ONKYO receiver TX-SR-806 HDMI handshake DIY fix (with photos)*updated photos May 3 2013 (at bottom of this post)not long after I made this post, a forum member contacted me to point out that 3 capacitors had wrong polarities. Immediately I fixed it and updated my photos.
A while ago I started to see green lines after I turned on my receiver and switch input for my TIVO (all done using an Activity on my Harmony One). Then I started to search the internet and I found this thread. I looked at the video on YouTube (great visual aid by the way). I recommend you watch the video 2-3 times before attempting this fix. I decided to purchase the capacitors and proceed with the repair. My receiver was originaly purchased in Feb2009.
Basically the repair involves replacing the defective capacitors that are on the HDMI board. You will have to replace (13) capacitors, 5 on the top side and 8 on the bottom side. Original capacitors are Philips 100uf/4V. You can use higher voltage, like 25v, they will be a bit bigger. I found mine on eBay (25 surface mount capacitors for $6 shipped). I recommend you buy more than 13, in case you break one or two.*for better viewing of my photos, please download them to your computer then you can zoom in.What you need:
1. soldering iron
2. solder (I use Kester 60/40)
3. desoldering pump
4. philips head screwdriver
5. long nose pliers
7. flat head screwdriver
8. 13x100uf/25V capacitors
9. Black SharpieUnmount HDMI board:
1. Unplug your receiver and place it on a flat surface, make sure you have good lighting, I used a desk lamp.
2. Remove the (3) screws located on the back of the receiver and the (3) screws located on each sides of the receiver, then remove the cover
3. Locate the HDMI board, it's the circuit board that sits behind the HDMI connectors on the back.
4. To remove the HDMI board follow these steps
1. remove the 5 wires connector, pull gently on the wires using a long nose pliers (don't pull on the connector)
2. pull on the circuit board so it detaches from the support posts.
3. pull on the flat cable, pull gently using your fingers no tool involve
4. detach the wire from the little white plastic holder
5. remove the screw that holds the HDMI board to the side circuit board
6. remove the screws that hold the HDMI connectors (6 connectors X 1 screw)
7. hold the HDMI with one hand (5 wire connector side) then pull gently away from the 2 large white connectors.
Now the HDMI board should be detached from your receiver.
Place the HDMI board on a clean surface (I use a placemat)
Turn on your soldering iron, make sure it's ready when you need it.Replace faulty capacitors:
1. locate the 13 capacitors (use my photo) 5 are on the top side, and 8 are on the bottom side of the HDMI board. They are identified by 100/4V.
2. Using a Sharpie I put a dot on top of the faulty capacitors, this makes them easier to locate thereafter.
3. The black semi-circle on the capacitor indicates the negative (-) side
4. Using a Sharpie, place a dot on the circuit board near the - side, this will be easier to remember the correct polarity when you install your new capacitor
5. To remove the faulty capacitor, using the long nose pliers, pull gently and move back and forth until the capacitor detaches from the board
6. Then you're ready to solder your new capacitor
7. Prepare your new capacitor, remove the black plastic platform, then fold the lead (like the video suggests)
8. Using your soldering iron and your solder, melt solder into a little bead on each sides where the leads of the faulty capacitor were located.
9. Using tweezers hold the new capacitor with one hand, with the other hand hold the soldering iron, melt the little bead of solder as you place the new capacitor in place.
Repeat for the other lead. Once it's soldered correctly, I like to try to move it with one finger just to make sure it's solid and secured.
10. Repeat this procedure for the rest of the capacitors. Be patient, take your time.
Once all (13) capacitors have been soldered re-examine both sides of your board, make sure the new capacitors are well sit, polarities have been respected etc.
Reinstall your HDMI board and screw the cover back.
Enjoy your receiver and be proud of yourself.Edited by reggiefl - 5/3/13 at 9:34am
