Re: rt2300r problems

This receiver is infamous for loose connections inside of the unit due to corrosion, heat, cold or age. UNPLUG the unit from 120VAC, then open case. Disconnect and reconnect the connector from motherboard that goes to the thermister (heat sensor) on the big 120VAC transformer. It's right there on the top of the transformer, not hard to find. Then, disconnect and reconnect the smaller low power connectors which are located on the motherboard just to the right (if the front of the receiver is facing your belly) of the big 120VAC transformer. This may just fix your problem. Wiggling and disconnecting/connecting other connectors within this unit may cure a multitude of other symptoms, too...Just make sure and disconnect the unit from the mains and, as always, stay away from those large capacitors no matter what equipment you're messing with.

My onkyo HT RC330 will not power up at all. Have had problems past couple of months with starting it but if you played around with swith it would start. Now nothing.

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.

RCA Reciever no sound

You could have speaker wires shorted, putting unit in output shutdown. check them. Turn unit on and listen very closely for about 5-6 seconds for a click (the relay for okay output condition). If not heard, have unit serviced or check for blown output fuse. Of course they don't blow without a reason.

Why does it turn on automatically without any prompt?

Check the following.
(1) Is the power source a reliable connection ?
(2) Is the wire from wall outlet a good one ?
(3) Have you made a pre-set settings for playback ?
(4) See page 26 of the user manual on ' auto play'
(5) Try to change default source before you put on standby. Download manual

My rx 675 wont turn on. the red stand by light flashes and that is it.

Try holding the 'tone control' and 'info' buttons and pressing power. This should allow the unit to turn on. See what the front display says at that point. I tshould show some kind of protect code. If the unit turns on and stays on normally after that, then you may have had a temporary problem that was cleared by disconnecting everything. If it turns back off right away, then you will have to get it repaired as something internal has been damaged.

Sony dab fc7 wont power on

Two thing here.
#one the internal fuse has blown unlikely as the standby light is powered.
Two the power supply unit or switch is faulty.

get some one electrical component with the unit unpluged open the case and check any internal fuses have not blown.
Two check capacities on the power board these are large cylindrical shaped objects. These can dry out and or exploded if faulty relatively cheap to replace.
Second check the power switch actual powers the unit again someone with a multi meter and electrical compertent.
It is probably worth replacing either a capacity or switch anything else may prove false economy
I have replaced power board on other units but to be honest unless the unit was very expensive I would buy new

My ht303su wont turn on, its just not getting any power. i have tried multiple power sources and still nothing. not even a stand by light

Possible that the power system is damaged or that the safety fuse is blown. It is important that the set be opened to check this out to confirm. If so replace with the same rating.
Otherwise the power supply unit is faulty , check the transformer and the secondary stages.

Sounds to me like something burnt, maybe a fuse, Capacitor... Without opening it and running test it would be hard to determine the exact source of the issue. If you are using a power bar try it without.
