m40/45 does anyone have perfect lcd backlight?

post #1 of 32
Thread Starter 
Ok so i have this patch of white light on the bottom half of my screen, to my knowledge this is "normal", mine is quite annoying as colors start washing out halfway down the screen, i can tilt the screen but it is still somewhat washed out and the top half is totally dark since i've tilted the screen. more back. the tech guy said could be the something or other cathode tube? in the screen that needs to be replaced blah blah. so tomorrow im gonna check out a toshiba repair center and ask them about it. But to my knowledge all they will do is replace this 1 part, nothing will actually be "fixed".

Does anyone have any experience with this or am i crazy.

I ended up trying (3) m-45's.
All 3 had scratches on the screen right out of the box.
The first had a perfect screen (other than the scratches).
The 2nd and third had light leaks all around the edges.
After having owned a Toshiba in the past, I was disappointed in what seems to be quality control issues.
I just don't understand how 3 different units from sealed boxes could have scratches on the screen.
I ended up buying a new HP-DV4000 and have had great luck with it.
No scratches, great colors, and no keyboard flex.

just talked to a tech at a repaire center, he told me almost all the laptops he's repaired have that, usually toshibas have that light coming form the botom of the screen, he said cause this is the source of the light, there are no bulbs on the top.. why are the screens perfect in the store? no idea probably a combination of lighting magic and store lighting. its all an illusion. The only perfect screens i have seen are sony's, but its too late for me to return my toshiba, next time I know to get sony. I saw the hp's in the store they are ok but they still seem to have bright illumination from the bottom, i dont know why sony is the only one that doesn't.

wow 3 m45-s thats terrible, i feel your pain. i dont seem to notice any keyboard flexing yet which i hope is a good thing.

I would say that I have "perfect LCD backlight" on my M40-YP3. In fact, I'm quite pleased with the quality of the screen, and I've heard only good things about other M40 screens on this forum (until now).

perfect? may i see a picture, perfect would be no light on the bottom of the screen when the background is black. I've been through 2 screens and have this problem. Try viewing it in the dark , if its perfect with black background in the dark then you need to tell me where you bought yours from lol. could be cause mine isn't the canadian one? i got mine from the toshiba site they should all be the same right? well i dont know

These pics should explain more of what im complaining about if anyone doesn't understand. Things that appear at the bottom of the screen get washed out, its pretty annoying.

is there lots of keyboard flex on that model dave, if u press on the keyboard do u see it sink

I see the problem, there. Another post of a full M40 review is floating around that has similar photos, same screen saver, plus gaming, but seems to be free of the backlight bar. (titled M40 review by ALKY)

yah i saw alky's pics before buying this actually.. also in the stores the m45 models seem perfect, but i noticed they were "display" models? maybe these display models were made in canada? im gonna call tech tonight and see if this is normal, are all of these computers made in the same factory? is it possible i can send it to canada or something in case it turns out all the US versions seem to have this problem.

masterq: i don't really notice keyboard flex but i hear rattling on the bottom left hand rest when i tap it, also rattles if i type alot on the left side, its no biggy ill ask tech about this too. i'd rather have flex than a messed up display though.

other than my pictures i havent seen anyone with the same problem either but the tech guy i talked to at kis computer center said its common on toshiba's and anye laptop he didnt specify which models though. I have the feeling this is a US manufacturing thing, if so i hope i can get canada to fix it.

Davez82,
My screen definitely lacks the glowing lower edge seen in your pictures. A complete black screen on mine looks solid and consistent. I don't have a camera, so I am unable to post any pictures.
Perhaps it is indeed a difference between the American and Canadian versions, or perhaps it is a matter of when the laptop was manufactured. I purchased mine back in April (an M40-YP3).

i just called the toshiba tech, i even showed him the pics, after putting me on hold he told me this is normal, i did tell him the canadian model does not have this problem and he told me the american one and canadian versions are not the same and have different part numbers. I aksed if it was possible if i could have canada swap the monitors, he wasnt sure but he told me it was unlikely they could do that. I said well all m40's have the same casing/ screens , he said they may look the same but they are different, even the screens. I asked him how many light tubes the monitor had, he said one at the top and one at the bottom, i said the top light seems fine, though i do not see any light from the top which leads me to believe there is none, i asked him if there was a way to adjust the bottom light , he said theres no way, well how bout replacing the bottom light with the top one, he said thats not possible either

Maybe i will call the toshiba canada and ask them if this is possible, in the meantime ill continue to try fighting for a return.

