Sharp TV won't turn on

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?

    my tv wont turn on

  • levia844 Mar 13, 2009

    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.

`How do I fix my LG tv? It's making a high pitched noise and there is a black screen, is it fixable?


Get it to a tv dealer but my guess is its died. It may not be economical to repair but you may be pleasantly surprised and its a small job. LG are usually pretty good so I'm surprised its gone at this age.

This set has a shorted horizontal output transistor and possibly a bad high voltage transformer. If you repair the set, also solder the horizontal drive for the transistor listed above. Try www.encompassparts.com for parts. the h-ouput transistor is p/n: 223942 and the transformer is 223952 .Thanks and good luck.

I got a free sharp notevision PG-m20x. I plug it


if you don't hear a high-pitched whir, the colorwheel needs replacing. if you do hear it, the lamp may need replacing. if the lamp is new, there is a power supply problem.
