Question about Sampo PME-42S6 42 in. HD-Ready Plasma Television

3 Answers

Audio interference Hi all, I just re-installed all my audio/video equipment after a move, and I'm experiencing a loud buzzing coming from the Sampo plasma TV. Not only is everything in the setup the same as in the last house, but there was no interference last night when I turned everything on. I have the video running from the cable tv port into an HD cable box, then to the tv through component cables. The sound goes from the cable box to a receiver through an optical cable. There are also a DVD and VCR hooked up. Any thoughts on the cause of the interference or possible solutions? Thanks!

    When we move and reconnected the Sampo plasma, a humming sound is driving me crazy!

    We did not change altitudes and everything is connected the same that it was in the last home?

    When I turn volume down, I do not hear the humming noise.

    Suggestions please?

    We turned our TV back factory settings and it seems to work but then when we plug in our Cable it does it again. No idea what is going on here but it is driving us crazy. We did change our box and are thinking to going back to the regular digital box since we didn't have this problem before.

You need a coaxial ground loop isolator

The sound is coming from the back of the TV, and we did move to a higher elevation (2500' to 5500'). The buzz comes and goes - will the TV acclimate to the new altitude, or are we stuck with this annoyance?

Is the sound comming from the speakers on the TV or the back of it? Plasma TV's can doing buzzing sounds when moved to higher elevations.

    Most likely it will never go away period. In fact according to what I understand the life of the plasma display can be reduced somewhat.

On the tuner, only A.M., there is a buzz when the T V is on. Any thoughts ?

Your TV is emitting radio wave interference. AM is very sensitive to this type of interference whether it is from your TV, CD player etc.

Most electronics will leak some interference. Some are better shielded than others and will emit less.

Try to move your am antenna further away from the TV.

Hi i have connected all the cables up correctly & have it all working except i have some sort of interferance coming through.i have a contant crackling & on & off buzzing sound,sound like...

First thing: Make sure ALL and I do mean ALL of your interconnected equipment is POWERED from the SAME receptacle. Powering different parts from different receptacles in a building will surely get ground bounce buzz and ALSO subject the equipment to hazards of circuit damage.
The audio connecting cables should be BALANCED lines where possible... either XLR or TRS cables. Problems like you are having are common when CONSUMER grade equipment is mixed with PROFESSIONAL equipment. Anyway, get all the stuff powered from the same receptacle and get back to me if you still have the problem. Note you may have to run three wire extension cords if devices are separated a bit... the pro's have to do that to avoid noise. All devices should have three wire (grounding) cords and/or grounding wires connecting chassis...

Loud buzzing at the first volume setting

Check all your wires and make sure that none of the wires that are powering any equipment (including extension cords, power bars, and power cables on the unit itself) are running parallel to any of the audio cables going to your speakers or from your inputs to your unit. This could be what's called AC hum, which is caused when the electrical current causes interference that gets picked up by the audio cables and amplified by your system. Just make sure you move the power cords as far away as possible from the audio cables.

Interference audio and on-screen

Try an HDTV. If you only have a standard TV, try a different one. I had the same problem and then bought a 1080p 16:9 aspect ratio HDTV and everything cleared up completely (sound and video). Update the ps3 to version 2.2 as well (just came out last night). Good luck!!
