I sent my Beomaster 5000 for repair in California. This is the third time they have had it as they failed to repair the problems, in fact, they created more problems. The shop just sent me an email suggesting that this is not the same unit that they had serviced previously as the serial number sticker was missing and that the unit had a broken motherboard. The serial number and the shop's repair sticker was on the unit when I shipped it to them. I bought the unit new and this is the only time the cover had been off the unit. My questions to the forum:
1. Are there other location for the serial number to be imbedded in the unit?
2. What are the scenarios that a motherboard can be broken?
A motherboard is generally a circuit board accepting the insertion of optional/other circuit boards or modules. As in traditional desktop computers.Beomaster 5000 has no such circuit board.It has a tuner board, an amplifier/voltage regulator board, a preamplifier board and a processor board. All connected up using cables with plugs, - noneof them interconnects like in a PC.Which one are we talking about?
The Beomaster 5000 circuit boards don't usually break easily, even in transport - but of course it can happen.
There can be more serialnumber labels inside. Sometimes on the vertical dividers in front of and behind the processor module and/or at the inside of the chassis walls.
It wouldn't be the first time an owner was told something bogus, because the repairshop didn't know anything about the thing brought in.Believe me, we've heard a lot.
What was the problem/symptom?What did they do the first two times they had it?Did it work after that?Any chance they could provide photos of the broken board?

The initial problem was it just had a loud buzz when powered up. After it was returned, nothing would show up on the screen. After jolting the power system a few times by plugging it in and unplugging it, it came to life and worked reasonable well for a couple of weeks. Then it just would not show anything on the screen. Sent it back under warranty. It was returned with very weak volume in am/fm mode. Worked well in tape 1 with an iPod. Returned it and was informed that the technician suspected that it was a different unit than they had previously worked on. Said the motherboard was broken in right hand corner. Also said serial number had been removed, although the sticker with the serial number along with the repair shop sticker was on the unit when shipped. Was told two pictures were enclosed with the message, but they were not there. I bought this unit new in 1983 and this is the only time the case was cracked and by this repair shop which advertised they were an authorized B &O repair. After much concern about them, i reluctantly sent them the unit, as they assured me they could fix it. Looks like they did!
Hi BillHave a look at this old thread, with some nice pictures of the inside of a BM 5000 - and then ask the repair shop which one they call the "Motherboard"...

Dillon could you post me via my email, brledford@msn.com I recieved a reply with pictures of my Beomaster 5000. I have not figured out the method of posting attachments yet. Bill
Looking at the pictures that the shop sent, i think it is the tuner board that is cracked. It appears that it was pushed too close the the 0.01F filter cap and was broken at the screw attachment slot conner. The picture of the serial number sticker shows that it was ripped from left to right and removed the complete serial number. The rest of the sticker is in tact and in very nice shape.
It appears that this shop deliberately removed the serial number so thay could claim that it was not the same unit that they previously had worked on because they knowingly had broken the tuner board. They therefore can claim the unit is not under warranty and I would have to pay to fix it.
It is obvious from the picture that the board is jammed up to the filter cap and when they tighten the screw to hold the board it broke the corner. I do not see how it could break in this fashion from shipping or any other type of abuse.
I am still trying to figure how to translate some of the replies and learn how to post these pictures. Thanks for putting up with this novice.

I now can upload the pictures of the cracked tuner board and the torn serial number sticker.
If any body has any kind of input on how this could have happened to this unit, please respond. I am not going to let this shop get away with this.
That tuner board can be repaired using a little 2-comp. epoxy glue and a couple of leads - .. if a replacement board can't be found.Shouldn't give any good tech guy any problems. I have repaired boards that were considerably worse than that.
Is that a common problem with this board? Can you surmise how it might have been broken? I am sure it is not from shipping. That board is mounted with several screws and is well protected from outside influences.
When the unit was returned to me the second time, the unit had a very low volume in am/fm, but was much better in tape1 with an iPod, but still not anywhere near normal. Would this damage board effect that? If I could prove that, it would certainly indicate that the repair shop had responsibility for this failure when the unit was with them the second time. I also notice the serial number had been messed with when it was returned from the shop the second time.
It is easy for the shop to accuse me of switching units when they remove the serial number.
I am going to get all the evidence together that I can to force the shop to take responsibility for taking my money and not fixing the unit. It could in up in court, as I do not like be accused of fraud, when the shop is committing fraud themselves.
I have requested an itemized shop report on the repair the second time the unit was sent to the shop.
Thanks everybody for your help. I am negotiating this forum more easily now. It is a very beneficial forum with lots of knowledge from the members.
