  1. DIY Repair and Maintenance
    Have a question regarding a Denon AVR 2311ci Receiver that needs repair. Using it for an audio-only setup, driving two speakers (set to 2CH mode). The unit powers up without any issue - no error codes or issues reported. Have a CD source connected to it. I do not get any audio from my speakers...
  2. Home Theater Projectors
    Hi, A few weeks ago my epson projector, just over night when i left it on, decided it didn't want to work anymore and had an auto iris fault. I checked online and saw that the local repair centre was 3 hours away with £400 fees with no guarantee on fixing it so I thought id try repair it myself...

    My MRX 700 made an exploding noise through the speakers and shut itself down - twice. Worked fine right after but next day, the main left speaker out is nothing but loud static regardless of input or volume. I swapped the cables and outputs and it is definitely the main left speaker output. I...
  4. DIY Repair and Maintenance
    I have a VPL PX15 - I recently replaced the lamp - while I was doing this I blew out the whole chassis because there was 15 years of dust everywhere. When I fired it back up there were globs of dust spots in the picture - mostly visible on a white background. Thinking this was dust spots I took...

    I bought an LG 55" OLED (55EG9100) a little over a year ago, and it has provided the best image quality I have every seen. A couple weeks ago the screen did this (see photo). I am concerned that I have a bad panel. Whatever has caused this, is it repairable? I am just past the 1 year warrant...
  6. DIY Repair and Maintenance
    Right now, my TV is flashing green light after a convergence repair. I have just replaced the DM caps and I still have the same problem. I'm hoping to find some help to keep my Mitsubishi WS-65869 going for another year or more until OLED's mature a bit! The initial problem was that the TV...
  7. Home Audio Subwoofers
    I picked up a used dcm sub 712 off of criaglist (I know, I know...I deserve that one) that sounds good at lower, but turning it up a bit, it sounds like there's a rattle going on when the bass gets good. Should I find a replacement driver or replace the whole unit? I don't have much to spend...
  8. DIY Repair and Maintenance
    Hello my new friends! I was wondering if any of you could be of assistance. There hasn't been a thread about one of these ancient TV's in a while so I figured I may as well start my own. I did some research beforehand which is what led me to using information on this forum to attempt this repair...
  9. Two Channel Audio
    I was hoping to get some thoughts on what might be wrong with my speaker's tweeter. I've attached a summary of nearfield measurements I've done on my good speaker, the bad speaker and the bad speaker after I opened it. The bad speaker had an indention in the wire mesh covering the tweeter...

  13. Home Theater Seating and Accessories
    I have a 3-seat Benchcraft electric theater seating setup and one of my seats will recline but not come back up. I believe it is the switch. It appears the company has gone out of business. Anyone know where I can buy a replacement switch?

  16. DIY Speakers
    I have some Infinity RSb's (circa 1978) that my wife and I love. I'm resigned to the fact that that our luck with the EMIT tweeters will run out sooner or later. Of course they are no longer available and even if one or two could be found used we'd just be trading one old tweeter for another...
  17. Home Theater Projectors
    After about five year's use, my projector went south. I'm not completely certain whether or not the timing is coincidental, but I had just added a PC to the setup. The PC applied yet another update, and during the reboot, when the video mode changed, I was treated to this image (well, this is...
