plasma tv will go out, freeze up, won't have a screen but will turn on (like mine right now) during solar storms. plasma screens are tubes of ionized gas.....solar storms (earth directed) is plasma discharge from the Sun...ionized gas. You cannot see it but you will know when it is around because it will cancel out your plasma (ionized gas) tv. its true...our tv has been doing this for about a year. solar activity has increased. and you are correct, all of our other tvs work fine.
