20 Most Recent Technics SA-AX730 Receiver Questions & Answers

Records are binaural only. There are only two channels of information, left and right. There is no signal available for a center channel. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/dave_fb2c45146b845cea

I assume the Panasonic is a TV. I have never heard of green audio outputs. Audio outputs should be red and white (for RCA plugs). There are adapters available that convert the yellow, red and white component outputs to HDMI. You can get them at GameStop (I bought one recently to connect a game system for my daughter). If you have a TV converter box from your cable or satellite provider you might be able to connect the audio out on the cable box to your Technics receiver and run a HDMI to the TV (be sure to turn off the TV's internal speakers through the TV's menu) for video.

EVERY TIME I TUEN ON MY RECEIVER IT STAYS IN THE STANBY LIGHT AND IT DNT ALLOW ME TO LISTEN TO MUSIC

You know most of this....

What about heat and shorted speakers?

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Your speakers are way tp powerful you should only use speakers just over what the amp is rated at the most and check your impedance is not lower then 6 ohms and turn the bass to half way i am using 60 watt bookcase psb speakers and they work just fine and they pound no problem

See the link below for an explanation of protect mode. Specific to your model, there are 3 output amp pacs, any of which can cause this. Further investigation inside the unit is required to determine which one or more is defective. On rare occassions, I have seen bad voltage regulators cause this as well. Again inernal investigation will be required.

Hope this helps a bit,

its the orange input on the back of the amp left side of it from the fan says coaxial either above the input or below im not 100% if that will work for you i would suggest you use rca cable.

are u sure the fan is not working because on my ax730 the fan will only come on if im booting over half volume

You can't do it yourself only a good technician or repair center.I don't know the fix it cost.

the guide have the fuse you need an looking for !

It does sound like overheating. I think it might be worth opening up and blowing out the dust since that alone could fix it.

This is similar to protect mode in that the amp has detected a short in the output and has shutdown to prevent damage. Without seeing the unit, I'm a bit hesatant to suggest repair tips. At this point, I would suggest you get a detailed estimate from a local shop. We should be able to guide you through the actual repair once the results are posted here.

You most likely have either bad connections from the jacks to the main PC board or the video switching chip has an internal problem. Try resoldering all of the input jacks first and update this with your results.
