Satellite P300 - screen empty since turned on, but sometimes works well

HELO,

I have a Toshiba Satellite P300-1F0.
The screen is blank when I turn it on, even the splash screen, and I can't hear the sounds of windows startup.
Although if I turn it on, and besides, it will work after a few tries, sometimes it works the first time, others, I turn on and off like 20 times until he finally started working. When it turns on, it works perfectly.

I tried:
by pressing the power button for 1 min while the charger and the battery
Manually check the RAM.
reinstalling and updating graphics and monitor pilot card.
shaking the lid to check if there is a broken cable
but none of these things worked

I also noticed that the computer works with an external monitor (TV) connected via hdmi.
If I turn on the laptop, the screen is blank, no sound Windows played and after a few minutes I plug the cable hdmi, the Tv shows that windows was, and sounds begin to work from there.

When you are connected to the TV, I try to turn on the screen by pressing (windws key + P) but it does not work.
In the menu screen resolution, windows cannot detect the display, only the TV

Can someone help me? What can cause the problem thr?
A soluction?

Thank you for your time,
Adriano

  • Satellite M50-130: no sound from speakers but helmet works well

    Hello

    I have a laptop Toshiba Satellite with Harmon/Kardon speakers, using the Realtek AC97 Audio sound card. For some reason there is no sound coming out of laptop speakers, but when I connect earphones I get the sound perfectly fine, if clearly is not a volume control number. Device Manager indicates that the sound card works fine.

    I tried the system restore, and it does not work. Can someone help me please?

    Thank you! :)

    What s the name of the laptop?

    Looks a bit like a problem with the speakers for laptop
    The graphics card and the audio driver works very well if the sound is coming through the headphones.

    In this case, the technician should be contacted because everything looks like a hardware problem.

    Good luck

    Hello

    Strange! This problem only occurs when you're on the internet and use the firefox application? What s on IE? Occur also with other programs?

    These strange sounds of relay, and if it appears only with a specific application, so I guess it's a software problem.
    Sorry, but all I can suggest is to remove the firefox and install again or / and recover the device with the Toshiba Recovery CD supplied.

    My iphone 6 s screen has totally blacked out, but siri works.  What is its cause?

    Press the sleep/wake and home buttons and keep them for at least 10 seconds.

    If this is not enough, take a look at these articles Support from Apple:

    If your iPhone, iPad or iPod touch does not respond or does not turn on - Apple Support

    Use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

    As a final step, try recovery mode. Turn off your unit, then plug it to your computer with the hold home button. Hold down Home button until you see the logo on the screen of your iPhone iTunes. After that on your computer, you should see the iTunes window saying that your iPhone needs to be restored to factory settings. Click Restore.

    More info here:https://support.apple.com/en-us/HT201263

    If these steps do not work, contact Apple and ask for help.

  • My laptop screen is blackened or shaded, but to work. Something is darkening up shortly after departure. What should I do?

    My laptop screen is blackened or shaded, but to work. Something is darkening up shortly after departure. What should I do?

    The backlight that run on the screen is burned.  This isn't something that you can fix because it involves disassembly of the computer and parts are not generally available.  It's a hardware problem.  You need to take your computer to a repair store to fix this problem.  If the computer is in power saving mode, that there is no display at all, shines a flashlight on it would reveal a slightly glossy, empty, black screen.

  • I have a Creative cloud photography Plan (CC of Photoshop Lightroom). There a serial number for registration? because I have received no series by mail, but it works well!

    I have a Creative cloud photography Plan (CC of Photoshop Lightroom). There a serial number for registration? Because I have received no series by mail, but it works well! And he never asks me to activate with a serial number. I just pay monthly Plan.

    I ask this question because I have to change the computer and I didn't have trouble disattivate App and put it on the new pc!

    Can I turn off just from the creative cloud by disconnection of the account application, uninstall the application and then install on the new pc?

    The CC has not need any number of series, it is based on an Adobe ID.

    In the case where you are prompted for the serial number then you can refer to.

