Beomaster 8000 tuner problem

12 replies

Hello

I cam across a BM8000 with some problems.

Half of the led were dead but got them all working again (bad connection between board)

Remaining problem is this: TP1, TP2, PH works perfect. But the tuner is another story

I get noice ((like between two channel noice). Added to this noice: a "pulsing" noice that

seems to increase in frequency (pulsing) as I increase the fm-frequency (tuning)

 

The "vu-meter" is also pulsing. 

 

Anybody got an idea?

 

Best regards Lofke

Hi,

I don't know if it can be related but today, when I opened my unit, I forgot to put back the tuner plug from the microcomputer, which is well hidden under those ribbon cables. Could it be a bad connection there? The plug is shown here, under the green circle :

Hi,

Can you display frequency ? 

Hi Jaques, 

Yes the freq display is normal and bright as it should be.

When turning the freq dial it goes up and down as normal.

All i hear is static like it can’t find a radio freq.

then all of the sudden i hear a very short period ( say 3 seconds) radio ( freq 89,5)

 but that goed away and leaves me with static again. Tuning it further the same radio freq comes up somewhere else ( around freq 95,5 or so)

Thats also 3 seconds and goes away.

i can do the same over and over again.

 

Okay then.

I'd double-check every connector (remember there's one between the two tuner boards) and only then would consider something else.

And "something else" could mean opening the processor and memory can...

I was afraid you were going to say that, but thats what i am going to do.

checked and doubled checked every conector and connection between boards.

stil no signal. so i will have to open up that memory box and resolder and check everything inside.

Thank you Jaques!

Hi Jaques,

I fixed the tuner problem.

I replaced the prescaler inside the processor board.
