laptop screen dead?

[saxo02]

Hi guys. Still stuck on what to do here.

 

Do you think it would be worth me getting a new screen?

 

If so could someone point me to the right screen I need.

 

Thanks again

Hmmm, I have been reading this one but not posted yet.

 

Have you tried restoring the laptop to factory settings?

 

You could buy a new screen from Ebay, and see if this solves your problem, but if it doesn't cure anything then it would be £45-£60 possibly wasted.

If a new screen doesn't work then the LCD cable may be damaged or the GPU is at fault, which also fits nearly all symptoms your having. If it is the GPU then it isn't really repairable.

 

Another last thing to try is to strip it back down and pay attention to all the contacts between the motherboard and the screen. Make sure that all of them are clean and undamaged.

What happened to the old screen? Do you still have it?

Following on from Vr5fx, I guess I would work out the value of the machine before committing to a new screen.

 

Also, we need to be sure of the screen type before pointing you in the right direction. Give Dell a call, find out which resolution screen is fitted.

Hi guys thanks so much for your help.

 

is there anyway of finding out whether the gpu is broke?anyway of testing it etc.

 

Ill give anything a try so ill take it apart again and see if theres any damage to any contacts at all.

 

Unfortunately i dont have the old screen wish i did.

 

thanks

First thing to say is I don't think there is anything wrong with the GPU, as you said much earlier the laptop works OK through an external monitor, if that is true of all functions after full boot up, it must be OK as the external monitor would show the same problems.

 

As far as something that can be done at home to double check the GPU, I am afraid the only way is with a different and known to be working screen of the same type or at least correct type for that machine, this is only something Dell can tell you from the ticket or service tag number for it.

 

Repair specialists may have the fancy but expensive test equipment, but of course may charge a fee for doing so.

 

If it does turn out to be the GPU, on laptops it is a part of the main or mother board and would require a new mother board. Not worth doing on an older laptop as the costs wouldn't be far off that for a new laptop, but as I say I doubt it is the GPU anyway.

 

I would take the advice in Synapse's last post, number 27, have a serious look at whether it is worth buying a new screen, or perhaps adding the extra and buy a new laptop, but do get in touch with Dell, and find out which screen model it should be before going further.

Find out exactly what spec machine you have - a quick call to Dell tech support will do it. We need to know what spec panel you should have.

Iv looked on dell website but there are loads of phone numbers.

Hi guys spoke to dell today about this screen.

 

They have given me a model number to which the screen should be. model number is-n7004n.

Ah great thanks very much. Much appreciated.

Ok, well......those extra numbers mean very little to me, and Google doesn't help either - normally a part number will come up pretty quickly.

 

So, what now? Well I was examining the picture you have of the new screen, part number B173RW01 V3, H/W V5A, F/W V1. There are different versions of this screen, I've seen it said that this version is for HP only, but I can't be sure at the moment. There is a B173RW01 V0, with a different hardware version, and so it goes on. Look on ebay for a Dell 1750 screen, or search for the part number and the V0 is often listed.

 

I've emailed a couple of sellers to check part numbers so hopefully one of them will get back to me. As soon as they do, I'll post the info.

[Synapse]

Dead end I'm afraid, according to the sellers, both versions of the screen work in the Dell.

 

I'm stuck with this one, if it was mine, I'd risk another panel based on the price of them, and the laptop current market value. I say that because you don't know the source of the panel you have.

 

I don't think the VGA chip is goosed as you can use it on an external monitor. The only other possibility I can think of is a faulty data cable from the panel to the board.

 

The numbers n7004n mean nothing, I can't find any reference to them.

many thanks for reply. hmm i thought n7004n made no reference either as i had a look on google etc. all they said on the phone was that number and they said it is a 17.3 wide LED.

 

would it be worth buying a new lead and screen as my initial thought it may be the lead from the screen to motherboard as in the past the hinges have completely snapped so it could have done something to the wire.

 

if so could anyone advise me a screen to buy as i want to get one off ebay.

 

thanks again.much appreciated.

Here are a couple of links, both suppliers I have used quite a lot in the past, so I am happy to recommend them. Do email them first, with the model and Dell Service Tag info to make sure it is the correct panel - if they send the wrong one for example you will be able to remind them that you did check first.

The cable, I found one in the link below, there are a few listed on ebay - again check the part number of the one you have to cross reference.
