Did you just buy the tv new? If so either return it to the store or get it fixed under manufacturer warranty. This could be a sign of a definite problem. Did you try changing inputs at all? Does it happen on every input? are you using hdmi?If you need help contacting the manufacturer please let me know what country you are in and bought the tv in. Once I have more information I can give you more definitive answers. If you need further assistance please let me know.
Thank you,
Lee

This is usually a bad semiconductor, and what to look for is a shortcircuited Mosfet SSH25N40A (QU4) , also in the Gate of this Fet there will be a burnt SMD Resistor RCU20.to replace, value is available ONLY in a service manual.
You MUST obtain a service manual... I have been unable to locate one on the 'net, so you may have to approach LG direct and obtain one, it is impossible without one...
Possible links to service manual below, download and check it's the exact model? http://www.fixdevice.com/smanuals/file/38667.html
Below is a training manual, so you can get to grips with what is required. http://www.scribd.com/doc/7580885/LG-TV-Plasma-Training-Manual

LG 50PG20 Plasma,, nothing shows on screen its all black


This model was known for issues with the Y-sustain, Y-drives, and the Z-sustain boards. These boards help process the picture image to the screen.

When one or more of these boards fail, the screen stays black, and you only have audio & on/off.

You could call LG and try to get your TV repaired at a discount if you can convince LG to honor this known issue.

Another issue could be the actual panel has gone bad. The plasma panel in your TV has a two warranty and LG would fix that for free. Well…it would be free as long as it’s not past two years of your date of purchase.

What zip code are you in?

Pink color horizontal lines comes on and off


That issue is with one or more of the board that drive the plasma screen. If you have a warranty, you will want to call LG for a free repair.

Sorry, but to trouble shoot that issue would require some TV tools and knowledge of electronics. There are several boards involved with processing the picture image to the plasma screen.
I hope this information has helped you.
Good Luck.

LG plasma tv made loud popping noise


The plasma gas tubes may be damaged or the gas couldve leak out. remember plasma have to remain upright at all times even when transporting them, if they are not you should just set it up straight for about 3-4 hours before turning it on.

I have just roken the LG 50inch plasma screen. Can this e repaired


If the plasma panel itself is physically broken, it can not be repaired, only replaced. This replacement panel will not be cheap. Often times the cost of the panel can meet or exceed the cost of a replacement TV. If you can post the model number, I'll try to get you the panel replacemetn part number and cost.
