If it's under warranty have it return to the supplier for replacement. It's hard to diagnose the problem without opening your TV. It could be the vertical IC that is usually a problem in most CRT. It's really hard to tell without scanning the board. Best thing is to bring it to the tech shop near you

After 10 to 20 mins left half of screen goes to white vert lines


Sounds like power supply regulator board fault. Check all the electrolytic capacitors for any leaked or bulged one. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Do asearch by type in the brand name of your device at its search box.

It will be best to replace the power supply regulator board as card basis.

Lg plasma DT50py10. When turning on bottom half of screen is snowy and has lots of white lines for approx 20 min then it goes away. Top half of screen is normal


sounds like your bottom buffer board is on its way out .
Will also need to check the y sus board as this some times causes the buffers boards to fail.

I have a LG Plasma Flat screen TV. I purchased it


With seeing the picture it will be hard fro me to tell what..I am going to guess according to the information you've provided.
It could a buffer or a signal board(s). This TV is only 4 Months old I would call LG and file a warranty claim. LG (800) 243-0000

Best of luck

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.
