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.

My Hp pavillion dv4 notebook pc's screen is flickering quite badly. It happens every few seconds and everything seems to jump up and down once and go back to normal. Tapping or hitting screen or any part...


Flickering is a back light issue, jumping around would be caused by the screens reaction to a bad inverter and so would the backlight as well. So flickering backlight and jumping would be a inverter issue causing both problems so I would replace them both.

Thanks if you like my adivice please rate it with the thumbs and leave feedback!

May lcd monitor is flickering


The filter capacitors in the power supply are going bad. This leads to more ripple in the voltage which is why you see the screen flicker. Sometimes the transformers that drive the lights go bad themselves, but generally when that happens you won't have a backlight. Replace the capacitors with the exact same ratings, except you could go up a bit in voltage, and make sure the temperature rating is 105 C or higher. This will stop the flickering.

Ibm thinkpad t43 backlight inverter issue


Did you say the the video output flickers on and off when you connect an external monitor to the video output. If the inverter is faulty this would not affect the video output and the external monitor would not flicker but if the external monitor flickers it would point to a video card problem.

Hp Laptop screen flicker


I am sure that the issue is related to the cable that connects to the LCD Display or the LCD Backlight.
There should be some connection shortage because of which the LCD flickers few times as stated by dan231.
I Recommend you to get the Notebook examined as soon as possible before something really goes wrong...
