SOURCE: My Technics stereo system ...the display screen shows nothing

The question is, do you hear any sound? Is just the display off or is the entire unit shutdown? Can you tell?

These displays are known to develope poor solder connections at the power input and ground pins. If you can solder, open up the unit (unplugged of course) and examine the pins for the display. This will be on the PC board attached to the front panel. The pins at either end of a long line of pins will be the power and ground pins. Reasolder those pins, taking care not to short the pins together and try the unit once done. If that does not resolve the problem (assuming it is just a display problem), update this with as many details as you can about the behavior of the unit and we'll look further.

What are the functions of the impedance button on the Technics SA-AX730


This allows you to select the correct amplifier output impedance for the particular speakers you have connected, Proper selection insures the best efficiency, response and prevents potential damage to speakers or the amplifier, Refer to page 17 of this manual:

My technics sh-eh780 stereo seems to work but the sound is very dull in sound


Unless there's an issue with internal components of the amplifier or speakers, a common cause of this is reversed speaker polarity.

The wires between the + and - terminals of the speakers MUST connect to the same + and - terminals on the back of the stereo amplifier. The speaker wires that came with the stereo are color coded to help prevent mis-wiring. If you did not pay attention to this or used different wires for any reason, you need to ensure that the wires between the each of the speaker's 4 terminals connect to the correct group and + / - terminals on the amp.

See page 6 of the manual here: https://support.panasonic.co.nz/docstore/SC-EH780%20Operating%20Instructions.pdf

Make sure that the surround and center speakers are connected correctly, too.

Good luck!

Hi I just got a Technics SU V2 amp and can't get sound from the speakers. What size speakers would suit this amp? What is the correct method to connect the speaker leads to the back of this amp,...


Being a 500W amplifier, you need to connect speakers with 300W each. The correct method to connect speakers is red terminal of speaker should be connected to red terminal of amplifier & black to black. The left side to left side speaker & right to right speaker. There may be main & remote terminals. Main speakers are the speakers at local place of the amplifier & remote for remotely placed speakers. I do have Technics SU-V85A which is somewhat similar. Enjoy! A nice piece to listen.

TECHNICS SUPER BASS, DOUBLE BASS AND TRIPLE AMPLIFIER


Have you checked all circuit boards for good solder connections.
Also if the boards had been wet from anything, you might clean the boards and resolder all connections specially in the power supply and audio section.

Let me know.

Loose connection on "POWER-SUPPLY" and sometimes solder loose on "C I S BOARD" due to extreme - heat of amplifier. $137.51 repair done in 1HR as I waited at CENTURY SOUND ELECTRONICS.
