Hi..
Just got hold of a second BL7000 today, not in working condition right now..but it will be..
* Totally dead when off the charger
* In the charger the remote works, but it is in kind of a blinking mode with the red buttons when in std.by, the led's swithes on/off as if the mask is pressed constanty.
* The batteries measures 0v when unsoldered from the remote
* The charger is missing the 220k resistor(it is broken) between pin 2 and 3 on the connector to the BL7000, could this be the cause of the dead battery ? And would adding a new resistor make the battieries able to charge again?
* Missing backlight totally, will try to measure the voltage when i get charged(new) batteries in when charger is working, if this is ok, then replace with new backlight.
*According to the schematic of the charger,the charge voltage should be 6v, but both this broken one and my working one measures 9v ?
* The backup battey is dead, will replace with new one
* The newly acquired is a type 1540 but with a label that says "SW 2.1 RDS", can I switch the PCB board with the one in my working BL7000 and get my mint 1540 upgraded to RDS ? :) Are there differences on the display/button PCB's that might cause issues ?
* 2-way not working, last fix after everything is working again :)
Could someone measure the voltage on their charger to see what the voltage should be ?
And feel free to join in if you have any answers to some of my questions :)

Ok, status is...
* New backup battery
* Fixed 2-Way issue
* Fixed charger resistor
* With new batteries the remote now works like a charm..
* And it is the RDS version :)
Except for the backlight !!
The voltage to the backlight is 0V, no humming from transformer at all..
Any ideas ?
Final update on this complete overhaul of a mis-treated Beolink 7000...
Backlight is now working perfect, just needed a new BC817-25 transistor, and a 10nF capasitor :)
I will NEVER give up ;)
The remote is now working perfectly, the glass unfortunatelly has som dents on the corners, but it is working..
Congratulations Jacob, never give up!
