PIONEER AV RECIEVER VSX-1023 WON'T TURN ON, & red blinking HDMI light appeared?

Have you solved ???? Thanks .. I have the same problem

try holding the advanced surround and power button for about 5 seconds

Try to do the factory reset on the Pioneer:
Switch the Pioneer into standby (turn it off).
1. Simultaneously press old the buttons on font panel for 5 seconds - BAND & STANDBY/ON
2. "Reset" on the front panel press
AUTO SURROUND/STREAM DIRECT
3. Then press ALC/STANDARD SURROUND

OR

Simultaneously pressing "down" and "on/off" for 5 seconds to reset the Pioneer

try holding the advanced surround and power buttons.

You guys mentioned the reset via the front panel, and I tried that with this very same issue on my VSX-822-k and it worked!
thought I would post the instructions for anyone else that lands here:
Reset the main unit if the receiver is generally not operating correctly. Switch the receiver into standby mode. Hold down the "BAND" button while pressing the "STANDYBY/ON" button for about two seconds. When "Reset?" appears in the display window, press the "AUTO SURROUND/ STREAM DIRECT" button. "OK?" appears in the display window. Press "STEREO/A.L.C." to confirm. "OK" appears in the window. The system has been reset.

The solution to using 901's in a multichannel rig works best when you have individual Front Right and Left Pre-Outs but this receiver doesn't have them so a compromise is in order.

First some background.

The use of 901's Active EQ (or any external processor) in any digital AV receiver setup for anything EXCEPT STEREO listening through the 901's alone requires you to have a separate amplifier for them and to avoid having to use a Tape Monitor which could introduce proprietary and potentially damaging Active Equalization back into anything in the AV Receiver with its conventional speakers.

In an AVR, if you activate any Tape Monitor circuit at all, you will kill any digital sources. That is a function of AV receivers in general, nothing to do with 901's. Your Pre-Outs get us around that possibility and limitation but it also means you need a moderately powerful amp for your 901's.

This works for all models of AV receivers when you want 901's as Front L&R speakers...

Get yourself a nice separate amp, draw the Front L&R pre-out signals from wherever you can find them, in your case maybe the CDR or DVR/VCR outputs.

On many AVR's, there is a pre-amp out for every channel in case you want to run external amps for any channels. That is how my old Pioneer VSX-36TX is equipped. For others (yours), you have to borrow the signals from a typical CDR or DVR/VCR Output RCA pair. Just remember, AV receivers disable digital inputs as soon as you switch in a Tape Monitor, so choose one you won

you can "release" the error by pressing the "down arrow" and the "zone 2 on/off" for 2 seconds.

If the light on the media reciever doesn't come on then the power supply in that needs to be replaced by a service tech. If you disconnect the 2 cables from the media reciever and the panel and then try to turn on the panel it should light with red and green squares for a few seconds but will turn off as it needs the media reciever to be connected.

I'm having the same problem. I read on a kind of VSX-D510 eletronic manual tha says POWER OFF "When displayed, it's the case where DC is in the output of AMP".

Do you know what does it means? How can I solve the problem?
