Re: Sharp LC-32GA6E Stuck in standby

Just started all over again, im getting 0v to the bridge reticfer

DMM set to 600ac, probes to snake signs in the middle or bridge reticfer = 0v
did fuse checks f201, f202, f203 all are ok.

When i probe D763 i get 245v,

How do i go about testing IC's ic701 & ic703

0V ac doesn't matter if ICs are bad you need to fix this first, what do you see across two middle pins?

In the picture from post #43 the 2nd pix, the circle is on ic703, one o'clock from the ic703 is D763 im getting 245v when probed.

No relay click when powered on I guess.
There are probably two bridges one standby one main.
