Thank You
Ha! I almost broke one of these today. The component is an inductor as noted above; you may have success to simply solder some lead wires onto it and put it back in place. Unless I'm mistaken, all that's inside that plastic cylinder is a ceramic coated wire of a specific diameter wrapped in a coil of a specific diameter a specific number of times... You could even make your own out of magnet wire from radio shack (I know I have in the past when I couldn't find an off-the-shelf inductor).

Got my SR606 as a refurb in Oct 2008 and other than one of the components inputs losing one channel within 6 months, has been working fine since then.

Now in the last month it has been giving me trouble with some audio issues. After correcting a loose center channel connection that was a global problem, I thought it might have been a problem with my Roku 3. But, after checking other HDMI inputs, it looks like a bad audio channel on just one of the 4 HDMI inputs. No issue with the other ports or OSD and no issue with video, except for some intermittent dropouts that I at first thought was a Roku issue.

Since I only have 3 HDMI devices, I am back in business now by moving the Roku to the unused input.
But, I probably have this repair coming up in my future, so appreciate the efforts of those who contributed to the DIYs

SUCCESS!

For the last year my 2010 TX-SR876 has been slow to handshake, requiring several minutes warm-up before it would successfully negotiate over HDMI but worked flawlessly otherwise. Oh, it would sometimes recognize my Comcast box on SD channels right away but failed on HD channels until several minutes of warm up. After reading much of this thread, I decided to try replacing the 100uF caps. The HDMI board has 5 of them on the top and 8 on the bottom. I ordered 20 Nichicon RS81C101MDN1JT caps from Newark.com. Based on some bulletins regarding the SR606 which should have little relevance to my 876, I decided to start by replacing C8609 (center bottom), although I planned to replace most if not all 13 100uF caps. After my embarrassingly primitive soldering skills nearly destroyed the board, I stopped after just replacing C8609 and tested the unit. IT WORKS! No warm up needed. Confirmed 3 times after several hours cold. Handshakes with all my components without delay. ALRIGHT!

Other than my poor soldering the only real challenge was the 5 wire power plug. I managed to avoid destroying that by reading that you had to press down on it to release the wires, documented in the first post.

Thanks to all the contributors to this thread!

Thanks for your post. I've got an 876 that I really babied. So found your fix interesting. How about posting on the 876 Owners Thread for other people that are having problems?

First, I would like to say, thank you, to all, for contributing all this info. I have a 706 that needs to be recapped. I have a question about how some of you guys are soldering the caps on the board. Are you guys pulling out the old legs and sticking the new legs through the board and soldering ? Or leaving them in and just soldering on top of the board ? I just watched the video on youtube and it looks like he just soldered on top ?

Also, I know this isn't the 706 thread but i see some those guys posted in here. It seems all the links are down for the 706 service manual, Can anyone help with that ? I'm wanting to order everything soon (Tonight) and i would like to see what other caps i could buy and replace. Thanks
