mine is samsung lcd tv la32b350, almost 5 years old na, what happened is nawala yung picture but still may sound pa rin sya, then after looking closely, i can see a picture, so the problem is i think the backlight. called the samsung service center, then after 2 days, may dumating na technician, checked the unit, ang diagnosis nya is the power supply kaya palit power supply daw, so medyo naguluhan ako, bakit power supply kung may power naman yung tv. i asked him kung sure na power supply ang problem, and how much ang cost, sabi nya na kesyo kulang na daw yung power going to the panel, and the cost daw is yung office ang makakasagot. after 2 days ulit, service center called me and the price of the power supply is 5k+ less yung 650 na check up fee. i asked them na baka naman pede gawin na lang yung power supply, hindi daw pede kasi assembly type daw. haaayssss...baka mamaya ipagawa ko tapos bigla na naman mawala yung picture then sasabhin nila is panel na problem. sayang lang ibabayad ko power supply.
