    I am having the same problem, but only have 2 10's under the back seat of my truck and haven't touched the radio settings in a month. Just started doing this today, and I reset it and it does the same thing after a few minutes. Any help would be appreciated.

If it is only doing it over 30 then you need to turn down the bass level on the deck and make up for it with the subs sounds like its putting out too much juice. also if your car has a factory amp for your door speakers ect make sure that your factory speakers are the same ohms as the cd player which is 4ohm ,most fancier car speakers are 2 ohm. if that is the case the amp on the cd player is going in to protect mode to prevent frying your factory amp if you have one. check all your wiring from the cd player to the car and make sure it is all properly hooked up and there are no crosed wires. or wire hooked up incorrectly. also make sure the amp wiring kit is big enough gauge for the amp. make sure its not the amp that runs your subs that is cutting off the HU.

How do I reset the protection circuitry on Yamaha RX-A820?
press and hold the 'tone control' and 'info' buttons and press power. This will release the protect. The first thing that show on the display will be the protect code to tell you why it shut down. If it turns right back off, then you most likely have a short in the amp that will need to be repaired.

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?
This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

No video or audio, but red blinking light is flashing
The Unit is Shutting itself down to protect itself from more damage, the light is blinking to let you know there is a problem, the problem could be a number of things, check the horizontal output transistor. It's a good Place to start for shut down problems

The protection modes in these units ****. Most new units have them. What I do is turn down settings on deck and turn up amp as much as possible. Then the protection won't turn on because you won't have to turn it up as high.

I was watching it and it just shut off when i turn it on 3 seconds later it shuts off again
this set has a self diagnostic feature:

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;}


UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

I have a Philips Plasma tv 42pf5321d/37 with sound but no picture
Thats the great sound of Exploding capacitors on either the power supply board. or another one in there. Now the set is in fault protection. It tried to warn you with the RED blinking LED that there was something amiss by shutting itself down. When you unplugged you reset the error and allowed it to do it again.

Headunit power problems
Hello dobbyville11,
It might be a few things but here is what i would check 1st, pull out the head unit make sure all the wires are pushed in all the way. The second thing i would suggest is checking the connection to the battery and ensure that the ternimals are clean and a good connection is available.
If there is something else it might be that you hold down a button while it starts, I know of some headunits that need this.
Please post what you do and how you did it. I look forward to your post.

Blinking Standby
regarding the Pioneer VSX-912 blinking standby light. This is how you reset it; press the "advanced surround" and the " enter" at the same time for about 3 seconds. Make sure you press the ENTER on the reciever (its the one on top next to the small dial) If you press the "ON" instead of "ENTER" it will not work. If an error message comes on and shuts the unit down, just reset it again. This should save you some $$$$. To bad Pioneer did't put this info in the manual.
