Question about Sony Audio Players & Recorders
I have noticed a high pitched noise for a few weeks now, and I was able to pinpoint the issue to the LCD screen on the receiver. When I change the dim settings for the LCD screen, the tone of the noise changes. It is the deepest on max dim and the highest pitch on no dim. Also, I plugged the receiver directly into the wall (as suggested by Sony support), and that did not change the high pitched noise issue. Are there any other possibilities that could be causing the high pitched noise? Any help is appreciated. Thanks.
The problem is with its backlight inverter board. there are some step-up transformeres [small ones] fitted on board. If any one's core bacome loose this fault will occur. Just open the TV and listen to which one makes hi-pitch noise. Replace it, if you can buy it from the electronic market at your town. In most cases, the inverter board needs replacement.
This board can locate on the right or left side of the panel, fitted vertically.

This model requires a "Phono" input. This will give you the best sound. Once you hook it up correctly, make sure the volumn is down or you will blow the amp.

SOURCE: Can I connect a passive
No. Like most AVR's it only provides a Line Level output for an externally powered subwoofer. Get a separate amp for the sub.