I remember seeing the m45-365 in stores which had a perfect screen which activated me to buy this computer, obviously now i understand the US m45-365 is probably a canadian made m40, while the submodels 265/165 are american made, im also guessing the casing for the 265 is the same casing made for the custom m40's. If this seems to be the case and i cannot get a return i will have to rid this cpu as I am a graphic designer and bad screens are useless to me..probably give it to a family member, otherwise i will try using this computer, but its been 2 weeks and it still bothers me, especially when watching dvd's. The only angle that seems even remotely tolerable is if i tilt the screen back 45 degrees and that is just stupid.

if i was just someone doing email or typing up reports i probably wouldnt mind but im in an industry where color is important on the screen especially if i wanted to show a client my work on my laptop and it looks all washed out. And it makes dvd's annoying to watch. Its like bieng sold a lexus with a dent in it. Im not blaming toshiba as it seems toshiba.cda seems to be doing things right, i blame the cheap tactics used by US markets nowadays, especially dell, seems like cheap manufacturing is slowly makings its way in america and the quality of products are degrading fast. Will i buy canadian toshiba if i can get a return? very unlikely, ill look into mac or sony a bit more when this whole thing blows over, most likely i will try to live with this laptop for a few months then give it away but i will not reccomend toshiba.usa ever.

Dave, now that I know that there are two bulbs in there I'll bet I know what's happening. Your top bulb is likely burned out or not working for some reason, making your lower bulb burn much brighter. Depends on the bulb configuration, but I've seen instances like this before. As far as the canadian/american thing, I could be wrong but I don't think that all americans with M40's would put up with something like that, nor do I think they'd ship all display models for stores from Canada. In fact stores generally just grab one from their stock to use as displays. I went down and took a peek at some toshibas before ordering mine yesterday(actually an M40 I'm getting) and looked good in the stores. The ones I saw though were models M45-S1691 and M45-S2691, perhaps newer revisions.

As far as quality goes for products in the US, I read an article a few months back that talked about how Americans demand a lot of customer service, to the point where companies are raising prices and skimping on things to make up for the costs involved, and it even went so far as to imply that the rest of the world pays for our customer service. I don't know though, you'd think that skimping on things would simply create a greater demand for customer service.

actually the display models i saw the stores were actually labeled, display model on the sticker left on them. This is indeed scandelous, the 265 screens do look worst than the 365 ones when i viewed them like a month or two ago, it was like two totally different computers. the 365 had a full perfect viewing angle, you would have to tilt it almost 90 degrees to see any super white light. Both of them were labeled display model on the sticker.

My guess is that the screen only has 1 bulb, the bottom one and that this was part of some design change.

As far as why sony is the only good screen in the stores now adays, the new models came out at compusa and i took a look at them, the 15 inch models , not sure how the lighting works but i do see light from the bottom, except it is not noticible when the screen is black because this light seems like its a sort of red or black light, hard to explain. Its not a pure white illumination, its kind of reddish and barely visible you really have to be staring. The top is darker than the bottom but just barely you really wouldnt notice it. perhaps these screens are only 1 bulb now i have no idea. Even if my top bulb if i have any was working properly i would still have the same problem becaue the bottom one is illuminating way too strongly, it would have to to compensate for no top bulb. The screens at the stores also denote this because the m55 has this problem too, US version of course.

This screen is also a replaced screen, my last one had dead pixels and the illumination, if even the replacement sccreen has this illumination then i think they are all like this. I see this in hp's, compaqs, dells, averatec. Seems like every notebook now has this problem, except for sony. My guess is that whatever cheap tactics dell has started using to make their notebook lcd's is now bieng adopted by all the major manufactueres, this could have something to do with overseas manufacturing or assembling, malaysia? i dont know

Perhaps the difference between models is a difference in LCD panels, there were three options for the M40. I ordered my M40 yesterday, I'll let you know if mine is like yours or Alky's, and I can also take pics. By the way, of the three options for the LCD, which is yours?

are you in canada? im america there is no m40 only m45 365 , 265,165 , 125, i think the m45-365 is gone cause i dont see it anymore, maybe the screen was too good. Mine is the m40 from the toshiba website, you can only customize it form the website.

M40-S417TD

link

the m45 has a ton of options, though at the stores hte m45 screens dont look that great either. Im guessing your at the canadian toshiba site since you said theres 3 options, only teh canadian one has that. Im sure the screen will be fine.

i ahve seen many m40's and im in canada, the screens have all been great.
post #20 of 32
Yes that's the one I ordered, M40-S417TD, right there in your US link, and there are three screen options,1280x800, 1280x800 BrightView, and 1440x900, just click 'customize'. So why is there no M40 in the US if it's right there on the site, in the link you posted?

I'm sorry, I just don't get what you're trying to say. You say the M45 has a ton of options, but on the site you can't customize at all, only a 'how to buy' and an 'add to cart'. Then you say only the canadian site has options for the M40, but the only customizeable one on the US site IS the M40. Unless by options you mean several pre-configured models to choose from. I mean options as in you get to choose the laptop components from a list.

From what I understand the numbers divisible by 10 (M40,M50,M60) are customizable and the +5 models (M45,M55,M65) are pre-configured versions of the 40/50/60. Hence you only see the +5 models in retail stores, since the 40/50/60 is essentially a special order.

At any rate, yes, that is the same model I ordered, M40-S417TD, I'll let you know what it looks like when I get it. So which one of the three is your screen?
