receiver HDMI light flashing

I just fixed mine with the same issue. The holding of the Advanced Surround button and Power button for five seconds reset the error, but a few seconds later it came back. So I ended up opening the unit up and replacing the short little HDMI cable connecting the front input board to the main HDMI board. This fixed the problem. Seems the way it was twisted in there damaged it over time and it needs replacing. Everything works as it should now. My model was a VSX-1023.

Related issues with HDMI have to do with the quality of the HDMI physical connections. These are mostly at the back of the top HDMI board on most Pioneer units. If you remove the top cover (side and back screws hold it on, then lift the back up, and pull up and out toward the back), you will see the top board.

You will see one HDMI cable going frontwards. Another responder here noted his HDMI connection was loose there. Try to tighten up that connection.

The side connections to that board are critical too. If the side connections are not tight, you may lose audio outputs. Try to pull those out and push back in.

If your HDMI signals ate noisy or HDMI video fails, I have also had to remove the top board to slightly re-compress the back HDMI surround ground shield. When an outer metal connection jacket gets bent open, the HDMI internal pins may lose good contact. The external shields can be gently compressed with a settable clamp, or pliers (the ViceGrip brand has an adjustable bolt in back to limit the jaws distance, and works well). Be very careful not to break any of the tiny soldered components under or near those back HDMI ports. Then reassemble the top board into the chassis and be very sure the side connectors are well inserted.

With luck, your Pioneer receiver will be fully operational and it's audio and HDMI back to full function.

This worked for me:

On Pioneer receivers, you unplug the unit, fully powering it down.

Plug it back in, but do not power it up yet.

On the front panel, find the button marked “Enter”. Depending on unit, this may be a single isolated button or a bar type button along a line of such bars.

Press in the Enter button and while holding that depressed, push the ON power button. Hold these in for several seconds, then release the Enter button.

You should see the “Reset [Yes]” type question. You can toggle between Yes and No with front panel Up and Down buttons. With Yes showing, press the Enter button to reset the entire receiver.

This clears errors in the HDMI, and also any other setting errors that you may have.

Best of luck —- Michael

Thanx for the fix. A defect HDMI cable was my problem.

Thanks it worked VSX329.. JUST ONE ADD ON DONT TRY THIS THROUGH YOUR REMOTE.. IT SHOULD BE DONE ON THE RECEIVER ITSELF

I have the same problem with my receiver and the most common culprit always seems to be your HDMI cable so what I did was I unplugged my HDMI cable with my unit on and the TV on plugged it back in and my picture and audio came back like it never happened always check your HDMI cable if it's old worn out or not securely in order and you might want to replace it

Have a VSX 43 Elite. w/ same issue. ( Blue flashing HDMI light). Unplugged receiver power cord. Plugged it back in and pressed the Power and Advanced Surround button together for 5 seconds Same issue. Tried the same maneuver 3 - 4 times and it came back up and worked but with crackling sound through the center channel speaker. This finally went away, about 10 - 15 seconds and now it works fine. Will see how it works the the next time. Not sure why this worked but it did. Like others, think it might also be an HDMI cable issue. Hope this helps.

My VSX-44's inner HDMI cable:

@davidhanna76275 Most likely no longer helpful for your issue, but may help someone down the road:

I just had the same problem on my vsx -329. Thank you for the advise on here. Also gave my receiver a little bit of tlc as I have had it now for almost 20 years.

Its the one with the 5 black wires and one white wire
