You have main board issues, there is a 3.2 volt regulator on your TV that gives issues and will make the set turn on at random times, replace the main board and it should fix it, or you can order the part for under a buck from China and replace it yourself if you have soldering skills

Use your remote to reconfigure the picture. There may be a picture button on the remote that will switch the picture from 4:3, 16:9, Standard, Stretch, and so forth.

switch on the dvd player so it's playing, then do a new master tune. press the dtt/tv button so you are watching the internal freeview system, then press menu, then go to installation, and re-install all channels. the tv will then detect your dvd player in the intial set up/tune mode.

hope this helps..

According to what i could find, there is no way to actually SOLVE the problem, this is what i did find; The plasma display panel is lighting the phosphors by the discharge of internal radiation. Depending on the screen contents, in rare cases this may cause vertical stripes to appear because of failure to light. Please note that this is not a malfunction.

unplug. Press and hold power button 10-15 sec's then repower see if ok. Most tv's will go into standby if there is no signal detected.
