Shadows/flickering on one side then screen will have no picture but has a sound

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.

You now have a 55" parts unit !!! A replacement 55" panel will most llikely cost as much as a new set !

I would to see a picture of what it looks like. What you are describing sounds like a faulty LCD panel tab. Samsung LCD panels are known for this problem.

if rebooting the monitor would do no good, try to get a spare monitor cable if the same flickering issue took effect. If it is so, then call your pc provider to repair your monitor..

Try doing system restore..check if that works else contacst gateway..your laptop's lcd needs to be replaced at 800-846-2301 for further help contact me again thanks

sure sounds like loose solder joints, look for them in the deflection circuit, just find the hard plastic encapsulated body with the thick red wire sticking out of it thats where usually the loose solder joints develop.

try bending the connectores slightly up and down and check if the problem will be fixed, if that seems to solve the problem purchase anothe AV cord for your PS2 also try testing your PS2 on another tv and then let's see if it will solve the problem

yes sounds like a convegence issue.

I have the same problem and was told by a technician that I need to replace the light engine. Probably around $ 700.00.

shadows at the bottom of the screen sound like moisture that was "wicked up" between the screen layers and dryed out leaving a stain. DO NOT get these screens wet, use nothing but a damp soft cloth; just a few drops of water running down the screen can cause a fairly large stain. Some people have suggested that they may be professionally cleaned, but the risk of damage is too great on the user level.
