Question about Televison & Video

Red pixels I own a LG 42PC3D Plasma tv. When ever there is movement in scenes that are dark or where the background is black, red pixels momentarily mimic the actors movements. It is more prevalent on the antenna input. I have changed the antenna cable to RG6, but still see the same thing.

    I have the same problem with my LG42 inch plasma that is 2 years old. The problem on my TV seems to be intermittent though and sometimes is quite bad while others unnoticeable.

    Hope it does not cost too much...any idea?

This prob shows up often in this set. To solve , remove the 4,784 screws from the rear cover. Plug in and connect the set. Operate until red dots appear. Locate the V_SET-UP control on the Y-SUS board ( the one on the right from the rear ) . VERY CAREFULLY and SLOWLY adjust till dots dissapear and STOP. This adjustment is VERY sesitive and requires only the slightest adjustment with a small insulated screwdiver and a steady hand. BE WARNED ... there are high voltages and high peak pulses on these boards. Not all heat sinks are grounded... some are quite lively. Dont touch anything else, unplug the set and carefully replace the cover. Good Luck..

You will need a professional to service your tv. basically the tech needs to  connect an osciliscope to the y susatain board and adjust the voltages on this board. most plasma tvs will need this done about every seven years because electronic components tend to lose their value over time. this is called electronic drift.

I had the same problem on my Samsung LCD. The Samsung repair guy said the problem was the FFC (flexible flat cable) that connects the mother board to the panel. He replaced all three components (panel, mother board, FFC) just in case.

It sounds like you may have a Y sustain board failure. If you open the set, the large board to your left is the Y sustain. Most of them have part numbers on the board and you can order it from a LG supplier or LG them selves. 1800-243-0000
I hope this helps

Contact your LG dealer to arrange a service call & have the software version updated, an older software may be present in the TV which can give a white screen start up problem

Getting light pixelation on dark scenes.

Sometimes a technician can make adjustments to the y-sus and z-sus boards on the panel. If that doesn't work then its either replace those boards along with the main driver board or replace the panel. Either way this requires a technician to look at the TV.

Red Pixels

First do the basics of checking all the settings in the menus. Call the tech support for your set to make sure that there is nothing that you have missed.

If the set is defective, this can be a processing fault where there is some aliasing. This can occure with interpolation errors or loss of data.
