KDL-55HX750 red light blinks 3 times

My TV no longer works, it feeds on. that it snaps and then the power light turns RED and flashes 3 times repeatedly. Please help me, cause I can't believe I have to pay so much to replace the main Board.

TV works fine. I found that I had downloaded the version of firmware USA instead of the version of the MEA. Once I downloaded the correct software copied on the USB, the TV updated Firmware accordingly.

Thank you

  • Trinitron TV turns off. The red light blinks 7 times

    I have A FD Trinitron WEGA. It works perfectly for the past year 8 and a half. Recently, he died while we watch. The red on the front of the TV blinks 7 times. I wonder if a repair is required, and how much it will cost, thank you for your help.

    Hi joehui,

    Check whether in the TV, clock/Timer is set. If so, disable the timed operation parameters.

    If the TV is connected to a power strip or surge protector, remove the power strip or surge protector and plug it directly into the wall outlet. If the problem is resolved, the problem is with the power strip or surge protector and not the TV.

    Follow the steps below to perform a power reset:

    • Turn off the TV.
    • Unplug the power cord of the TV from the power outlet.
    • Let the TV remain without power for 60 seconds.
    • Plug the power cord into the power outlet.
    • Turn on the TV.

    If the problem is still not resolved after following all the steps of troubleshooting, service may be required. Locate the centers of the closest authorized repair the link below.

    The exact cost of the repair can be determined only after a physical examination of the TV. You can contact the service centers to know exactly the cost of repair.

  • Satelite L775 used high power - orange light blinks 5 times

    Greetings,

    I bought my Toshiba Satelight new l775 7 months ago, it's so crazy. It used to be on, I use the laptop connected to the adapter 4 to 8 hours a day, then the laptop goes unused and unplugged for 16 to 20 hours a day.

    This is my 3rd phone, I know that I put more tension on the previous two (HP and Acer). I've never had a laptop go on me this quick, even this acer laptop $ 300 crossed more tension and never went out in the 15 months that I got it.

    My laptop backup is a HP of 4 years, I've had it for 4 years, its fell several times, used and abused still underway! I just had to level of ram and hard drive. But, this Toshiba! She was so beautiful when I saw him!

    I have never dropped it, never spilled something on it, so why she put me through that stress at a bad time?

    A bad time because even if I'm under warranty, I'm leaving on vacation in 2 days! I need it, I'm not trying to take my old HP that came out in 2008.

    I can't afford to send my Toshiba for 2 weeks, not immediately.

    Today, my anti-virus software was his typical scheduled scan, I didn't charge the laptop, because I was out of work, so when I leave the laptop gets used more and charged additionally. I look at the laptop and its judgment, I just thought, O... my battery died, I would plug in the adapter and do some reading. Nothing good happened. 8 hours later, I worked on it for more than 8 hours, I searched all over google, many forums, none of the following solutions worked for me.

    Disconnect the battery and press power for 30 seconds
    Unplug the adapter and press power for 30 seconds
    Disconnect the battery and the adapter and press power for 30 seconds

    (of course after the 30 sec thing, I tried turns on normally, with or without battery and power adapter).

    I pulled the little battery round, hard drive, memory sticks (even changed the 2 around and I tried each one solo) I tried without any ram. I unplugged all the excess material, the only extra things I had was my usb mouse, but I unplugged that, even pulled the CD-ROM drive.

    I removed all water-cooling, open the laptop to see if I saw something a coward, I don't see anything, the part where the adapter will seem a little loose, but it seems to go all the way and fine. I pushed hard and still nothing.

    One thing I will say... I read at least 8 other fairly new poster of Toshiba satellite owners with similar problems of their laptop does not turn on. This isn't a good glance, since this is the first product of Toshiba, that I bought it and it costs $500 more than my acer laptop which gave me no problem in my 15 months of owning...
    I'm not belittling Toshiba immediately, this problem might be a small question (I hope), I could be my fault, so I'm not belittling Toshiba again because I like a lot about this laptop, especially the graphics!

    Return to this topic after watching the discussions of people with similar problems, I noticed, nobody had the same exact problem I'm having. See most of the threads I have read, people would still get the orange light when the battery has been driven. I ONLY get the orange light when the battery is in the laptop. I try and power without the battery and nothing happens, no light flashes. Many other people were always other color lights or lights in different locations, my only light flashes 5 times, the second place left and is orange.

    The only light that blinked in the last 8 hours is the second light from the left (I think it's the power light) and it flashes orange or maybe its red light... but when I press the power (I tried holding, tapping, etc...) that the orange light blinks 5 times and stops, nothing happens I don't hear any readers of spinning, everything is just dead.

    Thanks for the time and help!

    Hi a8000

    Looks like you already tried all possible solutions
    The flashing light indicates that there is a possible hardware failure, but it is not possible to say what part is malfunctioning, it might be the motherboard
    However, the guarantee seems to be valid so don t waste time and report it to the service provider in your country, they should solve this Toshiba!

  • Aspire V5 on used to be able to. Power light blinks 5 times.

    Daughter finally used the laptop on battery and ran down id by pulling it completely until the computer turns off. She plugged the power cord and it would not come when you press the power button.  Laptop has been plugged in overnight and this morning same problem - just power light flashes five times when you press the power button. This is the same behavior so plugged in to the power supply or not. I tried holding down the power button. Tried with battery removed and a/c power, but then no light at all.  I tried removing the battery and the power of the a/c, press and hold the power button for 30 seconds, then install the battery and plug in power a/c, but no difference.  I tried another a/c adapter and no difference. Any ideas?

