got this tv ive been struggling with...when i first got it, i diagnosed that the inverter board was failed and replaced it. but when i replaced the board i noticed that now the backlight and picture came on but i am hearing a really loud annoying high pitched noise from the power supply. so i replaced the power supply just today and apparently people on ebay dont know how to test anything before they declare its good and ship it out, because this power supply makes an even louder high pitched noise and only makes the backlights flash over and over again...it cant keep them on. so now i have to return this power supply...and im back to my original psu that works but makes an annoying high pitched noise when switched on
i think i isolated the part of the psu that is making the noise. its the big yellow thing in the second picture.. is this a transformer? can it be repaired or replaced? i was hoping to get away easy with just buying a board for 25 bucks but if i cant even trust theyre going to work, i might as well fix it myself...never had this high pitched noise problem before. ideas anyone?
