Help- screen backlight not working!!!

I have had two of these handsets that have had the exact same problem- so now have two broken handsets! The backlight is not working sometimes (i can see the screen barely) though if i push the screen down at certain points then it turns back on which was making me think that maybe it is a loose connection? I have done countless battery pull, software updates etc and cannot find the solution?

Hello good afternoon I wondering maybe you can help me or point me to someone that can .. I'm having the same problem my back light on my IPhone 4S just shut off completely but I can hear Siri when I press the home button ... I just can't see a thing ... I've tried holding the top button and home button but it didn't reboot so I'm sooo confused .. I'm just hoping this happen to you before or you may know someone that this has happen to because I need help lol (please and thank you )

Satellite Pro L300 1AI LCD screen backlight not working

Hi All,
I have a Satellite Pro L300 1AI running Windows Vista the computer boots up and works fine but the backlight on the screen does not appear to be working.
Are there any settings in Vista that can affect this (other than the Fn key command on the keyboard and the settings in Control Panel)? Strangely it only seems to have happened since i installed Skype but I can't see how that could possibly affect it.
Any help is gratefully appriciated...

Hi
Whats wrong exactly? Is notebooks display brightness too low?
Do you see everything on the screen like behind a thick fog?
Well, usually the FL inverter controls the display backlight and if the FL inverter starts to malfunction then you would get the problem like this one.
There is no other solution as to replace this FL inverter.
Its a tiny part behind the display frame I think its a job for an ASP technician

Please help - keyboard backlight not working properly

The keyboard backlighting on my 15in early 2008 macbook pro stopped working properly about two weeks ago. I opened it at night to find that only the middle keys were lighting up. No spills, no drops or anything out of the ordinary. I have already reset the SMC (via sleep/restart/shutdown and shift/control/option/power), but no luck. Currently the only keys being lit are: 6 7 8 T Y U G H J B N. If anyone knows of a fix for this or anything else I should try, please help. Thanks.

You should take your MacBook Pro to Apple for repair.

Maverick update now my login screen does not work please help.

Hello hope you can help. I have a 24 inch Mid 2007 Intel iMac. It has been great until now. I recently did the Maverick update and now my login screen does not work. When I wake the computer up the screen appars with my picture icon. When I click on it nothing happens. If I click on it a second or third time the beach ball appears and nothing happens. I have to shut the unit down with the power button and when the unit powers back up everything works normally. Are there any suggestions out there? I have updated the software without resolution. Is this computer too old? Do I have to buy a new one?
Thank you

Your iMac can support Mavericks according to the requirements > OS X Mavericks: System Requirements
Try a Safe Mode boot. That deletes some system caches that may help.
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from the Apple () menu.
See if there's an improvement for the login screen.

Keyboard backlight not working...

Hi everyone!
I am having a problem that appears to be shared by other Powerbook users who have the luxury of a backlight for their keyboard: I have updated OSX and now the option of automatic illumination has gone from the Keyboard and Mouse preferences window?
Does anyone know how this can be fixed? I have only had my laptop for 13 months and so far my hard drive has died and the system has crashed completely three times, I would be devistated if this is the logic board now? If you think it is please lie!? Only joking of course, but if anyone has a neat solution I would love to know!
I have already tried to set-up a new user, and have removed the com.applebezelservices.plist from the library, but no joy so far.
I use this luxury lots, since I work at night. Any help would bring festive cheer to me and my children to be!!!
Regards,
Simon

Same problem here with my powerbook 15" 1.5ghz.
It seems that this problem is common with a lot of people as I can see from the forums that I went on.
The ambient light sensor seems defective since a software update (probably the 10.4.7). Results are that the auto-dim of the screen does not work all the time, the keyboard no longer backlight up in dark condition and the sleeping status light blinks for no reason or it stays on when computer is open.
I've tried to zap de PRAM and reset PMU with no results.
I've read that some people has a loose connection between logic board ans ambient light sensor... could that be the reason as you mention taht they told you so?
I've read that some people with the same problem had their Logic Board changed as they were under warranty... but for the rest of us that are not on the warranty anymore... no answers from Apple. I think that they should open a repair ticket and that everybody who has this problem should contact Apple

