I have a really annoying problem in my apartment. MY TV picks up most electrical noise from other apartments, from me switching other equipment on/off , from upstairs laundromat etc.. The noise appears as horizontal lines of snow.
The other problem is that my PC sound setup is also affected - I can hear a click at the same time I see the noise lines on the TV.
I've tried surge suppressors, fancy powerboard but they don't really help and I don't have enough knowledge on this matter. If anyone can help I'd appreciate it.
thanks
