SOURCE: the dislay flickers SH GE90.technics .it seems to

replace the 3 electrolytic capacitors in the power supply section near where the lead from the transformer connects to.
they're sat side by side.
you may notice only 1 might be leaky but replace all 3 for good measure.

i've had quite a few with exactly the same fault and all were cured by replacing the above.

hope this helps?

Technics SH-GE90 DSP gives off high pitch sound, no display in the window,only the red dots down the side and the demo button dose not change demo modes.


Check power supply capacitors.
These are prone to leakage on the SH-GE90 and can cause various
symptoms such as no display or in some cases a flickering display.

I have a Technics Stereo graphic equalizer. Trying to find out why it's not getting any power. it has no fuse inside. I hook the plug into the outlet and nothing. atleast the light on the equalizer does...


The power supply unit has failed in your equaliser. If it is the main transformer check for the continuity of the primary and if open you will need to replace with the same one or rewind with the same parameter.However if the thermal fuse is blown you can short the winding with a fuse wire. Also check on the dc side for any fusible resistors that would have opened out. Hope you check this out. Good day

Having a hard time connecting various audio components


Yes, it is a little tricky...

1) CD Changer (output) -> CD input on Amp

this is tricky... this will allow you to record to your tape deck, and control the sound via the EQ:
2) Tape Deck (tape out / recout) -> TAPE PLAYBACK on EQ
3) Tape RecOut on EQ -> Tape 1 Playback on Amp
4) Amp Tape 1 RecOut -> Tape Deck Playback / Input / RecIn
in essence, your creating a loop starting from the tape deck, going to the eq, then to the amp, then back to the tape deck to record.

Your EQ has another set of LINE IN and LINE OUT - use the second Tape 2 on the amp to create another loop. This will
allow you to control the EQ for any of the other sources.
5) LINE IN on EQ -> Tape 2 RecOut
6) Tape 2 Playback on Amp -> LINE OUT on EQ

5) Radio Tuner (output) -> Tuner input on Amp
6) DVD/VCR Combo Output -> AV/AUX on Amp

7) PC Computer... you don't have room for this. You can either use the PHONO input, and you'll have to purchase a Line Level Phono Converter
or, get a Y cable and split the signal and share with some other source.

Hope this helps.
