Yes, maybe all of them.

I can't belevie this... now it's woking good, no more waves on screen
and no more fuzzy music on Unknown Reality...
I'm sure i'm not dreaming cause i have the mp3 of the music and videos
of the screen on my phone :)
I did this:
- I got a phonola 8280, so i get the video board and put in my
I don't know a lot about electronics, but maybe the PSU in your 8280 is
going bad, and putting it in the other machine charged the capacitors on
the board just enough to work again with the bad PSU for a while. If
that's the case, the wavyness should return.
Just an idea :)

Hi all,
the video of my 8280 has become a little bit wavy.
I've found out that is a problem of the analog board, because swapping
it with another one the problem disappear.
How can i check what i wrong with the boad?
Thank you wery much.