    I had an object hold down the power button on all day.  Now I plugged in the power of a/c, and it began immediately.  Problem solved.

  • BlackBerry 8900 smartphones will be no more power up and a red light blinks!

    I have a new 8900 and put in place all OK.  It now will not power and all I have is the red light flashes intermittently. Have tried removing the battery but no joy.

    Someone at - it ideas please?

    If your BlackBerry is still under tension turned off with a black screen, follow the instructions below. The only indication of life may be the flashing red indicator light in the upper corner. Nothing seems to wake and Desktop Manager does not recognize that a device is connected.

    (1) make sure that you have Blackberry Desktop Manager installed.
    http://NA.BlackBerry.com/eng/services/desktop/
    (2) on your PC, go to start > run and copy and paste the following line exactly (i.e. with quotation marks):

    'c:\program files\common research in motion\apploader\loader.exe' /nojvm

    (3) the Application Loader Wizard will appear - click on "next".
    (4) in the ' connection: ' drop-down menu, you should see "USB - PIN: UNKNOWN". Click on the button "next".
    (5) you should see a list of applications ready to be installed for your Blackberry. Press Next and finish, and that you are well on your way to get your Blackberry to life.  Just unplug and let the process finish completely.

    NOTE: If you do not display the list of applications mentioned in step 5 and instead to see the message "the Blackberry Desktop Software has no Blackberry Device Software for the device you have connected to the computer. Contact your wireless service provider or system administrator', then you must download the Blackberry operating system for your support and your device.
    http://www.BlackBerryFAQ.com/index.php/BlackBerry_Operating_System_Downloads
    Just select the appropriate type of carrier and network, select your Blackberry model from the list and download the latest version. Install this download and follow the steps above again and you should be on the right track.

  • HP Laserjet 1018: Printer light blinks 15 times but does not print

    I have 2 printers, my work horse HP laser jet and a Brother Multi printer/scanner/fax etc. Both printers work correctly when connected (usb to LJ1018 connection) or wireless (Brother MFC) to my notebook running windows 7 lite.

    My desktop HP compaq core 2 duo machine is connected to two printers with the help of a brother network cable and a usb cable for the LJ1018 but I decided to connect the brother wireless to my network, because it allowed me to use my netbook without having to plug in a usb or network cable. I also created my office to connect wireless to the brother and it works fine, but now I find that I can not use the LJ1018 that I think only has a usb cable connection. Although the computer says the printer is connected it is flashing the light several times - about 15 but does not print anything. I tried to reinstall the USB driver but this makes no difference. One thought I have is that Windows XP cannot deal with a wireless connection, but also a connection usb, if yes can I have go back to wired connections?

    Hi @petec48,

    Personally, if it is not broken, do not fix.

  • The red light blinks and I can't print.

    I reinstalled, activated and deactivated, changed the ink and still no luck.

    Thank you for the information.  From what you describe, looks like the printer's mistake out there, but don't not giving much information about what is at the origin of the problem.  I found this document on the flashing of the patterns of light for your printer that should help you to find the cause of the problem and fix it.  If the document can help you to work around the problem, you may need to get a new printer.

  • Turned on, the red light flashes twice used to blackBerry Bold 9700 Smartphones

    Hi all

    Last night during the use of my bb bold 9700, it comes went away, came back and then my bbm (messenger) has been removed, so I tried the update of the OS which proved a failure, unplug my bb from my cell phone minutes later, it exploded and the red light blinking twice, charge all night and symptoms persist. can someone help me please.

    Thank you

    Remove the battery and leave it out for about 2mins. Insert the battery and see if works. If this does not work, you can try the update of the new OS but this time with the battery. When the process gets to "Loading Applications" insert the battery and let it go through to the end.

    I hope that you have a previous backup, you won't be able to recover your data

  • Data Push causes phone vibrate and red light flashes

    Hello, I noticed that the data push, in our case to the application of the ECL, causes the phone vibrates if the vibration is turned on and the red light blinks for about 15 minutes or more.  I was wondering if there was a way to prevent this, either on the phone, in the program or in Enterprise Manager.  We wanted to make a push to update on a daily basis, but are now rethinking this because our users cannot understand why their phone acts as she received a new message.

    Thanks for any help, Joe

    The priority header and browser notifications specified on the BlackBerry handheld doesn't apply only to browser attacks.  This does not apply if you push to a custom Java application on the BlackBerry (which is tuned for the push).  It is in this case the application to trigger alerts.

    You can refer to the PushedDataListener class in the sample of the ECL to see how notifications are triggered.

  • Screen blackBerry Smartphones Black, red light flashing

    I was downloading an application when a screen message told me to reboot to continue the installation. I pressed the Off button, but now, despite pressure on the Start button, the phone will not come alive, even if she was recently charged. There is just a black screen and the little red light flashes from time to time.

    Hi HarryTyrrell

    Welcome to the BlackBerry Support Community Forums

    By pressing the button Off is not the correct way to restart our BlackBerry device, please perform a battery pull reboot as this device while is powered on remove waiting battery for a min. and then reinsert it wait until the device take a long restart. See if that helps.

    If this isn't the case, then try to start your machine in Safe Mode and in Safe Mode uninstall your downloaded recently or that you think is responsible for this.
