Sharp TV won't turn on




By savi0027 on Oct 30, 2007

" "
I got this free TV from my parents because it won't turn on after only two years.  When plugged in it makes a high pitched pulsating sound.  It took the back off to find out where it was comming from, it seems to be coming from the center of the circuit board.  I read somewhere that it might be a bad connetion with one of the diodes.  Is this something that i can do on my own?

Same Problem

-   when i plug in the tv, it makes a ticking sound. when i push the power button, there's no power. i opened the back cover to see where the ticking is coming from. i thought it might be the fuse but it wasn't.
as i listened closely where it was coming from, it sounds like it's coming from right center of the board at a square piece with yellow around it.
is this something i can fix myself? and where can i get this part?
thank you for your time.
