Hi
I have a challenge for experts of these units & Co :)
I have a partially operating BS 9000 MK1When turning on the main switch, it sometimes goes to sST-by immediately and sometimes takes a few minutes. It's not definite and it's always different.When I turn on the CD, works normally with the original cd discs. In a minute or two I can transfer to other positions and unit also play recorded discs.When I turn on the radio, RADIO is displayed and the unit goes to st-by immediately.Sound on the powerlink output is only noise, even when the CD is turned on. there is strange sounds like I change songs and there is very quiet music regardless of the volume on unit dispaly .Digital output works normally.Moving between CD positions works normally.There is no errors to see in the test mode. ok..if cd not playoing or if i stop arm..there are roors..
It's not the first unit I had and repaired but I have not met such symptoms yet. Usually there were minor errors.
so..any help :)
The mk1 becomes more and more sensitive for errors due to the aging of the units.
The only solution is to overhaul complete pcb’s.
I changed the PCB tuner and everything is the same.I changed the masterlink PCB and it's the same.It probably can be a power board. What do you think ?