  • Satellite P300 connected to the WiFi router, but no internet connection

    Help!

    I have a Satellite P300 installed with Windows Live Onecare... and a netgear Rangemax wireless router
    I have no idea as to overcome this problem... I just moved house and it worked just dandy in the old place

    Any suggestions would be greatly appreciated.

    Thank you

    Hello

    If everything worked correctly in your old House, then I guess there is no problem with the laptop but the router is simply not configured property or there is a problem with your ISP (internet service provider).

    Maybe you should get in contact with the ISP and need to check if the connection is ready and available!

  • Satellite A20 - screen begins to turn white

    So I'm having a problem where my pc screen begins to turn white unless pressure is applied on the lower rear of the monitor. As I was typing this message, the screen has managed to stay sane by himself for a while, but then returned, so I think it mya be any hope for her.

    Any help will be useful, thank you advance.

    Hi IBE876,
    What a Pseudo ;-)
    It looks like problems with the lcd screen.
    to me it looks loke a defective cable and / or a bad inverter.
    do not open the cover of the display until you know what you're doing and you have no guarantee on this machine more...
    This inverter is a dangerous thing! It produces a high for the lighttube voltage.
    If it is still warranty on this unit, better consult a servicepartner, there also the spareparts right...
    If you want to do it by yourself... Keep in mind, it can be dangerous!
    Make sure no powersource is connected to your system and battery is taken out.
    Maybe it could be a loose cable...

  • Satellite L70 - no sound from speakers but headphones work well

    Hello

    I have a sound problem with my computer (satellite 70 L)
    I tried everything but nothing to do, no audio output, but plugging the headphones into the audio port reinstall his works well, so I uninstall Conexant, even for its dts but its still doesn't work does not,

    Thank you

    In my view, the symptoms of laptop are clear enough: he does not resemble his driver or system problem because the sound seems to use the headset.

    I think that the internal speakers are defective. It seems strange to me that the two speakers have begun to malfunction at the same time, but this problem may occur.

    But before you contact the authorized Toshiba maintainer to fix, I would recommend you to recover the laptop just to be sure that this problem is not related to the failure of the system/software to 100%.

  • I upgraded to firefox 3.6 recently 11, but firefox11 works well with my windows 7. It became slow and strucks on for 6 seconds for each click.

    11 Firefox hangs frequently for about 6 seconds for each click as switching between tabs, closing tabs, opening new tabs.
    by clicking a link etc,
    3.6.17 worked well, but 11 Firefox is too slow.
    problem is the same with version 4 and 4.01
    can someone please help me to solve my problem

    I'm sorry that you have problems with Firefox doesn't work is not as fast as it should. I'd like to help you here so that you manage Firefox running at great speed.

    Firefox, try to start Firefox in Safe Mode. It temporarily disables your extensions, customizations, etc. so that we can see if they slow down Firefox. If Firefox works fine in Safe Mode, then it is probably a problem with the add-on. Restart Firefox in normal mode, and then type "subject: addons" (without the quotes) in the address bar. Disable your extensions, restart Firefox between each one, until you find the troublemaker. Once you do, you can disable this add-on.

    I also see you have advise McAfee Site. I would recommend disabling that, as it is known to cause leaks of massive memory than Firefox slow down

    If Safe Mode does not work, you can also try updating your graphics card driver. Update your graphics drivers to use hardware acceleration and WebGL reading can show you how to do this.

    Hello
    I have a toshiba A100, Go 7600 Gpu, just bought there is two weeks and im very pleased with the quality and performance far :), just noticed one thing today, the room was turned off and the laptop turns off with the screen in open position, I leave it open normally when at home, I noticed that the screen flashes as fixed every 1 min in what appears to be an interval of time with or without AC connected, not a flash very bright but not easy to notice, but I'm sure the flash, so my question is should I worry about this? Thanks in advance :)

    Hello

    What do you mean with the screen? The LCD internal? Maybe you didn t stop the machine itself.

    I also suggest you update your bios and your drivers, maybe it s just a software related issue...
