Samsung projo spt-521j with no tuner action, shows only snow on every channels. I've check the switcher for bad soldering,
it is ok, this tv has a switcher going to 2 tuners , tried inputting signal directly on each tuners, still only snow in pic, and when using inputs, pic is ok.

So I know tv is ok. Also tried rescanning the channels, nothing . Any hints for this one ??
