My Compact Disc Stereo System NSX-AJ50 is tripping
One or more of the output transistors has failed or you have a bad speaker. Try disconnecting both speakers and turning on the unit. If it still shuts down, then the transistors are likely to be defective. These can be replaced for about $15-$25 plus labor at any service shop that handles audio gear.

Hi: I have a aiwa nsx 800 mkII I hear left channel normal but the right channel sound very low ?qhere can I fix that?
Check first it is on all functions. If it is then it will be a power amp fault. As the unit has two channels both of which are identical to each other it's possible to check and compare each channel. So in your case the left hand channel parts are your guide to what is right. Compare first visually the two channels. If something looks burnt or damaged or wrong in the right, but it isn't in the left then you will have found the cause.
If everything looks OK, then carry out voltage tests, if you have a meter. Or a sound test. This involves touching with an insulated screwdriver the two channels while the unit is on. Never touch any part that there is only one of. Unless it's an IC and has two channels going in it. You will hear a buzz if it is working or produces sound. Again a good buzz in the left should happen in the same place as the right. When it's load at one point of a part but weak on the other, when it should be a loud buzz then you have found the faulty part.
Please however check first that it's not the headphone socket that is causing the problem. Sometimes the sound will be OK on headphones but not on the speakers. The socket the headphones fit into can cause this.

9VDC supply come from one of the LOT winding. If it should be there, the LOT should work. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts
