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.

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?

It is not possible for us to be able to determine the extent of the damage. It is possible that only the fuse has been damaged. It is also possible that the rectifiers have been dmaged. The bottom line here is that there needs to be some examination of the unit and some testing of the internal components. The best case will use parts in the $5 range. Worst case you are looking at $50 or more in parts. If the cost is not too high, take this to a servicer and ask for a detailed repair estimate.

Good day...My unit works 100%...i just wanna know why the two vertical red lines on the display flashes. Never did it before. Any reason for this ?


The 2 larger power supply capacitors need replacing.
These are prone to leaking on this particular model and cause
the display to flicker.
Depending on how bad the leakage, if you take the lid off you
may see evidence of this around where the power transformer lead
plugs into the main PCB.

MY technics SH-DV290 AMPLIFIER is always in demo mode any ideas about turning it off.


Turning DEMO off
A demonstration of the display is shown if you have not set the clock.
You can reduce the power consumed in standby mode by turning the demonstration off.
While the unit is on:
Press and hold [-DEMO] until "NO DEMO" is
displayed.
Each time you press and hold the button:
NO DEMO (off)9DEMO (on)

The 'Demo' button is on the left hand side of the front panel.

I will be upgrading my av receiver soon. The latest editions seem to have an in-house equalizer feature. Should I still use my Technics equalizer, which will give greater benefit ??


If you use the amp for music most of the time I would certainly keep the older eq as I am assuming it is most likely a good quality analog device.

These modern ones are almost all digital and are not as nice or easy to use and probably introduce latency to the signal path. Sound is all about what you like and I would bet that you will prefer the older analog sound over the new digital version.

I am not sure exactly how this would affect the other uses of the new kit such as cinema etc.

Hope this helps Thanks for using FixYa.

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