Lenovo b570 Backlight not working

Hi all,
Had a few problems with my b570 (think the hard drive might be screwed)
But tried to wipe it all and start from fresh, and after not being very successful left it alone for a few months.
Im trying to have another go at fixing it now and the backlight on the screen is not working, there is no real reason for it to have stopped working as it hasnt been moved in months, the screen is still working but is very dark if i get real close i can see what it says.
do i need to replace the whole screen or is there something i can do to maybe get it working again?
Thanks

hi robk87,
Welcome to the Lenovo Forums.
If you get the no backlight issue after you turn ON the computer and adjusting the brightness (via Fn + up/down arrow) have no effect then you may need to replace the entire screen.(looking at the spare parts, the B570 uses a LED-backlit LCD display - these types of display doesn't have an inverter which powers up the backlight).

Alternatively, you can try using an external monitor and connect it to the VGA or HDMI port (selected models) to get a display.
Hope you get the computer fixed soon.

My USB port (closest to the screen) is not working? And what is an IR Receiver in my USB port?

Hi everyone,
     I recently found out that my USB port, closest to my screen, is not working. Before I called Apple Care for help, I performed a PRAM and a SMC RESET, which unfortunately did not work. I called Apple Care and they help me troubleshoot simple resets such as, shutdowns and restarts. The representative I spoke with conluded that the physical hardware has an issue and must be brought to the Apple Store for a diagnosis. I called the Apple Store to at least budget the fee for getting a USB port fixed and it's about $300.00. I never dropped my macbook or had any sort tactile encounterment with hard surfaces by dropping or hitting. I don't understand how my macbook pro would be physically damaged. I then thought maybe my software was out of date (right now I am running 10.9 Mavericks) or I forgot to do the minor software updates, but I was at a lost again because my macbook is up-to-date. I searched for further help and found a way to monitor what's plugged into my usb ports. (I read in the apple forums that a girl had nothing in her usb ports, but upon looking at the System Information> Hardware> USB, that the macbook recognizes that there are drives in the ports) I looked at my ports; one is being used by wirless mouse (the port that works) and the other (the port that doesnt work) is being used by an "IR RECEIVER". Now, is the IR Receiver actually using that port and that's why my macbook cannot recognize other devices inserted into that port? Or is the IR RECEIVER suppose to be in that port and that the hardware for that port is simply damaged (which would mean I need $300.00 to get that fixed)? I know this is a lot, but someone help me?

I can help with the "IR Receiver" part of your question. That's the piece of hardware inside older MacBook Pros (MBPs) that lets them work with the Apple Remote. "IR" is the standard abbreviation for "infrared," the portion of the electromagnetic spectrum used by remotes for many common devices (stereos, cable boxes, Apple TVs, etc.). The remote sends a coded stream of IR pulses; a corresponding receiver in the target device "sees" the infrared light and decodes it. The MBP's internal IR Receiver sends the received signals to the processor via USB through an internal hub.
The most recent MacBook Pros have dropped the IR receiver and no longer work with the Apple Remote.

Help viewer does not work after update to 10.4.4

Since updating to 10.4.4 my Help viewer does not work, and all of the troubleshooting fixes suggested in other threads have not had any success in resolving this. I've noted that when I go to Users>Library>Documentation>Help there is no mac.help file - can someone tell me if that means that I've lost the file altogether and need to reinstall it? I get to the first screen of the viewer, but the links from there don't work. Thanks for any help that you can provide!

Thanks for your suggestion. I downloaded OnyX and ran the cleaning function. After restarting, I opened Help and once again the first screen appeared fine. But again most of the links did not work, though those under the "What's New" heading did work. I might add that I had previously tried a variety of suggestions posted in another thread, which included deleting from the caches folder in Home>Library several files such as com.apple.helpui and help.plist in the Preferences folder. (As noted in my previous post this evening, I also created another user but that also did not have any effect.) Any other ideas? Thanks

Dear all,
I had the same issue with my nokia 5800, finally I found very interesting thing, I have been doing everything to bring my phone back to original condition where simply I can touch and access the phone.
Actually the issue was with the thin plastic piece which was put on the touch screen for its protection. I was struggling to touch and access the phone but i coudnt for almost 2 weeks, it was directing me to bottom left corner touch buttons of the phone and automatically opens and activate functional which I didn't want.
Solution was, I simply removed the thin plastic layer from the phone , Now it works fine.
Hope this will help.

