Re: LF501EM5F No Power, Chirping/Beeping Transformer
I have a Magnavox 46me313v/f7. I checked c3214 and sure enough it was shorted and fixed the problem Good Call. Also Budman I took your advise and got the LED Tester from SJ and it has already been a big help. It's pretty cool. Thank you both for the good advice! -

Re: LF501EM5F No Power, Chirping/Beeping Transformer
I think maybe I got a hold of a bad new main board. After getting the leds on found I can't turn the tv off with the on/off button, I don't have any on scree display either.Leave a comment:

Re: LF501EM5F No Power, Chirping/Beeping Transformer
I read through the posts and first I jumped 3.3v to bl-sw and got no change. When I added a second resistor to bl-adj the led's did light up so a little progress was made.Leave a comment:

Re: LF501EM5F No Power, Chirping/Beeping Transformer
I have the same set(lf501em5f). It was also chirping and I also changed the main board. I now have the same thing as shadetreetrader11. 47 v at the led plug. I'm not sure yet but I think the problem is with the bl-sw circuit. I have 3 jumpers (j116,106,103) all labled bl-sw but all three have 0v.Leave a comment:
