Television and Home Theater

I replaced the "G" board and now it clicks and then flashes 3 time so I know the "G" board is working.. all I hear is a clicking in the back...

 anyone with ideas??

thanks

I have a Mitsubishi 62525 DLp TV purchased in sept 2004. I have noticed in the past 2months or so what I thought were smudge marks on the screen. As i cleaned the outer screen as per manu. instructions the smudges did not disappear. I then removed the outer screen and cleaned the inner. Still the same result. It appears that these smudges or shadows are now all over the screen. Does anyone know if this could be the bulb starting to fail or something else. Any help would be greatly appreciated.

I swear that I recently saw, in a catalog, a device that lets you
turn a phone line into a cable tv jack.  It hooks up a phone jack
and cable jack in one room to a phone jack in any other room. 
I've tried several different searches on Google and other places and
haven't come up with the right phrase.  If you seen this also,
please point me in the right direction.

 This would be great at my parents new house so we don't have to run a long coax cable from a splitter into another room.

 Thanks!
