My proscan is buzzing and pix is flickering when the power is on.

I found this solution on another review, hope it works
Model Number: Proscan 26" LCD HDTV w/ Built-in DVD Player26LB30QD "pro: good price, TV picture is clear and DVD player is compatible well.
con: sound noise
There was hum when I first turned the TV on, then I followed these instructions (found it from other review) to fix the hum issue:
1. Turn tv on
2. Input mode should be tv
3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone."
It works,no hum."

I had the same problem at one time, however it was only on one channel, WGN to be exact, it only did it that one time and only on that channel, call your cable company maybe they can fix it through a filter or something.

I just got my proscan 26LB30Q yesterday and it is also buzzing. The picture is good though. I thought it was my electrical outlet, but its the Tv
