Hi folks,
For the very first time, my old FT-857D is
messing around.
When I push the Power ON/OFF to switch off the radio, the front
panel stop displaying the informations from the VFO but don't
switch off totally the radio. The LCD is still illuminated !
And switching on again don't bring the display back. The only
solution is to switch off the power supply.
The problem is I need sometimes to switch on/off again several
time the power supply to get the radio running again.
I think in no time, I won't be able to switch on again the radio

Any suggestion about what to check ?
Many thanks in advance,
73 de Thierry, F4GVO

? First, check the power supply voltage. And check when 857 is powered off and on. There should be virtually no difference in power supply voltage. ? ? ? Regards, Tony F. VA7TF? VE7ACF ?

When all else fails, try a hard reset! Remember though to have your settings in your program on your computer. ? 73 and good luck! Jim, N8JE ? Sent from for Windows ?

Thanks Tony,
Power supply is around 13.97 V and when 857
is powered ON, there is no difference (14.01 V).

Hi Alex,
Thanks for the tips.
as I use the speration kit YSK-857 in my
shack, the idea was to connect back the little RJ-45 cable to
the radio instead of the long one. After reading your message, I
disconnect the radio from the power supply and this morning it
is working perfectly !
I am relieve !

ALWAYS, call Yaesu Tech Support before doing any resets. It may be a simple problem that can be corrected without loosing all your data you have storied in the radio. Its a free service.
