Technics SU-G70 clicks on, but doesn't engage...

I turn on the amp (Technics SU-G70) and it clicks as though the power is turned on (and later you're able to return to feel that the amp is warm). However, the display is blank and there is no sound output. In the past, I could just slap the side and it would come on. After hitting it, the amp would either go back to blank after a few moments or it would stay on. It was hit-or-miss, no pun intended. Now, it seems no amount or strength of hitting will get it to come on. Please help. I have my first HDTV coming in a couple of days and I want to have at least something to hook-up. :-) Thanks.

I just got mine back from repair shop, same symtoms, they replaced power supply, in your case it was hit and miss for a while, so maybe bad power supply connections inside.

Technics Amplifier SU-V4


The clicking sound will be a relay for the protection circuit. That could be faulty, but first check out the main devices on the main amp section. Those attached to the big heat sink. If you see a single IC amp that could well be faulty.

When I turn on my technics SU-V55A amp, the current drive does not engage. If I leave it, it normally comes on after a period of time. The amp then runs ok.


Check for dry solder joints especially on the main power output transistor.
A blown power transistor will stop the 'Current Drive' from engaging so if the problem you have is intermittent then it is most likely dry solder joints.

Hope this helps.

Sir the problem of your unit is the power IC the other channel of this IC is already faulty. unplug the unit to the main AC outlet then remove the cover of your unit you will see a large aluminum plate the power IC is attach to that heat sink in order to fix this you should replace the IC. Or can you give me the part number of the IC so I can determine the pin configuration. Good day and best regards.
