I finished the Beogram CD 5500 today.

Since I was not sure if I could save the drive suspension and the drawer mechanics at all I did not directly order new suspensions from Martin. Instead I cut replacement hangers from a thick old and soft leather belt.

This worked much better than I expected. I then had to build a new mount for the small PCB under the drive for the flex lines and (for whatever reason) at least deburr additionally drilled holes. Now everything works fine again. Visually, the device after cleaning with Isoprob is a real feast for the eyes.

There is only one small downer, the CDM drive that works has no magnetic spindle. the CDs are therefore not properly clamped and slip a little bit when starting. But it still works.
Does anyone know if and if how to change the spindle in the drives?

Nice work. Really clean 4k you have there! I can’t wait to work through my BM4k. I have a BG4002 with CD4 built in and can’t wait to get the duo playing together one day.

Thanks! Don’t forget to post pictures when you get your duo working. I hope someday to have the same combo but am still waiting for the right turntable to come along. Glitch

Evan: Hopefully this will provide you with some motivation to get your duo working ;-) Glitch

Beomaster 5000. I'm shocked it worked, given how many bad caps it seems to have. It did not sound good though. Login to view image Login to view image

I bought a 'spares or repair' Beo4 on eBay and the only fault was a damaged screen - it displayed fine but had damage in the corner. Despite arriving loose in a jiffy bag, I was surprised how 'new' the Beo4 felt on arrival, with a nice positive click when pressing buttons.

On opening to replace the screen I noticed the test date on the chip - if I am interpreting it correctly it's only 6 months old! Also 'Teszt' is Hungarian for 'Test' - is that where they are now made?

Picture below also shows the damaged screen and the 5.5mm socket that I keep in my desk draw so I don't have to keep going out to the garage to get my socket set when fixing remotes!

I am not really sure about the cost effectiveness of such repairs:  The Beo4 was about £20 incl P&P, a new screen about £25 and a new battery cover £4.  In the past I have bought equally nice condition Beo4s for much less than £50, even a V.AUX version.  Never mind, there's a certain satisfaction in such a simple repair!

Wouldn’t it be possible to repair the screen? I don’t remember well how they’re made and what cause the leaking, but if it can be removed and the glass repaired, that would made a better remote that one with a missing line of pixel or very dimmed digits.

Looks like thin sheets of glass sandwiches together. I can peel the silver foil off the back and it seems that the rear sheet of glass is broken - this must have taken the shock when it was dropped or whatever.

I do have a tatty Beo4 (with lines missing from the display) on my desk (to answer random questions on Beoworld!), so I will probably fit in into that so that I can read the text more easily. If I can find some shiny black material I may blank off the area above and below the text to hide the damage.

LCD leakage is starting to spread between the glass sheets now anyway - time to give up and open a beer! ??

Too bad! Thank you for looking.
(It would be nice and useful to launch a thread on these Beo4 screen fault and find solution! I still dont understand when the fault is before or after the gummy band…).

Enjoy the beer!

I just got hold of a pair of remotes, both listed as 'spares or repair.

I have spent the last couple of hours stripping them down, removing the dirt and grease and re-assembling.  As expected (hoped?) they both work perfectly, but I thought I'd post 'before and after photos' for those who want to zoom in and see the grime.  Rest assured that the inside was far worse than the outside, and took quite a bit of hot water and scrubbing to remove the grease!

As you can see they clean up quite well as long as you are careful not to damage the rubber keyboards.  The trick is to remove/assemble when they are warm, and a hairdryer may help.  There was a bit of battery acid in the Video Terminal but a little dab of vinegar dissolved this.

The Video Terminal is interesting.  Initially I tried to test the AUX and TAPE button with my BeoSound 1, but then realised that it will only control video equipment, hence AUX is actually V.AUX (or DTV2) and TAPE is V.TAPE (or V.MEM).  I also discovered from an old thread that PRINT sends the PC command.

Anyway it will go nicely with my Audio Terminal in a future setup.
