Video Noise coming from LCD TV (bassy noise)

someone guide me

my 32 inch Sharp LCD TV is connected with one Hathway set top box (not DTH) and a PC with HDMI cable.

now a big trouble here is that initially it was working fine but now when i switch to my STB (which is connected through the analog red white and yellow cable) there is sometimes (very often, after raining) a bad noise in the audio(zzzzzzzzrrrrrrrrrr...) and video(some broad lines) as well.

At the same time either if I disconnect the HDMI cable from PC (or from the TV) or I remove my CPU power plug or if I disconnect the TV Cable (from STB or from the wall (our TV cable is under wall)) the noise goes away.

I think this is because of getting the cable wet in rains, but I wanna watch tv and enjoy PC on this same TV. tell me what to do :O

actually, one of my three HDMI has stopped detecting the input due to this noise.
