I have a Toshiba 57H82 rear projection tv that has been intermittently
flickering too much red. For instance, on a black background it will take
on a reddish tinge then back to normal then reddish again, with no apparent
pattern. Its also not consistent--sometimes it does it and sometimes it
doesn't.

If it was something simple or something others have encountered I might have
a go but most likely I'll have a service guy come in and have a look. So
the point of my asking is two-fold--possible fix it myself, or Know enough
so that when the guy gets here we don't get hosed. Any suggestions or
information is greatly appreciated!

Thanks!
