Hi everyone! I live in Sweden, and am new to the forum. Bare with me if my English not always is "top notch"!
I purchased a T757v2 two weeks before this Xmas. A great piece of equipment! However, there are a few issues with the T757. I state the rest of my audio/video-system for reference, all devices are connected to the receiver:
-Dali IKON 6 Mk1 front speakers
-Dali IKON 1 Mk2 back speakers
-Dali IKON Vocal 2 Mk2 center
-Dali IKON Sub Mk2
-Thorens TD318 MkIII turntable, through a NAD PP-2i Phono Preamplifier
-Panasonic TX-P46G15e plasma television set
-Motorola 1910 ATSC tuner
-Other devices connected to the T757: gaming systems Wii (component + analog audio), Wii U (HDMI), PSTwo (component + optical audio), PS3 Slim (HDMI)
The issues at hand:
1. I have noticed that when I turn on the T757, it feeds all speakers in the system (except the sub woofer) and the headphones with a high pitched noise
, like a high frequency “buzzing”. The noise is low in volume, but quite noticeable.
It is not affected by changing Listening mode or adjusting the volume. However, when I change source
on the receiver the noise disappears. Most often it is enough to change source once, but sometimes I have to do this operation two or three times until the noise disappears. I executed a factory reset, but no luck in solving the matter
I have read that power cables that run too close to speaker cables might have a negative effect, so I have tried only running the receiver and the front speakers (no other equipment in use at the same time), but no effect on the described noise.
NAD suggested I should exchange the receiver and get a new one from the dealer, which I also did. The problem is however present in exactly the same manner on the new receiver.
Does anyone recognize this problem? Suggestions?
2. I also noticed that the TV-display sometimes shows a uniform, yellow-tinted screen
instead of an actual TV-picture from the ATSC tuner.
This occurs when:
- I start the ATSC tuner before turning on the NAD T757, or
- when I have been watching TV through the ATSC tuner, switch source on the T757 to for instance CD-player, and the again returns to TV through the ATSC tuner.
I solve this problem by switching the ATSC tuner off/on, which causes the yellow screen to disappear and then the display once again produces the expected visuals (TV-program).
The ATSC tuner is adjusted to output 720p and digital sound. It is connected to the T757 by HDMI.
Any suggestions on solving this matter?
