I am guessing that you have a cable box ?
You may have accidentally changed the input setting on your TV.
Press input button on the TV Remote Control.
Take note of what the setting is now, in case you have to go back to it. If changing the input does not get your picture back, make sure that you return it to its original setting.

SOURCE: my 50PX5D plasma LG looks like it works but its as

This is also known as "Tiger Striping". Your set is running way too hot. This can also be caused by storage of the unit in a garage or other place that does not have air conditioning. Heat has destroyed the seal around the plasma screen causing it to melt and leak down behind the glass or allowed the space between the glass to become contaminated. This is not fixable. By a new TV.

SOURCE: CANT CONTROL TV

I am currently experiencing this exact same problem with my 47LG50. Since the original thread was posted more than three months ago, I imagine the original poster has had his/her issue resolved, but I can still relay what LG told me to try when I called them. Did it work for me? No. I have to call The Geek Squad with Best Buy (as the TV is no longer under manufacturer's warranty, but thankfully, we bought the extended warranty with BB), but it could work for some, according to the representative I spoke with.

Try taking the batteries out of the remote, and see if this resolves the issue alone. If not, try unplugging the TV entirely and holding the power button down (it's just under the power light, carefully hidden, and shaped like a smile) for at least 40 seconds. After that, plug the TV back in and power it up to see if it has resolved the issue with the flashing menus. Even if it seems to have done, you might want to leave it on and keep an eye on the screen for a while. I had mine abate for a little bit, but then it went right back to flashing menus. The issue of it powering on by itself will be pretty easy to notice if it is still doing it.

I hope this helps someone, although it didn't work for me. =)
