Question about Technics SH-GE90 Home Equalizer
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.

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.
