This is called the "protect mode" and it does this to keep the unit from more damage, meaning that the unit has some type of damage now and if it were to remain on it will cause more damage.

Most of the time this will happen because of a bad channel in the amp circuit. On more rare occasions it is the power supply causing it. The only way to fix this problem is to repair whatever damage has been done to it.

It will take the proper tools and some electronic troubleshooting skills to fix it. If you have a multimeter and soldering equipment I can help you with this and tell you the most common places to check for problems, but it will require some minimal skills on your part like being able to identify certain parts and be able to pay very close attention to details, and understanding certain electronic terms. If you would like to try this yourself let me know, otherwise, you should take it in to a service center and let a professional check it for you. You can get an estimate first before deciding if it is worth fixing.

Standby indicator flashes


When the "Protection" indicator comes up the display panel of my receiver or the On/Standby LED is flashing, does that mean my receiver needs to be repaired?
The "Protection" light comes on when the receiver's current sensing and thermal monitors detect some unusual operating condition that, if left unchecked, might damage the amplifier. This can happen if there's a dead short in a speaker wire or if you're using very low impedance loudspeakers at high volume for an extended length of time. On older model AVRs you may see the word "Protect" on the receiver's display. More current models will indicate a flashing red light on the Standby LED when a Protection circuit trips
n thermal cases, the circuitry will automatically reset after a few minutes of cool down and the Protection indicator will go out and normal operation will resume. If the protection light came on due to a speaker wire short, low impedance condition or a bad speaker, the receiver's power will need to be turned off to reset it. Before turning the power back on, all speaker wire connections should be checked for their integrity at the receiver side and at the speaker side. If the protection light goes on immediately after you turn on the receiver, disconnect the speaker wires at the receiver side and retest. If the receiver's protection light goes off, then there would still seem to be a problem with one channel's speaker wires or speakers. Connecting them one by one and retesting should allow you to find the problem speaker or connection.
If after checking all your connections, the Protection indicator stays lit, you may need to "initialize the microprocessor (see the FAQ on that topic) or take your receiver to an authorized repair center for a diagnostic. The "Initialization of the Microprocessor" or "reset" procedure can be found in your owner's manual on current model AVR product. Please note, this will erase all setup configurations in the system and require the system to be setup again. You may want to mark down the settings before resetting your receiver to aid in the setup process. If you had an installer setup your system, you can contact them for assistance and any associated costs that may apply to setup the receiver again would be the responsibility of the owner.

Sony dab fc7 wont power on


Two thing here.
#one the internal fuse has blown unlikely as the standby light is powered.
Two the power supply unit or switch is faulty.

get some one electrical component with the unit unpluged open the case and check any internal fuses have not blown.
Two check capacities on the power board these are large cylindrical shaped objects. These can dry out and or exploded if faulty relatively cheap to replace.
Second check the power switch actual powers the unit again someone with a multi meter and electrical compertent.
It is probably worth replacing either a capacity or switch anything else may prove false economy
I have replaced power board on other units but to be honest unless the unit was very expensive I would buy new

My RCA Model RTD325W On/Standby light is red but will not turn on, what do I do?


I have had the same thing happen. Unplug the unit (AC) and wait about 30 seconds. Plug it back in and it should be fine. I assume you tried both the remote and the front panel controls.

Flashing standby and disc wont eject


Try this: Turn it off and unplug everything from the wall and the device. Then hold in the on/off button for at least sixty seconds. Replug and try it. No guarantees but worth a try to reset the device.

No Power From My Reciever


Mook_trakzz, your device is most likely roasted and ready or scrap. Sorry.

Guest, check if the cables are connected properly, specially the cable between the device and the sub is quite easily shifted thus losing your sound.

timtlc, seems you have had some powerfailure during that night, you can try to remove the powercable for at least 15 seconds, that should reset the device.

to all, information from Philips on this device:
  • Press the STANDBY ON button on the front of the DVD system to turn on the power.
    If the device powers on at the unit and not the remote, the unit may have been turned off with TV selected as the source on the remote. The standby button on the remote will operate most Philips TV’s when TV is selected as the source. Change the source to disc or any other source than TV on the remote.
  • To completely reset the player, unplug the AC cord from the AC outlet for 15 seconds.

Onkyo HT-SR800 won't turn on


If you call Onkyo directly, 201-785-2600, there is a procedure to "reset" the system, something like holding the power button on and holding down another button for a few seconds. Can't remember which, so I can't be sure, but try giving them a call.

Hello, imho you must initialize your jvc.
Follow the instructions:

(2) Insert power plug into outlet while pressing both "PLAY" key and "STANDBY/ON" key of the main body.
"Area code" is indicated at the upper left of display.
(3) Press "PAUSE" key of the main body.
(4) When initialization is completed, "00" and "RDS" is displayed in the FL display.
(5) To release test mode, press "STANDBY/ON" key of the main body.
(6) Now unplug the power plug an insert it again after a 5 seconds.

Be carefully and press no other key then the list above.

Now it will be work fine again.
I hope it would be helpfully.

Unit stays on standby


The only thing I can find in the manual (link below) is to remove the power cord for a few minutes & try powering on from the "Standby ON" button, also set the "source" to anything other than TV. http://www.p4c.philips.com/files/l/lx3600d_25/lx3600d_25_dfu_eng.pdf
