Why does my tv screen go black every once in a while when i stand up?
My educated guess is that there is a loose electrical component within the set that is loosing contact for a moment due to movement in the room. Keep in mind that even a concrete slab house has some give when people walk around or get out of a chair. Try tapping on the top of the set and see if that causes the screen to go black. If so, it's best to take it in for a repair - which should not be a costly one.
Why does a black box keep showing up on my tv?
When I watch tv ( I have a SONY) I get a black box that comes up on the tv screen. I have to hit the tv menu button or turn the tv off to get it to go away, but it ALWAYS comes back. It happens more often on some channels than others-- like the Food Network and it's so annoying that I can't even watch these channels anymore. Any help would be so appreciated! Thanks!
Why do I randomly black out?
If it is when you have just stood up, you are experiencing a 'head-rush'. It is caused (I think) by a sudden rush of blood to the brain after a long period of inactivity. Otherwise, if not, get it checked out by a GP. Hope this helps Elliot x
Why does my vision turn black and I go extremely dizzy and hot when I stand up? This happens often.
Lightheadedness often occurs when you move quickly from a seated to a standing position. This positional change results in decreased blood flow to the brain. This can create a drop in blood pressure that makes you feel faint. ... It's often caused by problems with the inner ear, brain or heart. I also found this happened a lot when playing music. I got to grade 7 flute and stopped recently because of the amount of lightheadedness I got. I often fainted. Getting up slowly helps. Staring at a screen on a phone while standing can also give you lightheadedness if you suddenly look up and start walking. Slow movements will reduce the lightheadedness a lot. Hope that helps :) ;)
Why will the dashcam screen go black after recording for some time?
I have ever learned about dash cam of this model, it is easy to solve the problem, the phenomenon happens because of the screensaver setting, it can be adjusted according to your personal preference, first of all, click the setting option in the menu, find the screensaver option, then set your screensaver preferences to blank.Actually, the screensaver setting is a kind of power saving mode, and if the screen is on all the time during driving process, it may influence the sight, it is also for security's sake.
The upper half of my TV screen is black or has a colour lining. You can only see the picture on the lower half. What could be the problem? Which type of maintenance is required?
One of the horizontal parallel magnetic plates of your TV's cathode ray tube is not working. It may have been caused due to higher current feed.You need to replace either the electron gun mechanism (if it is available) or the entire cathode ray tube.
Why do we see numbers or codes on the screen while watching TV?
These numbers are a part of the anti-piracy measures taken by channels. Let me tell you how it works :(1) This number you see on your television is generated for every region,using some hashing algorithm.(2) This number is interspersed in the video stream at random places,so that it cant be taken down by using video processing algorithms.So If someone tries to take a video of this stream/show either using a video camera or by using screen recording, this number will go into the recorded video using the media company(the owner) can track down the place of recording, and hopefully catch the people involved in this crime.
My laptop turns on but the screen is black. What do I do to fix it?
Other answers have jumped to a hardware fault. Perhaps not incorrectly, sure. But I'd first make sure we're not dealing with a software issue, or any other "have you tried turning it off and back on again?" sort of things.First, and foremost, does your laptop have a "Display Off" button? I have a Sony Vaio which has one of these. It's a flush bezel button near the clamshell hinge. I have absolutely no fucking clue why it's there. But it is. The only thing I can think of is it's a "privacy" button...for when you can't quite hit the (x) close button on the browser window when your spouse walks in on you ogling (.)'s.Since you didn't post a picture I will assume that you mean the screen is entirely black. No faint glow, no nothing? In other words, it doesn't look even remotely like this [note the blinking cursor]:Have you plugged anything new into your laptop recently? A new USB device? A new external drive? Do you have a docking station? If you have a docking station, does it behave differently if on or off of it?Have you verified that your battery is charged, and that even if not, your power supply is providing proper charging to the battery when it's plugged in? My laptop has a little lightning-bolt LED that indicates the power supply is properly plugged in. Sometimes those stupid connectors can become loose -- or worse, crimped [kids knocking the thing about, etc.] -- so that they don't make a proper connection. I can't tell you how many times I've sat down with my laptop that had been "plugged in" for hours only to hit the power button, see it appear to go through its start-up groans, only to have it fizzle-out and not work shortly after.Do you have a recovery disc for the OS you have installed? What happens if you turn the power on with that in the laptop?Do you have a USB memory stick? If so, there are a bunch of different things to try here Boot and run Linux from a USB flash memory stick, even booting DOS from it.
