Buzzing sound over LED TV Speakers
« on: April 10, 2015, 02:14:40 pm »
I have purchased a MED250X. As soon as I power the unit up there a buzzing sound every few seconds and very loud even if the TV is muted or the volume is set to zero. The unit is connected to a surround sound system and there is no buzzing sound over the amplifier and and its speakers. As soon as the first movie is played a few seconds and I return to the main menu screen the   buzzing has stopped. A bit irritating every time you start up. Will do a firmware upgrade and hope the buzzing stops. Any info on this.
Very happy otherwise with the purchse!! :) :)

I have Sinotec LED TV. HD Cable out from 250x to HD in on TV. Optic cable out from 250x to Sony Surround sound system amplifier optic in. I have done a firmware upgrade and this loud bussing sound persists on start-up. As soon as you have played any vidoe for a few seconds and return to the main menu the "buzzing" sound has stopped. The buzzing sound is every 4-6 seconds .

This is strange - must come over hdmi as you dont here it on your Surround set.
Do you have another TV you can try your unit on to see if you hear the same?

I have tried another HD Cable the one supplied with the unit. I only have one TV Sinotech. I am sure there was a similar report than mine also on a Sinotech TV. The noise remains as initially reported. Firmware upgrade done.
