Hello

Either there are capacitors in the power supply failing or a chip is failing. Iany case you'll need to take it to a local service person or send it to a company like mine.

Picture with distorted,flickering, darkened area on rt. side of screen . Up to half of the screen sometimes. Sometimes looks like vertical hold is rolling some. Then will be clear with no or tiny amount...


There are several possibilities here.

To be able to help better we'd need to know the model number.

The most likely suspects are the T-CON board, one of the two backlight inverters and the display itself.

Of those only the last one is usually not curable.

Here's an example of a popular set of inverters that , when one goes bad you can get one half of the screen very dark:

On the other hand, if you have vertical shadows and some flickering that's probably NOT going to be a backlight inverter.

Flickering would be caused by either the T-CON or the panel.

Since a bad panel is mostly NOT curable you may want to check the price of a replacement T-CON and decide if it is worth taking a shot with one before you displace the TV.

Again, the thing to start with is the model.

Hope this helps.

Laptop monitor bad color and flickers continuely, but when attached to external monitor, works fine


I'm going to take an educated guess here, because it sounds like the monitor's interface controller is bad. I forgot the name of the thing, but it's a small circuit board that's normally located at the bottom of the panel frame, between the flat ribbon cables and the round hinge cables.

Samsung ln40b550k1f screen flickers on and off


When the screen flickers on and off it usually comes from the power supply or backlight inverter being bad. For your TV, the backlight inverter and power supply unit are combined. As you can see in the picture attached it's the white part on the right side that has gone bad. You will need to replace that board. LN40B550K1F Samsung LCD TV Repair Guide

Monitor flickers with lines across screen


screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

FLICKERING BACK LIGHT


Sounds like you have an LCD tv with backlight problems. Check power board for domed capacitors and replace them. next check connections on the inverter boards. they are on the sides or just one side. Becareful there is high voltage output from these boards. If the cable from inverter board is not good to the screen you can get a strobing. the inverter boards may need replaced. or cales to screen may be bad. The panel also could be bad.

My Dell Latitude C400 PC Notebook screen flickers very fast, any ideas? thanks


It can depend on what kind of flickering you are seeing. A very very fast one, that shows more obvious if you look to the side of your screen (instead of directly at it as normal), means your screens 'refresh rate' is most likely wrong.
That's the most likely problem you have, as the inverter will usualy only make a screen flash, not flicker, though they don't usually flash too much before the bulb or inverter can't take the strain and breaks properly.
Sometimes a screens circuit can go slightly faulty (very rare) and cause a slight change in its refresh cycle, and that can cause a high speed flickering too, usually accompanied with a very slight blurring of any images.
The standard setting for a C400 is 1024 x 768 resolution at 60 Hertz, so check your display properties to see that's not been accidentally changed.

HP L1720 flickering!


this is common, the display is bad.
all displays, fail. all do. no reason to get angry,
a broken display is worth nearly zero value $0
so how much money will you spend on worthless.?
you can get a new display at Walmart for $65, ,
lines are usually very serious. and is not ever the DC-DC inverter
a bad inverter (< it's power supply) is for the back ground lamps. not data side. the data side is failing and is common, if you twist the screen
it gets worse. ? bingo. data driver connections bad , screen.
IN most cases the part that is bad (screen), costs $100 new. or 50 used
why go there/
?
