Sony KP-57HW40 Picture Issue

Archived from groups: alt.tv.tech.hdtv (More info?)

I have run into an issue with my current TV. When watching dark shows or
even just having it for example on a video input with no signal, the black /
dark is very bright. Somewhat blue with wavy lines in it. No adjustment
seems to help.
Here is an example though nowhere near as bright as it appears in the pics.
Also the focus is actually fine, but since I took the pics in the dark, I
lost all focus.

What could this be? Luckily I have an extended service on it, but am curious
what would cause this.


Thanks

You were right. Bad CRT's. The part numbers have also changed. New ones are
on order and will be installed shortly.
