  1. Digital Projectors - Under $3,000 USD MSRP
    Hi, I need help. After 10 years of Good work my projector had more and more white spots, so changed the chip. YouTube - everything worked good. Bit afterwards I had vertical artifacts with reflections. By now I tried to fix it for 5 times. But no success. I Even cleaned the connection between...
  2. Receivers, Amps, and Processors
    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...
  3. Receivers, Amps, and Processors
    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...
  4. 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...
  5. DIY Speakers and Subs
    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...
  6. Receivers, Amps, and Processors
    Hello Everyone - I am in need of a repair to my MCA-20 amp. The binding post molding for the left channel has broken off and will not hold the posts to the unit (please see attached photos). I tried contacting Anthem in Canada 3 or 4 different times and for whatever reason, they will not...
  7. Direct View (single tube) CRT Displays
    Hello, I'm new to the forum. I just picked up a Sony KV-32FS120. It appeared fine when I picked it up but after transporting it home I noticed some issues. I did some research and I'm having trouble figuring out the solution. First, the image was tilted. I fixed this using the menu. I will later...
  8. Plasma Flat Panel Displays
    My Panasonic has suffered a lightning strike (I was there when it hit and popped!) The Main Video board has died. This is the second time this board has died, and instead of getting it repaired again, I decided it's time to upgrade to 4K. So I bought a Samsung Q90T 65 inch. It has some quirks...
  9. Digital Hi-End Projectors - $3,000+ USD MSRP
    Hi there, so I got an old Barco Graphics 6400. Yes, its just XGA but for the occasional outside "movie theatre" it will suffice. But, it seems that the LCD panels are out of alignment. They are about one to two pixels shifted to each other, e.g. green seam on one side, red or blue on the...
  10. Digital Projectors - Under $3,000 USD MSRP
    Hi all, I've been having issues with my Benq w1070. It's 5 years old now, so probably time to get something new, but I thought i'd try my hand at some home repair. I think I may be in over my head. The initial problem was, what I thought, a color wheel issue. I took it apart to try and see what...
  11. Receivers, Amps, and Processors
    One of the speaker output ports of my AV Receiver Marantz SR 5007 has a bad connection: there is a lot of static coming from the speaker connected to it which I can stop if I jiggle the cable screw at the port and find the right position. I've tried to connect different speakers and use...
  12. LCD Flat Panel Displays
    Didn't see an Owner's Thread for this newly released TV so thought I'd start one. Just picked up the 65" TV from Costco May 25th & had it up & running in no time. Click here to learn more about what the P Series Quantum brings to the table: Vizio P Series Quantum X. TechRadar review...
  13. Digital Projectors - Under $3,000 USD MSRP
    Help! I purchased an Epson Home Cinema 4000 on eBay last year. It was a new projector, but from a 3rd party. It died over the weekend. It will not power on. After a quick google search it seems Epson has and issues with the 4000 and 5040 lines with the power supply failure. The main frustration...
  14. Subwoofers, Bass, and Transducers
    I inherited a very nice collection of Onix Rocket speakers from my late uncle who was also a frequenter of this forum (none of my other family members had any idea what to do with his pro home-theater equipment). Anyway, the subwoofer, an Onix Rocket UFW-12 had the amp start to fail (weird...

  16. Subwoofers, Bass, and Transducers
    Hey all, I have noticed my JM Lab/Focal sw700 (yes it's old) has been acting up. I'm getting a clicking noise, the rate depends on the load. I suspect it could be the switching power supply, and not the speaker itself. Are amp plates repairable? I'm handy with a soldering iron. If no, would...
  17. Camcorders
    Hello. Is there a service manual download source for this camcorder in the internet? Two black screws with coarser thread, but I cant find the holes :confused (after glueing and strengthen a part of the hull with J-B Weld 2K glue, be careful when tightening the tripod plate, the case is thin...
  18. Digital Projectors - Under $3,000 USD MSRP
    Hey! So, not sure if I'm posting this in the right section, but I picked up an Epson HC2045 for a killer deal off of Craigslist. Upon setting it up, I noticed the center of the image has a green hue/bleed of color. High contrast scenes, like the red Netflix logo on a white background, looks...
  19. LCD Flat Panel Displays
    Hi guys, whilst moving houses something has fallen onto the screen of my TV and damaged it. I've uploaded photos, just wondering if its something that's easily fixed or if its cheaper to buy a new TV? I've replaced laptop screens before, so if it doesn't cost much / is relatively easy to...
  20. Home A/V Distribution
    Hi All, I have a Russound CAM6.6X Multi-Channel Amplifier and the left channel for zones 1-3 appear to have died. I've contacted Russound, and they are no longer offering factory service for these. They told me to buy a new unit. However, I have noted that there are still CAM6.6 units readily...
