Hello I have an older Samsung HLT5075S. The bulb went out about 7-8 months ago, but I just now replaced it.
The tv came on fine, but there is now this loud hissing/popping sound coming from the internal speakers.
I can even turn the volume all the way down and still hear it. I can hear it more prominently when there are higher shades of white on the screen. Its very loud and annoying. I thought maybe it would eventually work itself out, but its not.

Any ideas?

thanks

hello,
sounds like there is some interference... it can be your input board, when you replaced the inputs, did you make sure not to plug anything differently?

Yeah everything is plugged in fine. But get this. It stops after about 15 mins. I guess it's warming up? I dunno

I think maybe an input board is about to go out... keep us posted if it gets worse!
