The solution#1 answer is mine,it's happen i forgot to "sign in" thats why my rank is apprentice and guest.I will re write again here down so i get the rating.Try these test,the only common possibility would be the transformer and the power supply if both channels are out.You better to check both the positive and negative voltages from the power supply to see if both are present or if one or both are missing.This would be DC voltages of approx. 20 to 40 volts.The positive voltage must be equal to the negative voltage,with the exception of their polarity. The transformer can be checked for AC voltage before the power supply .This reciever uses a single power supply so the problem would be common to both channels.You better change the regulator and checked some capacitor near the regulator.

I have a technics SU-V98-KM8 Amplifier that turns on and lights up but does not have any soundd coming out of it. I have checked alll the cables and cords and everything is hooked up the way its supposed...


Your amplifier is turned on and all the indicator lights work and you made it sure that all the cables, and cords are attached to where they are supposed to be connected and yet you don't get any sound coming out when you play a music. Amplifiers have selector knobs for you to set where your source is coming from. Selector knobs can be set to TUNER, DVD, CD, and AUX. The scenario might be like this: your source is coming from a movie being played on your DVD player connected to your amplifier but your knob selector is set to AUX. Try playing a music selection from your CD player attached to your amplifier and set the selector knob to CD. If still there is no sound coming out you need to have it checked by a qualified technician.

Technics amplifier su-v98, cuts off at 22-24 desibls


The most common cause of this is defective coupling caps inside. These allow some DC voltage to pass through to the final amp stage. This DDC voltage is detected by the protection circuit and the unit shuts down. This unit will require service. Please note that this should be a simple and inexpensive repair. The cost should be less than $10 for parts.

Tecnics SU-G95 stereo overloaded


Power down,disconnect the speakers and power back up. If it still say's overload, it needs to go to service. If not, check your wires, connections, and speakers one by one to hunt down the problem and correct. Hope this helps

Technics SU-V98 No Sound


If I understand your posting correctly, the amp works using the Aux In connectors but not using the VCR1 even when VCR1 is selected correct? If that is the case, there is an internal electronic switching IC (TA9263 I think) that may be defective. This is not a complex repair and can be confirmed easily by any shop that does audio repair. They will trace the incoming signal with an oscilloscope to the IC and see nothing come out when VCR1 is selected. The IC costs less than $10.

Technics su-v98. Powers on but no sound can be heard, not even through the headphones jack.


Make sure it is not on mute. Check rear of receiver to make sure AUDIO IN has not become disconnected. Check input selector and verify that it matches the audio source.
