The manual states (apologies if you have the manual and are already aware of this):-

The indicator should flash for about 5 seconds then stay on steady.
If it continues to flash then the following may be the cause:-

DC voltage appearing in the output.
A short circuit in the speaker wires (or speakers)

(Manual doesn't specify whether speaker open circuit would give this fault. Perhaps try another set of speakers?)


I would add that this might be too low an impedance speaker or incorrect setting of impedance (see the button on the back of the unit). If in doubt set to lowest impedance then if speakers are higher it shouldn't cause harm.

Su-2760 will not work. gets a flash of power, turn off


Sounds like the safety circuit is tripping cutting off the power. Most probable cause a short circuit on the main power amp board, causing an overload.

Hello! I have a problem with Technics SU-V2X


Well whatever is playing up sounds like it might be getting too hot to me. In any case it's something common to both channels. Just have a look on the heatsink to see if it uses a single IC for both channels, they are can cause lots of problems!
The IC might be marked STK with numbers after the letters. That is the part number too for ordering a new one.

Technics su-Z750 Intergrated Amplifier stays in Standby


HI...
This happens when one or more components in the power amplifier section has failed.

The protect circuit keeps large DC voltages off the speakers.

The only thing you can check for before finding a tech is that the speakers are firmly connected at both ends. If they are ok, you need a tech

Technics SU-G91 OVERLOAD PROBLEM


THe amp has detected a problem and shutdown to prevent further damage. This unit has 2 amp pacs inside and one or both have failed. If you can solder, you can fix this yourself. The main amp pac is an SVI3206 and can be purchased online for about $60.

Keep me posted.
