Question about LG 47LG50 47 in. LCD HDTV
IT TURN'S ON BY ITSELF MENU SCREEN POP'S IN AND OUT REMOTE CONTROL WONT WORK MANUAL CONTROL BUTTONS WONT WORK. TV IS 1YEAR OLD
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. =)

The buttons on the front of the set fail, (like mine did) even if they never get used. Probably the 'DOWN Volume' in your case is stuck closed. Try pecking on it first. My remote stopped working but so did the manual buttons too. While poking around on stuff I swished my finger across the buttons and it all started working so I knew I was on to something. I never figured out which one was the culprit as it continued to cause problems and was replaced as a complete unit under warranty.
The other quick check/fix is to remove the trim plate around the button plate (pop out stays like the speaker covers) , then remove the button assembly (3 screws plus pop out stays like the speaker covers) then unplug the multi colored lead from the button circuit board. This puts the Remote back in control and it will work just fine like this, minus manual control of course.
