I accidentally killed power to the TV from a switch in the van instead of turning it off A TV, like a lamp, doesn't care whether it is turned off by unplugging it from the AC outlet or by whatever switch was provided by the manufacturer. The lamp also would not care if it were connected to AC or DC, as long as the voltage was within design parameters. A DC operated TV WOULD care if somebody were to try to connect it to AC.
Twice after smacking it the picture went back to normal Implies that set has a bad or intermittent connection - Dirty A/V or Setup switch (if is a mechanical type), cracked PC Board, foreign metallic material connecting two points that aren't supposed to be connected, or bad solder connection(s) for example.
The general public sees a rotary type adjustment (G2, on the Flyback) and their first instinct is "Let's turn this to see what it does" (should we mark it first so that we can return it to as close as possible to where we found it? ... Naw, you don't think we can remember such a simple little thing) could, in theory, in and of itself, be the cause of the blue/white screen with retrace lines.
