Television and Home Theater

Hi,  I am trying to fix my 40 inch tv to the wall above a fireplace and I didnt want all the leads showing. At the moment my incoming tv aerial and sky tv aerial are coming in through the wall near to the window at th4e bottom of the skirting and its approx 5 meters to the position on the wall above the fireplace/

I have a sony bravia tv plus a surround sound which includes a dvd player,  plus a dvd recorder plus a video recorder/player all needing to be connected!

I JUST PURCHASED THIS TV ABOUT YEAR AND A HALF AGO FOR APROX. $1200. iTS HARD TO FIND ANYBODY TO WORK ON IT. ONE LOCAL "TV REPAIR MAN" HAS NO IDEA. I PAID ANOTHER $125 DOLLARS TO DRIVE 85+ MILES TO TELL ME IT WILL COST $750 TO REPAIR. MY PROBLEM IS AS SOON AS YOU TURN IT ON IT LIGHTS UP AND SHUTS RIGHT BACK DOWN. I WAS TOLD IT NEEDS A NEW HIGH VOLTAGE MODULE. IF ANYBODY COULD HELP ME OR POINT ME IN THE RIGHT DIRECTION IT WOULD BE VERY MUCH APPRECIATED.

When I turned on my 8 year old Sony KV36XBR250 this morning it had white lines from uper left to lower right and a slow rolling screen.  Audio is fine, picture is good except is looks washed out due to the white lines and dots.  Would appreciate some help.
