Screen problem

HSean · 06-02-2008, 07:29 PM

I got this laptop, it sounds like it boots fine the screen light comes on but nothing shows, anyone know why?

try with an external monitor. you may have a defective video card.

HSean · 06-02-2008, 08:32 PM

Alright and if it does work what should I do?

HSean · 06-02-2008, 08:42 PM

Well computer run s fine when on a monitor, aside from the mouse on the laptop. it was disconected when I got it

**TriggerFinger** · 06-03-2008, 07:38 AM

so what you have now is a laptop that works fine on an external monitor but does not give anything on the LCD? that could mean a defective LCD.

you said previously that LCD somehow lights up. does that mean you do not have a dark or dim screen? do you see anything during the boot up process (POST, cursor, logo, etc.)?

HSean · 06-03-2008, 01:55 PM

It lights up like normal but you see nothing, like theres something disconecting it or something Should I follow wires? lol

**TriggerFinger** · 06-03-2008, 03:52 PM

yup you are correct. check the LCD cable connections going to and from the motherboard. make sure they are seated well. also consider replacing the inverter with a known working inverter board (these are cheaper).

HSean · 06-03-2008, 06:37 PM

whats that thing look like?

**TriggerFinger** · 06-03-2008, 06:41 PM

first i suggest you get hold of a service manual for your model of laptop if you want to do some removal and parts replacement.

as for the inverter, most common looks like this:http://i11.ebayimg.com/03/i/000/9c/42/0efb_12.JPG

HSean · 06-03-2008, 07:52 PM

oh I saw that on my last laptop I think they are in the screen part.

**TriggerFinger** · 06-03-2008, 07:56 PM

yup... it is located near the LCD (somewhere on the top lid). the service manual will show the exact location and steps on how to remove/replace it.

HSean · 06-03-2008, 08:24 PM

I located the problem, theres a ribbon wire thing thats proberly not supposed to be cut lol

**TriggerFinger** · 06-03-2008, 08:29 PM

ribbon wire? hmmm, yup there is a flat cable at back of the LCD, is that the one you are referring to as cut?

HSean · 06-03-2008, 08:38 PM

Well it looks like it, I have the whole laptop apart now lol I don't know where that wire goes but that is the one

**TriggerFinger** · 06-03-2008, 08:49 PM

i just hope you have the service guide to help you put things back together.

i believe you can get that part from online stores.. try eBay.

HSean · 06-03-2008, 08:52 PM

I can put it back togeather but I think theres a big piece missing somehow, I see nowhere this goes
