My flat panel is flickering in the right side when it's just turned on


You may very well have a defective LCD panel Henrik. Samsungs are know to have premature LCD panel tab failures. There are several ways to verify this. I would wait to after the set stops acting up and I would spray the upper right side of the screen with "freeze" spray. If the flickering comes back, you have a faulty LCD panel tab. The only true fix is to replace the panel, big $$$$. There are several youtube videos showing you how to patch the problem.

47lh90 blinking red light and flickering


the regulator for the Inverter supply would be the first thing i would suspect if the voltage drops then picks up again. Then I would also check the transformers on the Inverter that are in line with the area of the screen that flickers.

Upper sise of screen flickering problem


Technology b> A laptop's display assembly consists of an LCD panel, an inverter board and a backlight lamp. The inverter board supplies power to the lamp which lights up the LCD screen as it generates images. Light from the lamp is then uniformly distributed over the panel to create images. b> Cause b> Flickering is commonly caused by a damaged or malfunctioning inverter. Because a faulty inverter is not able to supply adequate power to the backlight lamp, the screen goes dim each time the backlight loses power. In some cases, flickering may also be caused by a faulty connection between the inverter and backlight lamp. Diagnosis b> Resolving a laptop screen's flickering problem entails correctly diagnosing the problem and replacing the faulty component. You may diagnose the problem by hooking up the laptop to an external display unit, such as a projector. If the external display has the same display problem as the laptop's LCD screen, it is indicative of a motherboard or video card problem. If the external unit displays bright, crisp images, the problem is probably caused by the backlight or inverter. b> Solution b> You may repair a laptop screen's flickering problem by replacing the inverter board or backlight. Order parts from a trusted supplier and replace the component by referring to your product documentation.

Acer aspire 8935g flickering screen on startup..even i see flickering when i go in bios setup...dos mode is flickering... kindly help... Thanks.


This is not a software problem. This is an hardware one. You have to replace the LCD inverter or to repair the existing one. The most common problem in the inverters is the age of capacitors. Im most of the cases if you replace the capacitors the problem is solved. This is working for any kind of LCD monitors and LCD television set. If you are a handy man you can fix it yourself by consulting the internet to see how it looks the inverter and where can be localized, how it looks a capacitor and where you can buy it, etc. If not a handyman try to ask a tehnician for help... Good luck!
