Hi, I recently bought a toshiba EQUIUM A60-181 and I'm
experiencing a problem concerning the LCD screen.
There appears to be a defect or dirt behind the glass
because it's blocking light from a pixel. Any attempts at
apply moderate pressure to move this dirt has failed. I was
wondering if it's common with LCDs to expect some kind
of imperfection I cannot believe this has passed quality
control. Do i have justification for having it sent back
to toshiba for fixing it's only just 1 week old ??
I've read the warranty booklet and there's no mention of
dead pixel return policy can anyone elborate on what is
and what is not covered by the warranty ??

cheers,

Richard.

Hi

In my opinion you should contact Service Partner. You bought a new product and if you see that there is something wrong you can contact them. I am sure that technicians can give you more information about this issue.

I've emailed Toshiba technical support to see where I
stand with regards to my problem. Having discussed this
issue with friends on IRC it appears I may actually have
something called a dead pixel. This is suppose to be quite
a common problem and some manufacturers can actually sell
you laptops with defected LCD screens which to me is criminal.
I’ve searched the entire Toshiba website with the regards
to dead pixel cover policy or what the warranty does and
does not cover. I understand that to replace the screen is
gonna cost Toshiba loads of money but I would have never
bought this laptop if I have been warned that it may
contain defects in the screen. I can tolerate most things
like noisy fans harddrives and scratches but not problems
with the screen especially one that’s brand new.

cheers,

Richard.

Still waiting for Toshiba to reply to my email message been
two days now. I'll try their technical support line tomorrow
at work just hope it's not one of them offshow call centres.
Anyway it appears I maybe in luck someone in the UK claimed
to have his Toshiba Satellite screen replaced in 1999 for
only one dead pixel.

However having read messages on this fourm it's been said I
need upto 5 dead pixels before they will take action so now
I'm not sure. It would be nice if Toshiba UK actually stated
clearly what's covered by warranty or not.

cheers,

Richard S.

Thanks for the info from what I can gather I have a type II
dead pixel however you can actually see the black spot with
a backlit black background so maybe this is dirt after all??
Anyway I need 2 dead pixels before toshiba will change the
screen under their warranty so it looks like I'll have to
argue my case with PC World false advertising etc since
I wasn't warned of this possibility :)
I have to say one of the first things I had noticed when I
open the box was there were some greasy marks already on the
screen which does makes me wonder if someone else had also
returned this laptop and Toshiba has reboxed it huh ??
I doubt that I'll get a replacement because there were
only two left in stock so I hope they will send it off
for repair otherwise I want a refund.

cheers,

Richard.

Hi Richard

I read once an article about this theme and in my opinion the quality standards for TFT screens are incredibly high. Can you imagine that one XGA screen with 1024 x 768 resolution need about 2 359 296 transistors. Two defective pixels for so many transistors is approximately a 0.0000847% failure rate. That works out to a 99.99991% quality standard, pretty close to perfection.

Sorry but I had to laugh over notebook “reboxing”. Can you really believe that producer do stuff like this and sold products as new? ;)

In my opinion it can be done just by dealer who sold it to you because they do everything just to sell out everything that they have. If there is an issue with the Notebook, you should go back to the Dealer, who can work things out.

Bye

I want to thank people for your input I have finally arranged to
have my laptop looked at and hopefully fixed. After phoning up
PC World technical support I nearly had a heart attack when they
said they only replace LCDs screen with 12 or more dead pixels.
I was like erm no Toshiba warrant will replace 2 or more dead pixels
and made them check the website. 10 mins later yes sir we will have
a courier sent to collect it heh (thanks Miro for that useful link).

cheers,

Richard S.
