Either the power switch is shorting out, or you could have a faulty or somewhat faulty resistor or capacitor on the power board. You can test them with an anlalog meter. Each component has an imprinted number on it to determine it voltage and ohm rating. That number should match the number on your tester.
Some units also have relays in them. The little square plastic boxes. You can test these with an ohmmeter but you would likely have to pull the circuit board to test the relay from the solder joints on the bottom.

Works fine but the fan runs constantly from power on its a yamaha z9


Some systems are just designed like that, especially chinese cheapies. I have an ESC I bought from china and the fan stays on the entire time its turned on, its just to say a few cents not installing a temp sensor and automatic switch.

Yamaha DSP-A3090: All video settings trip unit and it turns off


Hi...
Is the first set "stereo" settings and the 2nd set "surround" settings?
If so that may mean that the surround speakers arent all connected right.

I cannot get the functions on the remote to operate.ie pbass dsp/eq etc?


The P.BASS function is only available with 2 channel LPCM sources such as mp3,Divx,cd
and wma. Press P.BASS button and "POWER BASS ON" will be displayed on the screen.
The P.bass does not work with DSP/EQ or DOLBY PRO LOGIC ll modes.
If you press P.BASS in the DSP/EQ mode, the DSP/EQ mode is automatically shut off and the P. BASS function comes on.
The DSP/EQ function is only available in STEREO mode.
Press the PL ii mode button to show STEREO on the display.
This feature works with CDs, MP3-CDs, 2 channel DVD-Audio, DivX and Dolby Digital discs.
When playing a DVD disc encoded with two or more channels, multi-channel mode will be selected automatically and DSP/EQ function does not work.

Yamaha DSP A-1000 input selector switch not working properly


As that unit is well over 5+ years old, I seriously doubt the part is available any longer. I doubt that you will even find a used part, and even if you do, it will probably be as bad as your switch. As I have worked on audio for over40 years, I would use LPS 2. It is a lubricant. Do not try this with WD40 or similar. Just spray the LPS on the wafers, or through any open holes in the switch. You just need a little. If you just squeeze the button, you will see just a little bit of foam. That is all you need. No more; no less. Rotate the switch from from left to right and back again multiple times. Try that. BTW, no manufacture uses these mechanical switches any more.The controls are now called Rotary Encoders, which basically are inputs to a display microprocessor IC(a computer within the new product) which in turn controls the inputs of a switching IC. It's the same as your old switch, just electronic, and much more complicated. If you need more information, or would like to inquire about repairing your unit, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

2. Press and hold VIDEO 1 button.

3. While pressing VIDEO 1, press Speaker A button.

4. You should see "CLEAR" on the display for a second and it will go on stand-by mode.

5. Turn on the unit and check if sound is back.

Hope this helps
