Got the above problem on a single frequency. As such, all those channels that belong to that particular frequency emits screeching sound and pixellated graphics. Saw some bros recommended a CableTV signal amplifier. Got one from SL Tower but failed to do the job.
In the entire troubleshooting process, I accidentally switched off my wireless router and the pixellation problem all disappeared. Did a few test and confirm the interferences was from my own wireless router being too near the DM.
Hope to share this experience with bros caught in the similar situation.
PS: As such, my cable signal amplifier became a white elephant. Bought at $37, willing to let go at $20 (fixed price with store receipt) since it's no use afterall. PM me if interested. The brand is Sound Tech.
Thanks.
