SOURCE: Have 42 inch LG flat screen...for about 3 years...

Take the back off with no power connected..You should have 2 invertor pcbs..one on the left and one on the right..well the side of the picture you cant see is the same side of the faulty invertor..replace this and this should solve the problem.it is the cheapest option..if not..im afraid is is a new LCD screen unless you are prepared to take it appart and replace backlight bulbs :)

SOURCE: My LG 42PC3DC has ghosting

The ghosting is a sign of slight image retention and the reddish hue is over diffusion. This can normally be fixed by a voltage adjustment on the power supply.
Unplug the set and take the back off
Plug the set back in and turn the set on
With a digital voltage meter find the test point on the power supply that says VS. If you cannot find it, you can still measure it at the connector. It will say VS in a few different places.
Compare that voltage with the voltage that is on the sticker that is on the panel. If it does not match
Take a small screw driver and find the pod that says vs adjust and adjust the voltage to what the sticker says. If it already matches, then raise or lower it about 10 volts or until the picture starts clearing up. If it does not clear up either direction, then you will need to replace your logic board, which is the small board near the middle of the panel. Worst case scenario is that your panel if faulty, which would not be cost effective to replace.

Half panel of my LCD tv has slow refresh rate. As a result it has ghosting effects (motion blur), I have replaced t-con board and play around the bond tape but it remains. My tv model is LG 65LM6200.


Seems like T'Con board fault. If you wish to get some details; check the site linked here. Pull up older posts.

WD 73835 has ghosting images during dark or red scenes


Make sure your contrast isn't set too high. Most ghosting is caused by either contrast, brightness or tint issues. Try adjusting these settings. Also check if there is a Dynamic contrast setting for your TV as well as this can cause ghosting also.

My Sony KDL-32M3000 has ghost (dark red) display with slow motion picture. What could be the cause and how can it be repaired. Thanks


Thats usually caused by bad flex tab bonds on the LCD panel itself. If you search for flex tab issues vidoes it will show how the pisture can get slow motion in areass as well as double images in that area.

Sony Bravia KDL52W4100 52 inch TV that is ghosting


This is a good picture and the tapping confirms some thing I have seen, this model is involved in a recall of sorts--the most common issue with it is around the T-Con board.

It can be bad connections on it or where it connects to the screen unit, it can also be inside the display panel (screen unit) where it cannot be got at

If it reacts to tapping any good shop will find if bad or loose connection outside of the display panel--if inside there is not a way to get in there, entire panel would in that case have to be replaced which usually means its cheaper to buy a new set.

have a expert or a shop look to see if outside the display panel or not.

LG 55LV5500 video problem. VERY slow response time - looks like the tv is in slow motion w/ the images trailing behind.


The main digital processor board should be suspected. Contact any experienced service technician.

The image is blurry (ghosting) and dark.


the tab bonds on the lcd panel where they attach to the Drive circuits above the TCON samsung is famous for bad flex tab bonds. Does the screen appear llike its in slow motion and double immages in that half of the screen as well as appear to have dark bands aross the screen? If so its probably the flex tab bonds.
