Ht-rc330 hdmi board defective - Onkyo Ht-rc330 5.1-channel Home Theater Receiver

It sounds like you have an issue with the Anynet+ (HDMI-CEC) function. When the home theater system is connected to a compatible TV by an HDMI cable, you can sync the operations when this is enabled on both the TV and the home theater system.

You need to be turn the feature off on one or both devices. If you have another HDMI port on the TV, you could move the HDMI cable to that port. (Most TVs only have one HDMI-CEC enabled port.) Note: this turns off the audio return channel option. If you only have the HDMI cable connected between the TV and the HT-EM53C, you will need to connect another cable. Depending on the TV, this could be an optical audio cable, analog RCA audio cable or headphone (3.5mm) to RCA audio cable.

The manual for the Samsung HT-EM53C is available at ManualsLib here: https://www.manualslib.com/manual/355628/Samsung-Ht-Em53c.html .

A summary of the Anynet+ feature is here: https://www.manualslib.com/manual/355628/Samsung-Ht-Em53c.html?page=29#manual . Accessing and navigating the Settings menu is discussed here: https://www.manualslib.com/manual/355628/Samsung-Ht-Em53c.html?page=25#manual . Press the Home button on the remote and go to the icon with the gear.

I hope this helps.

Try resetting the AV receiver To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press 8 ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter Standby mode.

It is possible that the protection circuitry has been activated. Remove the power cord from the wall.. Disconnect all speaker cables and input sources, and then leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect only the power cord and set the volume to maximum. If the AV receiver stays on, set then the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your dealer.

If the standby light is lit it and the unit will not boot it is most likely that the protection circuit has been activated. If there is no standby light then check the fuses. These units check that the power supplies are operating near specification. If a capacitor or resistor in the circuit, or a broken solder connection the unit will shut down. Because of the temperature the thermal cycling around the power supplies a broken solder joint can occur. This will make for an intermittent operation.

Hope this helps.
Failed resistor or capacitor

Hello Billy, I would advise to try a factory reset of the unit. After the reset see if you are getting test tones out of your speakers in the level calibration menu. If you are not then the receiver would have to go in for service. Thanks, FJD

Unwire the receiver completely. Then rewire, ensuring that the speakers wires are correct. Make sure that the main power cord is properly connected. If problem persists, upgrade to new (and better) receiver.
