This comes up so often, that I thought it deserved a sticky. Does it?
Here's the what how on tate-ing your TV
WHAT IT MEANS-
Turning your television on it's side so the home ports match the arcade games with their vertical oriented monitors. The home port needs to have the option in the software. YOKO means horizontal monitor, TATE means vertical. Apparently, most Japanese releases have a tate option, lot's of US and European releases don't. Games play great in their original formats, so tate-ing is always prefered over black bars on the sides of the screen or a diminished play area.
Parts of the television aparatus that aren't held secure or aren't designed to hold their own weight could physically break. Apparently, most TV's are tough. Some are wimpy. If the TV's case does not have a flat and ballanced surface to stand on, it will tip over or roll off the table. Perhaps some foreign debris or dust buildup inside the TV could shake or move around and break something.
SIDE EFFECTS, SKEWED COLORS, and DEGAUSSING
The only negative side-effect of tate-ing your television (besides rare but possible internal damage) is the phenomenon of a 'green screen' or skewed colors. This is a physical manefestation of the earths magnetic field on the CRT (Cathode Ray Tube- the screen). In order for a color TV to display the proper colors, the CRT needs to be 'degaused' or demagnetized. Inside your TV, around the perimeter of the screen, there is a thick cable called a 'Degaussing coil". It demagnetizes the screen the moment you turn on the TV, before the picture comes up. The thing is, the coil gets immediately hot and would go ahead and light itself on fire if it weren't connected to a 'thermistor', which is a component that slowly turns of the voltage as it heats up- so it goes like this= Turn on the TV> Degaussing Coil does it's thing> Thermistor turns it off, and keeps it off until it's completely cooled down AND the TV is turned on another time> Screen lights up properly.
The thing is, the TV gets degaussed RELATIVE to it's positioning in the earths magnetic field, so any changing of the television's position will have an effect on the screen. Sometimes, just changing a TV's lateral direction will make it go green. Also, OTHER magnetic fields exist, too. A loudspeaker or other stong magnetic source set next to a TV will screw it up. Also, the degaussing, or demagnefication, must be greater than whatever magnetized the TV in the first place. For example, an older TV that's been sitting in the same position for a long time may become more 'fixed' to that position in the earth magnetic field than it's own degaussing coil can undo. In that case, you simply need a stronger coil. They can be bought. You can also use a bulk tape cassette eraser. You can also just use a magnet stronger than whatever did the damage to 'wave the colors away' like a magic wand. You can also rip a coil from an old TV and just plug it in and go to it (Just make sure you pull the plug before it lights on fire).
So, to sum it up....
1. The 'green screen' is temporary, under ANY curcumstances.
2. Wait for your thermistor and coil to cool down (it seems to take anywhere from 1 to 30 minutes for the degauss circuit to reset), then turn ON the TV *in the exact position in which you'd like to watch it*, and it will degauss in the few seconds before the picture comes up. Repeat the process when you want to put your mothers TV back down.
3. If the colors are still askew, you've simply got to find a better way to demagnetize the CRT. Also consider that your degaussing coil might not be working at all.
pre-requisite= Will it break? Will it balance?
3. turn on
3 1/2. if it still looks green, find a way to degauss.
Is that everything? It's the technical stuff that nobody ever seems to know (I've just learned it from the internet myself). Any corrections? A little too long winded?
