I have a samsung TXK2754. I finally got it to turn on, except it makes kind of a chime noise then goes to a screen that has a grey background and about 10 thin while lines going horzontally. I have read a little about the problem already and i was thinking it could be the high voltage circuit or the horizontal transistor. How would I going about testing to see which one it is, and if it is broken is there a guide to help me replace it myself.
Thanks Very Much...
