Question about Hitachi 42HDT51 42 in. Plasma SLC1551AW
This isn't a setting problem, you have an imperfect contact in the mainboard - a soldering has cracked and makes contact only after the tv heats up and the part that should be soldered dilates. Since it has happened after you have worked with the cables then you must take the back cover off and, using a magnifying glass, look at every single soldering point around the image processor and the AV inputs - everyone that looks iffy, redo it.

Thanks for using FixYa. These kinds of issues in plasmas usually occur after 3-4years.A plasma TV is a very hard working device. From what you have described it seems to be an issue with the power supply board which is the board where all the power cords plugs into.It is working harder than any TV that has been built before, and as a result it produces a lot of heat. 75% of technical problems in plasma TV's are caused by overheating problems. You’ll need to check the power supply board first for any swollen/bulged capacitors. As power supply board is the hardest working board in a plasma TV, it develops voltage to supply all components, high current + high voltage. All this is only recommended if you have electrical expertise & know how to solder/re-solder components as these units contain high voltages even when switched off. Please do accept the solution if the issue is resolved or post a comment for further assistance.
