My LG 32 inch HD lcd tv which I bought last April 2010 also encountered the same problem. While we were watching a movie last week, the lower half of the monitor became distorted 'tas nagkaroon ng lines with different colors. I called their hotline number and the operator said they could send a technician the following day which was a Monday. When they arrived, they looked at the unit and concluded that the LCD module is busted. They said they'll come back and magrrequest sila nung parts na sira. I asked him how much ung module kung walang warranty and he said mga almost 27k. Mas mahal pa sa actual price nung binili kong unit. Then on a Wednesday, I got a call from LG again saying pupunta sila sa bahay. I guess he is one of the Senior technician and chineck kung module talaga ang kelangan palitan. Nung maconclude nya na tama yung first diagnosis nung technician nya, he said babalik sya pag ok na yung request for a new module. Then this morning, he called again saying if it's ok kung ngayon na nya gagawin yung lcd 'coz dala na nya yung replacement module. After 20minutes, my tv is as good as new literally coz bago na talaga yung LCD module. 
this had happened to me last night when I was playing my PS3. I had called their service center earlier to report the issue and they said that they will be coming tomorrow or friday. hopefully they can fix my tv asap.
