HDMI light is flashing


The unit is in protect mode. Try pressing and holding the 'advanced surround' and power buttons. It should power up. If it shuts down again right away, there is a problem with the amp that needs to be repaired.

Can't open,in protect mode


Hi:
First disconnect all speakers from the unit and then try turning the unit on too see if it still goes to protect mode. Protect mode is a shut down feature that shuts down the unit because of a shorted speaker or speaker wires are touching each other. If the unit does not shut down after disconnecting all speakers then reconnect them one at a time while turing the unit on after each conncection until you find the shorted speaker. If it shuts down with no speakers attached to it then you have a internal problem with the amplifier section, probably a shorted output transistor in the Amp circuit or preamp circuit.

The protect indication is due to a overload on the power amplifier unit. So you need to check the speakers to see that they are not shorted. remove all the speaker lines and switch on.
if there is a processor reset, power off the set and switch on while holding the selector/standy by switch. if not there is damage in the output within the amplifier.

My Onkyo TX-SR500 receiver stays in standy/on mode.


It may be your amplifier protection circuitry is being activated and shutting down automatically. This is usually caused by a faulty output transistor in one or more of the channels. I recently repaired my Onkyo TX-SR500 which had this problem.
Using a multimeter on ohms check between C and E on each of the ten output transistors. I found Q6051 and Q6061 to be short cct on all pins. Once you have located the faulty channels check the adjacent components for open or short cct.

I replaced the following components,
Q6051 (2SD1047)
Q6061 (2SB817)
R6091 (2.2ohm fusible)
R6081 (2.2ohm fusible)
R6101 2x 0.22ohm 2W
Q6031 (2SD2061)

The amplifier now works perfectly, cost of the parts is about $15-$20.
If you don't feel confident doing this yourself just find a friend or tech who can do it for you.

The unit is in protect mode. A problem was detected in the final stage of the amp and the unit shuts down to prevent further damage to either the amp or speakers. Check the speaker wires to be sure that they are not crossed anywhere. If with the sepaker wires disconnected, the amp still enters protect mode, the problem is internal to the amp. This is usually defective output transistors. Expect a parts cost between $15-$40.

Unit is in standy mode. If it will not turn on, it might have a problem in standby circuit. If this circuit will not engage, the unit will not power up. Take unit for repair
