SOURCE: stand by button flashes but receiver wont turn on

I have vsx-d812 that has an AMP ERR in error menu. the troubleshooting was found to be Q696 and Q697 in the DC prot. area on "C" board, up near front toward diplay in center of c board. You can get access to error codes on VSX pioneer unit by pressing "enter" and "adv. surr." simultaneously for 2 sec. The display should show what error code you are experiencing. I believe there are three diff. error codes. 1) AMP ERR 2) OVERLOAD 3) BOAD ERR (not mistyped) I hope this helps pinpoint error code for ya.

SOURCE: Receiver keeps flashing "PROTECT"

The protect message indicates that a problem was detected in the last stage of the amplifier and that it has shutdown to prevent further damage. Usually this indicates that the output transistors have failed. Any shop that works on audio should be able to repair this. Expect a part cost in the $20-$40 range. Add in the local labor rate for the total repair cost.

SOURCE: Protector flashing

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

I have a Sansui 2000A Stereo Tuner Amplifies that powers up but has no sound. the fuse for the 220-250V 2A was blown and replaced. The speaker fuses look good. Should I replace them too or is there...


If the fuse was blown on the 220-250 V side, I am assuming that you are in the UK, if you aren't , but are in the US, change the power setting dial/switch on the back to 100-120v and you might be good to go. Also, I know this may sound silly, but make sure that the speaker selector switch is pressed in or set to a speaker set ( A or B). Love the Sansui gear, have many complete systems myself!

MY SONY HBD-DZ810 HOME THEATER IS CONSTANTLY SHOWING PUSH POWER PROTECTOR


The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.

1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

You may also refer to the following link for additional troubleshooting steps.

It is not working


I'm sorry to hear your DISH Network 311 receiver is not working, in order to further assist you can you please provide me with additional information? For example, was it working and has suddenly stopped working? Does it power on, can you see a light on the front of the receiver? Is it plugged directly into a electrical outlet on the wall, or is it plugged into a power strip/surge protector? If it is plugged into a power strip/surge protector please attempt to bypass and try plugging the receiver directly into the electrical outlet. If you'd like you can post a response if you have additional information to provide or need further assistance. I hope this helps!

TV won't turn on when push power button red light flashes


You can unplug the tv for 1 minute and then plug it back in since you have a red light you know it is getting power, also don't plug it into a surge protector when trying this. If the tv still has a flashing red light a service center will need to repair the tv, replacing more than likely the power supply or small signal board.

Flahsing Red Light


Now what you have to do is look for a reset button on your mouse and your wireless mouse signal receiver.
When the receiver and mouse both are on press the reset button on both of them one by one.
This should solve the problem.

TV won't turn on


Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.

For example, 3 flashes, then 7 flashes = 37.


Here are the error codes, and the corresponding problem:

12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
