Beomaster 8000 start-up & memory issues

[alf]

Hi All,

my BM 8000 has a couple of issues:

first the start-up:

when turning on the unit I have to hold down any source key (fm, tp1/2, ph) until the unit fires up.

we are talking about a US model which I operate with a step-down transformer and keep wondering

if the issue is cause by a lack of current, supplied by that step-down transformer and can a change of fuses

help here ??

second the fm pre-set memory loss:

after confirming the 5V supply voltage at 9IC6 is present I suspected a faulty IC, replaced that one with the same issue remaining ?

I can tune in fm station in auto and manual tuning mode and try the programming procedure but no luck,

it remains at 87.5 kHz.

what did I miss here ?

would be great if some of you could shed some light on those issues

thank you

Wow,

no one’s git a “light” ?
I was under the impression those issues are not that rare or are they ?

9IC6 could of course be a chinese counterfeit chip and with the supply voltage present

it would sound more  likely  unless the source of the memory loss is elsewhere.

com’on guys I am really struggling here
