Hello all!

I have recently bought a technics SH-GE90 equalizer and it has a fault: flashing screen and loss of memory when power cycled off and on.

Anyone know how to fix this? Anyone know where I can get a circuit diagram for this?

Thanks in advance....

Hello everybody,
I had this problem on my GE90 and I found, that the electrolytic condenser C715 (100uF/35V) in power supply (its on the mainboard near the input from transformator) was bad. It should stabilize a negative voltage for display and when it doesn't, 50Hz from mains supply interferers with refresh frequency for display and this is why it flashes. It was my solution, I hope that it helps somebody
good luck Very Happy

I had the same problem, and then replacing the elco C715 solved the bug. It took 15 mins, and $0,1.
