    I’ve got a JBL ES250P sub that started humming a few years ago. It still works, but it hums whenever it’s on. I’ve tried multiple outlets and It doesn’t matter if it’s plugged into the receiver. I’m pretty confident one of the filtering caps needs To be replaced, but I’d like to be 100% sure...
  4. Speakers
    I just acquired some Polk S15 bookshelf speakers and one of the cabinets is scratched up pretty bad for my taste. The veneer seems like a dense plastic of some kind, is there anything I can do to buff these out or make them less noticeable? Any advice or experience with this kind of thing is...
  5. Screens
    Well, I've read questionable reviews about Elunevision but sadly I didn't take heed and bought one anyways. Since day one, the screen had been unreliable and with some minor defects. Both the vendor and product representative had ignored the issues. Finally one day in the middle of the night...

    I pulled the trigger on a Boston Acoustics A7200 (Sherwood A-965 Clone). UPS just dropped off the shipment today and the amp has quite a bit of damage.

    HI all, I bought this in 1996 as part of my HT setup when I had four inputs, SACD, CD, Blueray, PS2-5 and enjoyment of my physical media. The issues: Over time there would be a rather noticeable/loud clickity-clack coming from the unit and then death of the one or all of the audio channels...
  11. Receivers, Amps, and Processors
    I have this Marantz SR6006 that works very well as far as making sound out of speakers is concerned. However, it developed a problem that it switches the sound output from speaker to headphone outlet on its own for no obvious reason. I had to plug in and out the headphone a couple of times to...

    Can someone help me to find service manual RRV4526 which is the one that contains the diagrams for VSX-824. Unfortunately the one on ElektroTanya is RRV4520 which doesn't have any schematics. I know RRV4526 contains the schematics because it is mentioned on the front page of RRV4520. So if...

    Hey folks, my PMA-2000R amp is not working anymore. So it has had some issues before where the input selector goes crazy while playing music, and it switches between all the inputs on its own until I turn the input selector. And then yesterday, the receiver won't output sound anymore. Before I...
  17. LCD Flat Panel Displays
    Hi everyone. I have a UN65JS8500 LCD 4k TV that's, I guess, 5 or 6 years old now. This year I changed my setup such that a pc drives everything now. The TV is basically now a monitor. Since then I've had HDR engaged much more often, which really cranks up the backlights (side-lit). A few days...

    I’m more or less a newbie looking for some DIY advice as I attempt to repair or replace the 10 inch passive radiators on my Paradigm seismic 12a. I’ve tried researching on my own without much luck. The sub had developed a bit of a rattle which I now realize was likely the weighted portion of...
