Grey/darker spots on my lcd = dying?

I recently noticed that when I put my laptop's lcd brightness on minimum level to save energy, that I have 3 darker/greyish areas on the bottom of my lcd when I set my screen's brightness level back on maximum.
It takes about 20 seconds longer for those greyish area's to become fully lit like the rest of the screen.

Does this mean my laptop lcd is dying (almost 3 years old btw). Also, how can I slow this down? Shall I keep my screen on maximum brightness, instead of putting it on minimum brightness when i'm afk? Or do you suggest I just close the lid, which makes my laptopscreen shut down, to limit as much use as possible.

I just bought an external screen (for 170€ which is cheaper than buying a new internal lcd (which costs 189€ at replacedirect.com without the replacement fee), so I don't want to spend another cent on this laptop.

All comments are much apreciated!

 

Your CCFL backlight is dying. 3yrs is a good lifespan for one IMO.

 

Adjust your power settings so that the laptop doesn't sleep when you close the screen. Close then screen when your using an external monitor. You can also just set the laptop to only display to the external monitor.

 

It's slowly dying. If you don't mind the dark spots you could still use it a lot longer.

 

3 years a long lifespan? I did use it the laptop for an average of 4-10 hours a day though, but didn't realise ccfl screens are so bad, I expected them to last for 5 years at the very least.

Does this mean my newly purchased TN panel will also die after already 3 years?
And how about the new laptops with led backlight displays, will they die this fast aswell? It seems newer hardware has shorter and shorter lifespans

Nyway I turned my laptop screen completely off while using the external monitor (which will be 99.99% off the time), I just hope I'll be able to use it for a couple more days during my exam periods for the next 2-3 years (which in total won't be more than a month or two when you sum up al the individual days) when I write papers and watch powerpoints in bed (where I can't be disturbed by annoying family).

 

If your new panel is a good quality one, yes, you could expect it to go about the same amount of time before showing the same dimming effect. Though I have to say LED backlights are supposed to have the same or better lifespan, without dimming over time.

 

Here's some information on LED's:
LED's do dim. In fact they dim to about 25% their original brightness in about 25,000~ hours~, of course there's no way to validate this claim by manufacturers. They actually carry a longer life time then CCFL, depending how you take it.
LED's produce more heat, and use more power then the standard CCFL design. How are they attributed to lower power consumption? Simple. They are lowered in numbers (less LED's). Of course this becomes hard to do in LCD screens, because the smaller amount of LED's the harder it is to diffuse/design to give even lighting all across the screen.. (Remember diffusers are used to even the light out in an LCD). This is why you can see some CCFL screen being considerably brighter then LED screens. Of course LED screens that are brighter are producing/consuming more heat/energy as they are utilizing more LED lights..
LED's do have the opportunity to be brighter then CCFL's, however they require a large number of LED's, and or high quality LED's. In either case higher power consumption/heat is present.

Over all LED's are the better choice, provided it won't cost you extra.
Over all LCD's are quite inefficient. But they're cheap, and look great. So meh.

 

Ouch thats really disappointing, are there also panel that will last me 5+ years? I remember my old screens worked perfectly for a very long time(untill one of them smoked and when my dad used the same cable on the other monitor...we got like 1/3rd of the screen covered with dead black pixels).

But I guess that if such screens exist, they will probably cost twice the money, if not more. In which case I might aswell buy a new screen every 3 years since it will be cheaper that way.

 

The good news is you don't have to replace your whole screen to fix it. Just the CCFL should cost $10-$20, and then your time to disassemble and reassemble the machine: CCFL Replacemnet Backlight|LCDPARTS.net

Don't replace what ain't broken the LCD itself works fine, and that's the most expensive part.

 

And usually the better option, as you must be careful on what kind of panel you get off of ebay. There are some really cheap quality ones. I agree with Pitabred, replacing the CCFL would probably be a much better idea.

 

Is it hard to replace CCFL lamp by manual? or any suggestion cause I had exprerience to open the LCD part but I can not finished the reassembly it again

 

LCD CCFL lamp replacement is possible. However would require taking apart the LCD, which is still possible just not recommended. LCD's a very sensitive. :|

If you feel up to the task, and after you do some research give it a try.

 

I agree.. its quite difficult unless ur well versed in such stuff.. also the CCFL lights are toxic so be careful not to break them.

 

Just like any fluorescent light. A minuscule amount of mercury, much less than normal CFL's like you put in your house. Just do the install over a hard surface without holes on it (table, in the kitchen or garage or something) where you can easily ventilate the area if it breaks. Sweep it up, triple-bag it in heavy plastic bags, turn some fans on and open the windows for as long as you can (a full day if possible without it getting too cold, otherwise just keep it open as much as possible for a few days in a row). Keep kids and pets out of the area, and you'll be fine.

My parents used to play with mercury with their bare hands on hardwood floors. As long as you aren't inhaling the contents of multiple fluorescent lights, you'll probably be fine.

Just be careful, and if you're not used to working with delicate electronics then you may not want to do it. But if you've got a deft, delicate touch then you'll be fine.

 

^And how it came apart is exactly how it goes back together. I video the teardown if I think it's going to be pretty complicated.

 

yes very complicated to handle this job..my LCD become useless cause of I am not finished to reassembly it..

 

mate at least u can repair ur screen.. mine is so screwed that i don't know what to do with it.. i think the whole screen or the entire screen cable needs to be replaced... good thing i'm getting a G73...
