SOURCE: SCREEN FOR LG 42PX5D 42 in.

I have dealt with Lg in the past regarding screens and they are unable to sell them as a spare as they are so expensive, they are only used in production and a complete new HD TV is cheaper to buy than a screen. for example LG37LP1D £900.00, a replacement screen £1500.00

SOURCE: Black box appears in middle of screen

go into the menu and look at the closed caption option----if TEXT is highlighted--this is your problem---select CC! or if it has it OFF.The TEXT will only appear on certain channels and it most likely was activated by someone changing the closed caption options. If this has been helpful give me a vote to let me know.

SOURCE: LG RU-42PX11 42 plasma TV has black bar

it seems to be a bad connection somewhere but I disconnected the ribbon cable and got a verticle line of snow instead of a blank line. the line is about 34 mm wide and starts 285 mm from the left edge starts on the Blue and goes to the Red pixels. so if they are 1mm wide that would be 34 bands of color.

I would sure like to figure out the solution to this one or I got a TV I need to throw away cause the o'lady is gonna bust my balls if I can't fix this!

SOURCE: I have poor color and when the screen is dark many

This is a common fault on all LG sets with few people offering any solutions. I can offer a solution that could remove 95% if not 100% of the dots.
Remove the back of the set, there are about 40 screws. On the left hand side on a circuit board you will see 3 or 4 blue plastic boxes with yellow screw adjusters in them. The only 2 you are interested in are VR3 "setup" and VR2 "setdn". Mark the location with a marker pen so that you know where the factory settings were. Then turn VR3 fully clockwise. If this does not get rid completely do the same with VR2. This worked for me today, I was about to throw the TV away but I now have a 95% improved screen, sharper and more vibrant picture and saved hundreds. Hope it works.

I have dots running across the screen


If the dots are red and green, that's normal. Just enjoy your hd picture. actually, I think the dots make it look clearer. The only time I can really see them is when the screen is black.

Lg 42'' plasma 720p no picture


This is not good. Was your tv unplugged or just power button off when you left for vacation. PlasmaTvs are highly susceptible to damage from power surges caused by lighting. Leave unplugged for at least five minutes then plug back in and see if this helps.

Plasma tv has little red dots in the black


This problem (known as sparkles) can be cured by adjusting the ramp control on the Y-Sustain board. If this does not cure the dots then there is a software remedy for the control board which an LG repair centre could fix. Failing that a replacement board is required. The orbitor & whitewash are like screen savers to help to prevent a screen burn from a permanently displayed image.

Problem with LG 42 inch plasma


If you notice these dots when you use Video or HDMI inputs, then you need to do something to get rid of them.

Open the back cover, try to reduce the Vs voltage 5-10V below its spec value. Vs is from Power Supply Board and its spec value was printed on the back of PDP panel. If your tv is under warranty, just drop it to the warranty depot shop.
