Re: Need Rf Ground Breaker Design, CATV giving me 1.5v from
Hi borber ,Rf-om something I really need to know , the LCD I got plugged my CATV cable , started to make some high pitched noise and I'm almost quite sure it didn't when I bought it. Could the voltage that kept flowing through the catv might have fucked something up on the lcd psu ?. As soon as I leave the lcd on the noise starts to go away , and whenever I change channels, due to the backlight on the LCD is makes some different whine until it normalizes , I don't think I got a defective unit, could this might have screwed up something on the lcd psu?. If thats not the case, what could be related to it, as long as it starts to heat up the noise goes away, quite odd. In relation to the catv filter I'm going to try what borber said with 1nf caps I mean the simple circuit from epanorama with 2 , 1Nf caps and thats it , or should I add an inductor? (what role will the inductor play? ) Thanks a bunch guys you're really helping me out on this ! we'll keep on touch
