some searches on google i understand it is mos probably an inverter problem. am i right?? could it be only th lamp??

The strange thing is the hissing sound, mabe it can give someone a clue for finding the culprit of all this.

Any help would be really appreciated!!

Thanks in advance.

 

Sounds to me like your backlight inverter. I doubt it's the backlight itself as you said it will work then it won't. Either theres a shoddy connection between your inverter and your backlight, or your inverter board is going.

Both are very common problems with older notebooks espescially HPs. I'm not sure how handy you are with electronics but taking it out and replacing it is a fairly simple procedure.

You can find inverter boards and cables for your model on eBay, and is by far and away the cheapest route.

Good Luck

 

Thanks for the quick reply..

I guess i'll give it a go, and buy an inverter.. they're quite cheap, and from what i ead on the net it isn't that difficult to be replaced..

Anybody else with a similar problem??

 

can it be only the bulb???

 

any other ideas guys?
