screen swap

Folks, I just installed a new 1080p screen on my alienware m17x over my 1600x900 one. I dunno if I did something wrong but the alienware logo that goes on the screen (the written one) worked for a while but went black after a few hours of usage. Any ideas?

 

check your cables? Might be that something came loose.

 

common issue.
Did you pull the BIOS battery when you swapped out the screen?

If you didn't chances are you broke it
If you did, its software related.

Search the forums, you are bound to find tips on how to get it to work again.

 

Yep. From recollection, there is a separate cable for the LED Logo on the panel - chances are it's worked free/loose. Wouldn't have worked at all if it was software related.

 

Gee, I didn't pull it out... I only got the main battery disconnected during the screen disassembly.

It's strange for me though that it worked for a while before blacking out. I think I broke it then?

 

I see. Do you think you could point it to me on the disassembly guide I followed? Here's the link: http://forum.notebookreview.com/alienware-m17x/587741-m17x-r3-screen-disassembly-guide.html

 

I could have been mistaken about there being a separate cable for the logo on the M17x R3 - there is on the M18x. I looked a thte M17x R3 documentation and it doesn't indicate a separate cable: Documentation so maybe you just need to ensure that all connections illustrated are firmly connected.

 

They are separate indeed.

 

I see... maybe the cable that turns on the written logo light on the screen is loose. Could you please confirm if the cable we are talking about is the right one on the right pink circle of this image?

The left one would be the WIFI cables (with pretty high end Half mini wifi kaart:thumbsup so i hope he says the right one

 

Yep. The right circle is the display connector.

When I said there was a separate cable for the LED "Alienware" logo, I was referring to my experience of the M18x, which has a separate connector for that - see here: Documentation

What I couldn't see on the M17x R3 was the same kind of separate cabling for the logo - maybe it's "all-in-one" on the 17x but I couldn't identify a specific "separate" cable for the logo on Dell's documentation for the M17x R3.

 

Don't spread false information...The CMOS battery being left in will NOT damage anything.

 

Holy a light up to the screen and see if you see anything with it on. That will determine if it's just the backlight out or not. Sounds like a defective LCD to me though, to be honest.

 

Ow and i guess you are the expert?
I am just relaying what the sticky thread says.... And what one of the(not sure if is) moderators (Katalin_2003) said that was a manditory step when i asked for help when swapping out my screen....and where other people HAVE damaged their screen...

Please, go on about this "false" information that i am spreading...please also post this at the other people that posted with end result damaged screens @the internet.

If you don't agree then state your case, yet you just make random comment.....that would explain you post count numbers.

Sorry @steviejones133 for his and my comments.
cant have someone bashing without stating my case.

 

No need to apologize to me, I'm not a moderator - we all try and help each other out here, sometimes information can be misinterpreted. The best thing to do when working inside your computer would be to do a power drain (hold down the power button, whilst the main battery and AC are out) for 30-60 seconds to dissipate any current still in the mainboard. This would nullify the need to physically remove the CMOS battery. Bottom line is that removing/performing a power drain is basically the same thing - so, you could argue the removal of the CMOS battery is rather a mute point, if the power drain has been done. Leaving the CMOS in, without a power drain could potentially provide a current spike, which may lead to damage - probability? - unlikely - could it be a risk? - yes.

So, in essence, you are both correct.

 

I ment sorry @ LeWZ !!!!!

Did you manage to sort out the problem?

 

That one is the LVDS cable.

 

Yup. I think what he's trying to find out is wether or not there is a separate mobo socket or cable specifically for the LED "Alienware" logo on the LCD - like there is on the M18x. I looked through the 17x manual and couldn't identify one so I assume it's "incorporated" into the LVDS cable on the 17x (but I could be wrong). If you check the M18x image below, you can see that there is a separate cable (in red) for the logo and the LVDS cable (green) for the display itself.

 

Everything but the written logo on the screen is working, so I'm kind of delaying the screen disassembly a bit until I'm sure I can identify the issue for good.

 

Yes! That's exactly what I'm trying to find out! Thanks for the m18x image with that detailed explanation.

The funny thing about it is whether the LVDS cable is integrated with the Alienware logo on the screen cable, how would you explain one of them working while the other is blacked out?

 

Maybe if the cable is incorporated, the part that carries the signal to the logo could be damaged - that's the only thing I could think of.

 

Makes sense. If what you said is correct then there's little to be done. I'll reopen it soon and mess with the cables a bit more, see if I have any sucess turning the written logo on. I wish it'd be a separate wiring like the one on your m18x. Things might have been easier that way...
