THE INSTRUCTION MANUEL STATES THE UNIT HAS ACTIVATED THE AMPLIFIER CIRCUIRTY PROTECTOR ! DOES ANYONE KNOW WHY THIS MIGHT HAVE HAPPENED AND HOW CAN I FIX IT ? THERE IS A CD STILL INSIDE THE UNIT WAS SETTING IT UP AFTER HAVING THE UNIT IN STORAGE FOR 2 YEARS.

Re: ONKYO DR 90 STANDBY LIGHT FLASHES UNIT WONT START
if protector activated its means there is shorted speaker connected to your amplifier,try to remove all speaker and turn on your amplifier,then make sure your amp volume is in low position.if the protector is de-activated its means one of your speaker is shorted.then try to find out

Had an Onkyo DV-SP301 that would only intermittently come out of standby. Found faulty resistor R2 on the power supply board (board ORTP-865), it was nominally 5600 ohms, measured much higher. This after checking most p/s caps! R2 runs warm when unit is in standby, so you may want to replace with a higher power rated resistor. I used same rating but 10 k ohm instead, worked fine then.
test the capacitor with a meter to make sure it has the value stated on it. the work on this unit is quickly exceeding its present value, most likely. consider upgrading to a higher resolution unit if the fix is more expensive in parts and time than a new unit costs. good luck mark
Hello, This unit has a standby button, could that be selected -IF not, I am not sure what is causing the problem you describe however you can find the product manual here - http://www.memcorpinc.com/html/product_detail.php?PID=43&FID=9&SID=2&opento=1008#

Bad caps in the power supply is causing this. C17 (10v,470uf), C17,c14 (10v,1000uf) and C18 (10v,470uf). Replace with same capacitance values but 25 volt rating 85 C. Just fixed mine half hour ago works great.
Same problem on my JVC DR-DX5SU. Says "loading..." and will not respond. Factory solution is to quickly unplug and plug / or unplug for several hours and plug-in. I suspect that is to cold start and clear error flags. Did not work for me. I looked at the power supply board (immediately behind the DVD drive, on top of the hard disk). I noticed one capacitor was "bulging" on the top. See photo. Electrolytic caps should never be bulging - if anything, the top should be slightly concave.Cap was SAMXON 1500uF,10V,1400mA ripple - I suspect either voltage or current ripple spikes were exceeding its capability. Replaced it with a Panasonic EEUFR1C182 (Mouser.com), 1800uF, 16v, 2470 ripple current, to give it extra margin. Runs correctly now.
Onkyo units as well as several other manufacturers have a common problem where the spindle motor gets intermittant or wont come up to speed.Its not hard to replace this motor, but could be a trick to adjust the platter height. Also the unit probably needs a servo alighnment as well. This unit could also have a simple problem as a dirty laser lens. You can try to use a disc lens cleaner to see if that helps. Good Luck
