We have a Phillips plasma tv and the picture pixelates randomly and freezes for about a second and sound breaks also. We have had everything checked and have been unable to find a solution. The latest internet research has led us to think it may be the coax. Can you help?


In my openion, Its problem of hardware in your TV and signal processing circuits are involved. It might be problem of Firmware (programe to control the performence over all) Philips can advise you better in this regard.
