Toshiba 44 NHM84 DLP TV - Can't turn on it

I have a Toshiba 44 nhm84 DLP tv. It is about 4 years old.
Within weeks of buying the TV It would not turn on. After turning the power on, the green light on the TV would blink for about 40 seconds and then the red light would go on indicating the TV was off.
I brought the TV back and was given a brand new one. About two months of watching the new one the same thing began to happen only some times it would turn on sometimes it wouldnt. This continued for a couple weeks and then suddenly the TV worked fine.....
Well now it will not turn on at all. Green blinking light for 40 seconds and then red light TV will not turn on. The waranty is up.
Does anyone no what is wrong with this TV? Can I fix it? What do I do?

Hi!
I agree with Horwarth. Here it is a Computer systems forum.
You should ask this in a TV forum or something else and the best way would be to contact your seller.
Maybe you will get a good offer for the repair.
Bye

How can I turn off sound controll whele on the Satellite A200

How can I turn off the external sound controll in front of laptop - the wheel? It does not work, sound volume is permanently muted.
OS: MS Windows XP
Thanks

Thank you Jaba,
it is Toshiba Satellite A200 Series. Drivers, its configuration and configuration of operating system is OK. The wheel is mechanical damaged, so that is the point. I have to disable its function in operating system. But where can I disable it? I have tried to uninstall Toshiba utilities (controls, hotkeys), reinstall drivers. I have tried to find an option in BIOS, there was no one.
btw: I am a linux administrator, but I have advanced knowledge of windows systems so you can be short.

I can't turn the Wifi on, Satellite L40-18Z

Hi there,
I've been using Satellite L40-18Z but I can't turn on Wifi.
I'm very sure that Tthe device is installed propery and I tried some ways to turn on Wifi device but never turned on. Of course, never catched the signal. Rooter has no problem either.
Deveice manager says ithe device works propery. And the driver is correctly installed. But I can't turn on from windows mobility centre or network setting.
It's very embarrassing to post something like this but I need your help.
P.S. this is the first time I post on this thread but who answers? Toshiba support team?
Thanks,

I have the same problem. Does anyone cope with it? Have my wifi disabled can't switch it on, tried to reinstall it nothing work.
Have it installed and work correctly thru device manager. Wifi can't be enabled and find network, all other devices are working properly. Access point have no limitation or something else in their settings.
Windows diagnostic can't resolve this issue. Shows that "wifi is still disabled on this computer" FN+F8 doens't wotk too.
Any help are more then wellcome.
I suppose this is Realtek RTL8187B Wireless 802.11g 54Mbps USB 2.0 Network Adapter bug within Thoshiba Laptop.
Thanks in advance.
PS
Running Vista Home Premium that goes with laptop. 100 mb network is working ok.

Satellite A660 How can i turn off the lighting of the power button?

Hello, I recently bought a new Toshiba A660-1FL.
However bothers me is the lighting of the multimedia keys, if I work in the dark.
In Bios I could turn off the led illumination, but the power on/off button is still lighting,that distracts me when i am working.
This notebook has two power LED, so the power on lighting is in my opinion, unnecessary.
My question is: How can i turn off the lighting of the power button?

Here you can see the LED with the same function in front of you: http://s3.imgimg.de/uploads/t009aae62jpg.jpg
Yes in fact, the difference is color, design, but also location and brightness of the LED.
For me, this LED is too bright and it is distracting in the dark, as you can see here: http://s3.imgimg.de/uploads/leddf570760jpg.jpg
I was today at a local electronics store, and saw that Toshiba has the brightest Power LED on A660, but why it must be placed under the LCD and not in the front as in my old notebook Toshiba A210.
I also had the idea with a tape, but it would look ugly, and it must be removable without residue.
P.S. Also the fingerprints on the glossy keyboard do not look nice.

Satellite L300 - I can't turn up the volume for a low battery

Hello dear Toshiba users
My english is not very well.
I have a Toshiba notebook L300 Satellite
My problem is that i can't turn up the volume for a low battery
Is there any one who knows how i can resolve it?
thanx
mariete

Hi
I think you want to enable the sound notification when battery gets empty.
Is it right?
Well, you can do this in Vista Power settings
I assume you are using the Vista OS and therefore this battery notification can be enabled in Vista Power settings.
Please check this Toshiba doc.
+How to handle power managment features of Windows Vista+

There you can find the settings for battery. Its called Low battery level
Check it.

