Solve : Brightness issues after bootup? |
| Answer» <html><body><p>Hi, not sure if this is correct section, but here <a href="https://interviewquestions.tuteehub.com/tag/goes-1732621" style="font-weight:bold;" target="_blank" title="Click to know more about GOES">GOES</a>.<br/><br/>I have a new pc (maybe 2 months old)<br/><br/>This morning i booted the pc up. All went fine, then i saw desktop bootup for about 2 seconds before the screen went blank. I rebooted a few times. Each time i see the desktop for a second or so before it goes black.<br/>One thing i noticed after a while. The screen doesn`t actually go black, but in-fact, very very Dark. If i focus really hard i can just about make out my desktop in the background. Not enough to read anything, or control my cursor, but i can definatley make out icons, also when i right click my mouse i can see a faint "square" where the option window will have opened from right clicking my mouse.<br/><br/>I`m presuming its a graphics issue, but i`m not certain. Any ideas?1) What is new or different since the last time everything worked properly (ie, new hw, new sw, virus, error, etc)?<br/><br/>2) What happens when you boot to safe mode?

You have in fact described the process for checking for this. If you shine a strong lamp or a flashlight on the screen and you can see the desktop then I would very strongly suspect this. If you can connect <a href="https://interviewquestions.tuteehub.com/tag/another-876628" style="font-weight:bold;" target="_blank" title="Click to know more about ANOTHER">ANOTHER</a> monitor and it works then that would be proof.<br/>Ok. Allan. <br/><br/>Nothing at all is new. I shut it down last night after browsing the web "bbc sport" to be exact.<br/><br/>I`ve tried to boot into bios and safe mode, each time after 1 second or so the screen goes Dark.<br/><br/><br/>Salmon. Yes, i too am beginning to think it`s a monitor issue. If i turn my monitor off and on, each time i will see my desktop for a second before it goes dark.<br/><br/>I`ll grab a monitor from somewhere and plug it in to see. If it is a case of a dodgy backlight, is that a new monitor? or is it repairable?<br/><br/><a href="https://interviewquestions.tuteehub.com/tag/thanks-665909" style="font-weight:bold;" target="_blank" title="Click to know more about THANKS">THANKS</a> for the speedy responses.Yes, if it happens in safe mode I completely agree with Salmon Trout Quote from: gazman on January 04, 2013, 08:30:31 AM<blockquote>If it is a case of a dodgy backlight, is that a new monitor? or is it repairable?</blockquote> <br/>Monitor backlights can be replaced, but if the monitor is old and/or small screen size then the cost can exceed the value of the monitor and even approach pr equal the cost of a new one. Especially if you lack the skill to replace it yourself and would need to take it to a repair shop. You must do some research.<br/><br/><br/>You should be aware that the problem may not be the actual lamp but possibly associated electronic circuitry, and without proper test equipment and expertise you could easily <a href="https://interviewquestions.tuteehub.com/tag/buy-391430" style="font-weight:bold;" target="_blank" title="Click to know more about BUY">BUY</a> the wrong things and waste money that could be put towards a new monitor or a working used one. LCD monitors have got a lot cheaper recently.<br/></body></html> | |
