So I currently own a BeoLink 7000 and I am having a problem on Step 5.

When I  test it to see it's voltage, nothing happens. [Image in the link below]

I noticed that you ordered some parts from Conrad, but they don't ship to America so I am stuck with nothing to do.

Can you suggest an alternative location I can order the capacitors from?

I have also tested my electrolumiscent film and it is working fine.

The same wires that are connected in Step 5 seem to have a short circuit, but the wires are not tangled up. [Image in the link below]

I was wondering what could be the problem for that and if there was a solution for it.

Are you measuring alternating voltage at the backlight ? The voltage for backlight is approx. 110-130v AC, not DC.

Did the backlight work before you disassembled it, or was it completely dead ? I had one with a faulty SMD transistor that caused the backlight to not turn on. Also make sure that the flat cable on the back of the mirror cable, is attached correctly in the holder. Try to unlock it, and take it out and put it back in. This can also cause backlight to not turn on.

Regarding the "short circuit" this is not a short, it is just that you are measuring the connection between the AC transformer that provides the 110v AC.

Thank you for the quick response Jacob.

I am in need of this device working so hopefully you will be able to help me with fixing my problem.

I have measured the backliight with both AC and DC and neither have seemed to work out.

The backlight did not work on the device previously, but when I plug it into a 110v AC directly, I can see the backlight working.

I'm not sure what a "SMD transistor" so, it is possible you can specify what part of the device that is, and explain what it does?

I have dismantled every cable on my BeoLink 7000 and have plugged them back in, so I do not believe that this was the problem.

Thank you for clarifying that it was not a short circuit.

I had plugged in the 6v battery into the transformer and there seemed to be no reaction when I tested it.

I figured that either the transformer or the capacitors on the device are not functioning properly, is there any insight you can give me to this problem?

Is there a way to test if the transformer [in the picture below] is functioning properly?

Also, is it possible that you are able to give me the specifications of the transformer?

There seems to be no writings on the device itself to tell me what kind of transformer it is.

Thank you for taking the time to help me with this.

Hi james..

http://archivedforum2.beoworld.org/forums/p/11818/103230.aspx#103230

Here is some information on the transistor and capacitor I have changed in mine where the backlight was completely dead.

You can see in the schematic that the TR37(transistor) is a BC817-25v and the C15(Cap) is a 10nF, I used 50v for that 

I don't think the issue is the transformer, as it seems you have the exact same problem as mine.

Me too 😐

Thanks

Hello Bo and thank you for your shopping list.

However, I notice that beyopdn the LCD backlight film you have placed an order for 8 capacitators but I understand the BeoLink 7000 recapping only needs 5? (2 being SMD).

I haven't opened mine yet so not sure which I need for recapping to resolve the "no contact" issue.

Could you please help me as to which from the shoppign list I need. Perhaps all of them but where do the remaining 3 capacitators go?

Kind regards, BeoMedia

Hi,

I have two of these and opened one a year ago to replace the backlight, it has since been sitting like that but given this very helpful write-up, I will give it a go. 

My real question when I opened it had to do with this connection. Reading the above, I understand the lining up of the pins part, of course, but I am still a bit confused about how one can assure so many pins will ALL make contact! Is there any trick to it? It just seems to me that it would be very fortunate indeed if they did. I keep thinking whether I can use another method, like soldering thin wires, but appears a bit implausible.

I will appreciate.

A rather old, but yet very useful thread! However, the links for Conrad doesn´t work anymore and searching for the components brings up to many choices. Can someone with more knowledge than me put a "shopping list" together at Conrad for re-capping a Beolink 7000?

Never mind; I did find the correct parts at Conrad. When (at Conrad) going to the shopping basket, the partnumbers listed on page one can be entered and added directly; that worked.

Did you have any luck finding the backlight film?  Conrad Desoto ship to the US and the parts listed previously are all sold out.  Does anyone have any good sources?  I have a shop down the street that can do it I just have to tell them where we can get the parts.  

I just had a look on Conrad and if I’m looking at the right part (article number 1565919) it says it will be back in stock 17th June.
