i know im a) New and b) reviving a very old thread but since it was this thread that led me to a partial solution to my problem i thought id ask here.
I have an LCD tv where this component blew (BM2576) and i switched it out for an LM2576 T 5.0 .Now it powers up and briefly shows "no signal" on the screen as expected but quickly fades out leaving a veeeeeery feignt picture suggesting a drop in voltage.
could enyone enlighten me as to what may have gone wrong? if the ground isnt rock solid would that equate to a drop in voltage.
