    Found problem in Kenwood KR-V95R

    Yes yes. It's like the car battery thing that you find on the garage floor that doesn't work, but this isn't that. [blame that on magical cement :] I had upgraded from 2 channel to surround sound. I re-used the main speakers so had no more use for the stereo. The stereo is great, and was an...

    Found problem in Kenwood KR-V95R

    First time posting here. I give my niece my Kenwood stereo only to find it wouldn't power up. It had sat for a few decades on my basement floor. Being an old lazy engineer I checked Google first and found this site. EP seems to have better answers that 'Just buy a new one' so that was good...
