Try a power drain and if this doesn't work, it appears the power supply is defective or is not connected to the mainboard. If the connection was poor, simply moving it may have dislodged it and service would be required to reconnect it. Try the power drain first:
1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board. 3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.
Hope this works for you.

SOURCE: hi please help me to
I am sorry to hear regarding the trouble.
Image problems on Plasma TVs are usually a result of a failure of fault in the screen buffer boards. There are several buffer boards and each controls a section of the screen: either a column so many pixels wide or a row so many pixels wide. When the buffers start to fail, it is common to see lines either from top to bottom, or from side to side or just portions of a line going halfway across.
You are going to have to call in a pro to check this out. There is no way that someone over the internet can correctly diagnose the TV without being there in person and then it would likely take hours of diagnosis to narrow down the bad part.
It's probably your buffer boards.
If you have electronics repair experience and would like to conduct the repair, revert and i would be able to add few more inputs.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