Qosmio X505-870 - Can't turn off and nothing on monitor

I wasn't doing anything particularly interesting when my computer just shuts off randomly. I pressed the power button to turn it back on, I can hear the fan and the machine going but nothing appears on the monitor. I pressed and held the power button to turn it back off and try again, it won't turn off. It's stuck with the computer on but a blank screen.
Not sure what to do, I can't turn it off, and it isn't doing anything.
Might try to put the recovery discs in to see if it does anything but I'm worried about files I have saved on the desktop (stupidly)

Hi colhyena,
I agree with Akuma. The same instructions posted by Akuma I found here:
[Which steps should be followed if your Toshiba notebook doesn't start?|http://forums.computers.toshiba-europe.com/forums/ann.jspa?annID=21]
So thats everything what you can do and if its not working you need professional help from an authorized service provider.
Qosmio X505 is newer notebook model so probably yours is still under warranty. In this case the repair is for free and you dont have to pay something. :)

How can I turn my French apple account into Australian one to be able to buy a Iphoto book I've made?

hi
How can I turn my french apple account into an Australian one , to be able to buy a Iphoto book I 've created ?

And you need to set the "Print Products Store" in the iPhoto Preferences "Advanced" to the country you are in. The credit card you will be using with your AppleID needs to be valid in the country your AppleID is registered to. Will you be staying permanently in Australia? Maybe it wuld be simpler to create a second AppleID just for the time of your stay there.

Can't turn on my Lenovo 3000 N200

Hello, I've got a problem with my Lenovo 3000 N200 laptop.
Yesterday I used it without it's power supply, so it discharged. I let it charge, but none of the indicating power lights are lit up even though the power supply is good. It has now ''charged'' all night, but nothing has changed, no power lights and I can't turn it on. I'm confused, it's the first time when something like this happens, I haven't dropped it or anything it just completely discharged..
I already tried 2 times this trick when you remove the battery, push the power button for about 30 seconds and then put battery back in, but it didn't work.. :/
Any ideas or it's dead?

could be power cord or mainboard issue due to "no power lights"
i believe you don't have valid warranty but is it possible to contact local support center? you'll need probably some more help to diagnose the problem.

My Macbook Pro is frozen on the login page with a white screen and only my login picture. How do I fix this? I can't turn it off and I closed it and let it charge but it's still not working.

Hello Kierasully,
I would start your troubleshooting with the article below for issues of not being able to log in to your Mac. Start with booting up in to Safe Boot as well as resetting PRAM on your Mac. If that does not work, then verify the hard drive with booting to the Recover HD and go to Disk Utility to verify it.

Feedback? Did any of this help?

I bought a usb microphone (blue snowball). I can't hear any sound from it. The MIDI master volume is turned all the way down, and I can't turn it up because it's frozen/locked. Please help!!! Not very tech savvy, been at this for hours and desperate :(

I've been trying to fix this problem, seems like it would be simple, but apparently it is not. I just want to turn up the master volume control under my input tab in MIDI audio devices so I can use my blueball microphone.
This image above is what I'm currently dealing with. I put a red box around the volume control I want to use. That is the one I can't turn up because it is locked/frozen.
Please make steps as simple as possible!
Thanks

You should have gotten a user manual. If the manual is of no help, contact the manufacturer.

my adobe illustrator is in a foreign language. how can i turn it into english?

First please remember this is a public forum. If you are going to respond to the thread via e-mail please remove your signature prior to responding.
To resolve your difficulties you will need to go to the Language & Text preference pane. Once there click on Edit List and remove all languages besides English. You will then likely need to remove and reinstall the trial as the language setting I believe is set during the installation process.

How can I turn off "Find My iPhone" in order to restore my phone if forgot my Passcode?

I'm trying to restore my iPhone 4S because I forgot the Passcode. I got a new 5c but when I went back to my 4s, I forgot my Passcode and now it is disabled and it says "Connect to ITunes" but iTunes says that "Find My iPhone" must be turned off before it can be restored, but I can't turn that off if I can't get into my phone. What do I do?

u may try what kappy suggested or
donwload a stock firm ware of your iOS from any external site
switch of your iPhone
put it in recovery mode ,connect to a pc/ mac with iTunes
open iTunes if it did not open on its own
it should pop a message saying "iTunes detected a iPhone in recovery mode"
click ok or hold option and click on restore
it pops up a finder window just select the firmware u downloaded
and let the magic happen
afterwards u can sync but don't restore from a back up it locks ur phone again
