Hello!
I know, it isn't easy, but i decided to buy a problematic BL7000, and try to repair it!
I make some progress, now the LCD is working, and no pixel errors so far!:)
The background lighting is still k.o. I measure the voltage between the brown and black wire, but it was 0V. Measure it also on the bottom circuit to ensure there is no defect wire, but it was also zero Volts.
How can i repair this problem?
Also it can happen, that the capacitor somewhere close to the IR diodes are also faulty. I read somewhere, that this can stop the two way communication. Wich ones should be replaced?
I can't see the volume value in the red LED dot matrix display. Also not the clock. I try to set it, but no success.
This group of display should work, sometimes i have two horizontal stripes instead of the volume value.
That's all, i think.:)
Thanks in advance for any help!:)
Charles
