Display flickering


It is not flickering. It is horizontal rolling. Picture rolls horizontally at a very high speed, and you see it to be flicker. Total loss or horizontal synchronization signal is the fault, and it is related to its chroma processor IC. It is very skilled work to troubleshoot this section, and user can't do this with ease. It is risky too. Contact any service technician. If you wish to get more details, check the site linked below. It has over 2400 posts now, and all are related to service help to different brand TVs.

You can also do a search by the brand name and model number to your device under concern; by type in the brand name and model number to its search box, located at the top right of the display window.http://electronicshelponline.blogspot.com/

Toshiba Satellite M300 screen problem


Hi, I can't guaranty this will help the problem, but for a quick try I say its worth it. On the Desktop, right click to open Personalize, select Display Settings; by adjusting the resolution it helps with the "Flicker effect" aswell, by selecting different settings, you can "view" the best Monitor Display. "If the solution helped, rating it is appreciated, thanks."

Display flickers on boot. then goes black


Before making any decision on whether it's a hardware failure, please try and boot from a CD or DVD (recovery disc). If it does successfully boot from an external disc - and there is no flickering problem, then the hardware parts are okay. In that case, please go to this link: http://lifehacker.com/5413223/how-to-fix-your-relatives-terrible-computer?skyline=true&s=x for more information on what to do when you can't enter into your operating system and how to fix malwares that might be causing the flickering. If you find my ideas satisfactory, please do rate me. Thanks
