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

First off I did not see make or model. When plasmas die you have failure in either the power supply of the sustain boards. Do you have any voltage readings from va or vs ?

If it goes all the way from top to bottom, you have a bad panel. much to expensive to repair

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.

Just cut the 2 wires to the switch and cut he insulation back and twist them together with a wire nut......use a switchable power bar to turn it on and off......I did this to a Realistic amplifier and it works fine...........

i don;t know. please put it back, hooked up the same way to see if the tv is the problem. if tv is ok, it seems the cable or
connectors may be loose or connected wrong. if single cable, dollar stores sometimes have new long tv cables you could run from original supply to new position to help you locate problem wire or connector.

Your Hitachi remote controls are not functionally interchangeable. Win some, lose some.