Lenovo Yoga 13 Screen is not working

Hi Guys!
Please go through my complete message as it is very 'painful' experience you can ever come across when buying a laptop.
The Lenovo Yoga is not available in Australia. So, I bought the Lenovo Yoga 13" orange i5 128GB from 'adorama.com' for US $999 + UPS shipping $105. Unfortunately the shippment attracted a custom of 185 AUD which I had to pay later. In total, I have already spent 1400 AUD.
The UPS courier service delivered the shipment to my address an hour back i.e. today on 5th July,2013. I was very happy to receive the product but when I switched on the laptop, the screen is not working properly and is displaying a number of vertical colored lines.
To confirm that it is the screen problem, I connected the laptop to my TV with a HDMI cable upon which I could see the windows display on the TV. This clearly establishes the fact that the laptop's screen is faulty.
Next, when I checked the warranty number online it shows that warranty starts from three months earlier than my purchase date which clearly shows that someone registered the laptop before.
Also, the charger I received with the laptop looks to be a used one with scratches and marks on it.
I am afraid, the product I got from Adorama is damaged and maybe a refurbished one as the charger clearly looks to be used before. I am deeply disappointed with this incident as I was very excited to use that product and also importantly had lots of work to do with it.
I contacted Adorama, and they are saying that they might exchange/ refund after seeing the product for which I have to ship back the product to the United States. They have asked me to provide a quotation of the shipment and told me that they will decide accordingly.
Firstly, I dont know how it will work out and next, I cannot trust these people anymore to refund me the money after returning the product. I am anyways losing the money I paid on customs.
Therefore, as being my fellow Lenovo Yoga mates, I request your advise on this issue to me. I would really appreciate whatever it is.
I kindly request Lenovo to look into this matter.
Thank you!
Amer

I have exactly the same problem just a set of vertical lines on the screen. Never before have I had such a pathetic problem except maybe with laptops that are 6 years old.
For further details I have the Lenovo IdeaPad Yoga 13-inch Convertible Ultrabook (Orange) - (Intel Core i7 3537U 2.0GHz Processor, 8GB RAM, 128GB SSD, WLAN, BT, Webcam, Integrated Graphics, Windows 8) bought from amazon.co.uk ( http://www.amazon.co.uk/exec/obidos/ASIN/B00CA10NUE ).
The screen lasted 6 days before dying. Just enough time for me to waste getting it perfectly set up before it died. There was nothing to indicate prior to the screen failing that it was going to fail. Turned it off one night and turned it on the next morning and the screen was only displaying the vertical bars.
I'm going to try sending the Laptop back to Lenovo. I actually managed to get through to the Lenovo support - they have quite a good system of dropping the laptop off in a local shop that is then picked up by Lenovo, they reckon to have a turn around of 10 calendar days. I can recommend trying to call the Belgium helpdesk as Lenovo can never outsource the help desk people since they need to speak French and Dutch but usually they will also speak English - start the conversation with "Parlez vous anglais?" / "Spreek je engels?" . Admittedly it will be no use if you need to return the item, but if you just need a bit of technical support it might be a good way to go.

I have recently upgraded from my iphone 5 to a new phone. My iphone 5 's touch screen does not work anymore. I need to backup my phone, but I can't do it on itunes without my password. Everything besides screen is ok. Is there a way around it? :(

I have recently upgraded from my iphone 5 to a new phone. My iphone 5 's touch screen does not work anymore. I need to backup my phone, but I can't do it on itunes without my password. Everything besides the screen is completely fine-the screen will not recognize my finger anymore. I am not trying to fix the phone, but I need to have my contacts. The pictures have already synced, but I need my password to do a full backup. Unfortunately, I can't type in my password. Is there any way around it? If I take my phone to the apple store, will they be able to help me? I am not willing to replace the screen just to do this, however, so that is out of the question.

Someone else may have a workaround, but, as far as I know, if you cannot interact with the screen on the iPhone, there is no way to unlock it so you can get to your contacts.
Were you saving them to iCloud by chance? If so, you can restore them to your new phone.
