The screen keeps flashing rear chk and the rear speakers are not making any sound.


I had the very same problem, and found that if you power up the receiver in DVD/CD mode, or tap the function button to display DVD/CB mode, the Wireless Rear Speaker AMP will automatically recognize and turn on the sound. This work around was not posted anywhere in the manual, just 1 of many workarounds I have had to put up with this system to work. Right now my fan went and it just keeps shutting down, I have had this system for about 15 months and very disappointed with the quality. My DVD player stopped working a few months ago, so now the system is rendered useless, not even sure it is worth fixing at this point since it is no longer under warrenty.

DVD system shuts down during DVD play with various parts of shows


I think this is the answer you are looking for.

Let me know if you need more help.

Knowledge Article C337191 Error: The message PROTECT or UNPLUG shows in the display.
Follow this procedure to troubleshoot when a PROTECT or UNPLUG error is displayed.
IMPORTANT: The top of the receiver must have proper ventilation to keep from over heating.
  1. Reduce the volume level.
  2. NOTE: If the receiver is played at the maximum volume level it may enter the PROTECT mode. Maximum volume listening will cause the receiver to run hot and drain the output capacitors.
  3. If both the A and B speakers are being powered by the receiver at the same time, turn off the surround sound option.
  4. If protect occurs only when using a DVD player, the sampling frequency may be set too high.
  5. NOTE: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the user manual for specific information.
  6. Ensure the speaker wiring is not damaged and is properley connected to the back of the receiver and speakers.
  7. If the issue is still unresolved after completing all of the troubleshooting steps, service may be required.

A common cause are failures in the amplifier output stage, the drivers, and some of the support components. You will have to send the unit out for service.

Unit shuts itself off after 10 -15 minutes


Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Regards.

Protection Error when switching on SD-43HK


You will need to get a service manual and trouble shoot what amp. circuit is defective. if you have no solid state printed circuit board experience, you really should take this unit in to a repair shop and have it estimated. There is no quick fix for this unit. Good Luck.
