Re: MAGNAVOX no picture powers LED 47MF437B/37
I have the same chirping issue with the power supply for this TV. I followed all of the suggestions in this thread. Although I think only the 2200 uf capacitor was bad, I replaced the 4 capacitors (one 2200 uf 16V (C955) , and three 1500 uf 35V (C951, C952, C953)) and 4 diodes (ZD904, ZD904, D926, D928) and I still have the chirping. Any ideas before I throw in the towel?
Thanks!
