When the protect indicator comes on, usually a power transistor has blown. The unit needs to be taken to a repair shop.

Testimonial: "By a method of trial and error, I have solved the problem. I disconnected the CD Deck from the control circuit and the set started to function normal again. I'll now have to troubleshoot the deck itself to find the fault."

Sony hcd-ec99i i have no sound from the speakers at all. I am not getting the protect message. please help


Check the simple stuff first

Is it muted?

Is the source selected sending signal (radio staion broadcasting, cd playing, ipod all the way ect)

Try doing some basic troubleshooting like,

see if all sources available yield the same result (TV, Radio, CD, Ipod, Aux jack)

When you turn the volume all the way up, do you hear an audible hiss from the speakers?(or use a test tone) If so, your amp is working and the problem is, your unit is not sending any signal to it.

If possible hook up your speakers to another system to rule them out, however I doubt that is your problem.

Here is sony's recommendation and a review video

I have a Sony CD/tape player model # HCD-NE3. When trying to read a CD - it says NO DISC. What should I do?


Typically a no disc display indicated dust on the optical unit ( lens ) or failure due to low laser beam emission. For the first case you have to remove the top cover and clean the lens very gently with a ear bud. The the cleaning does not solve your problem you have to replace the optical unit itself. Unless you have experience doing the above i won't recommend it. Replacement will cost you about 15$ plus labor.

Pioneer vsx 515 overload and shuts down what can i do to fix this problem.


hi,
First of all remove all the speaker connections from the amplifier. After that power the amplifier and check the overload (protect) show or not . if not, then any of the speaker is damaged or you have to check the impedence of your receiver and speakers. It will be written on the rear side of both receiver and speakers in ohms. PIONEER recommend to connect 8 ohms speakers in to this AV receiver. If you are using 6 ohms speakers you have to do some setting in the AV receiver.For that do the following

1. With the receiver in standby, press STANDBY/ON while holding down the SPEAKER IMPEDANCE button.( Each time you do this, you switch between the impedance settings: )


SP 6 OHM - Use this setting if your speakers are rated at 6 Ohms

SP 8 OHM - Use this setting if your speakers are rated at 8 Ohms or more


You are not able to connect speakers with impedence bellow 6 Ohms with this receiver. Becuse the AV receivers impedence range is 6 - 16 Ohms.
If then also it shows protect you have to check the amplifiers hardware.

AV receivers shows protect mode , when there is a hardware fault in side it. Its a warning that some thing is wrong.
Normally AV receivers show this when any of the output amplifier get some problem. there are six amplifiers in this AV receiver. May occur when the output diver transistors of any of the amplifier become shorted. if the output transistor get shorted this will lead to flow of current through the speakers. To prevent this there is a protection circuit for each channels. One combined output of this protection circuit is connected to the system control. when the any of the output amplifier fails, the protection circuit detects it and switch of the speaker and sent data to the system control. when the system control get this data it will give a warning to the customer through display that PROTECT.
You have to check the amplifier.
for that you need digital multimeter,soledring iron screwdrivers etc
open the amplifier , then power it on. connect the negative terminal of the multimeter any where in the chase( metal body of the amplifer). then connect the positive terminal to all the output transistors emitter pin one by one . the voltage should be bellow 0.5V. If any of the emitter of the transistor shows voltage more than 0.5V., then that amplifier stage is faulty. Remove the transistors and check it. if it is shot then replace with a new one.
after replacing the transistors do not power up the amplifier directly from the main. You have to put a bulb of 60 watts in serial.
You can do this easily remove the mains fuse. put the bulb in a holder. now you have to wire from the holder. connect one of it to the one end of the fuse holder and the other wire to the other end of the fuse holder. Why using a bulb is, if there is any further problem in the amplifier stage on which the transistors replaced, there is a possibility of the new transistor get damage. if we use a bulb in serial with its mains supply ,when any overload in the amplifier occur the bulb will drop the current, by lighting itself.
After connecting the bulb in serious power on the amplifier. watch the bulb. It should light for one or two second and go dim . if so check the display, is there is protect mode is on or not . if not and come back to normal operation ,then remove the power , remove the bulb insert fuse and check
connect the power and check.
If the bulb shows bright light then there is some component also faulty in the same amplifier. after removing the power you have to check again the amplifier stage of which the transistor is replaced, for any other faulty components.
ok

Sony home theater model no hcd-dz570 push power protect error on display what,s solution?


Check the speaker connection. One of them has a shortcircuit. Try to disconect all of them and power on the device. See what is happen. If starts corectly check the speaker cable. Conect one by one and power up the receiver after each connection. When you get the error again check the last conected cable. These receivers have a protection system against shortcircuits. That is puting your device in that error.

Just bought refirb. Onkyo 805, hooked up front l&r plus sub and getting no sound. I set up am and fm as per manual and connected a cd changer thru the cd in via rca cables. Radio shows a signal but no...


After few sec when you turn on your receiver did you hear a click noise ? if yes your receiver is OK not in protection mode if no click noise is output protection in that case you must return where did you buy for service and update firmware a lot of update
However you can reset your receiver and debug the DSP section ( digital signal processor ) as follow
To reset
1. Press and hold down VCR/DVR button, then press STANDBY/ON button when the unit is Power on.
2. After " Clear " is displayed, the preset memory and each mode stored in the memory are initialized and will
return to the factory settings, and turn to Standby mode.
Now turn back on and check if it work or not and make sure check input mode such as analog or coaxial or optical input if stil no sound then debug DSP as follow
To set in DSP debug mode
1. Press and hold down DISPLAY button, then press STANDBY/ON button while the unit is powered ON.
The version number of m icroprocessor is displayed only for 3 seconds.
Main:
8 1.05/07903A
2. Press TONE+ button within 3 seconds above, the version number of 1st DSP is displayed.
DSP 1st:
SR8051:07601A
3. Press DISPLAY button while the 1st DSP version is displayed. The status of DSP and DIR will be displayed.
E1A48K0N/0FFPo
FFFFFF0 0 000
To exit
Press STANDBY/ON button.
Then unplug the unit for 30 sec then plug in it should work now if not you need to return it to 1 of the service center Onkyo in your town to repair it
Good luck
