Good Evening My Dad has a RCD M38 DAB Receiver He cannot pre set the channels could you please let me know if this receiver has n internal battery that would hold this information and it’s failed. I followed your channel to him. I would be grateful of any help. Many thanks Susan Morrell.
There is no backup battery in this unit, the channels - all settings in fact - are stored in an Electronically Erasable Programmable Read Only Memory (EEPROM) Integrated Circuit. I would suspect that the system has developed an error. The only way to clear this memory error is to unplug the unit from the mains for 1 hour then plug it back in and it should go into auto tune mode, once that is complete, you should be able to manually tune it in.
I think you've persuaded me that these newer all-in-ones are more trouble than they're worth. I like fixing stuff but I lack the patience (and arguably the expertise - that would have taken me quite a while to work out if at all!) to be bothered with that, for what is a modern device with all the inferior Chinesium goodness that implies. I admire anyone who gets the job done though!
Thanks for the compliment, I love doing repairs, ever since I was at school, it was a career I thought would last a lifetime but sadly, the newer cheaper stuff made doing repairs uneconomical and they are not really worth doing them, so I concentrate on older stack systems.
Hi, this is derived from the USB 5v line which is created from the DC 9V rail by IC43 (NR111E) on the USB to DC board. Page 52 of the service manual. Check for shorted connector pins on the USB socket.
Hey there I have a sony hcd lx30 it like the hcd xg500 but the problem is the push power and protector pop up and I can't listen to it anymore so is there any easy way for me to fix it
Thanks, if I needed one, I'd buy a used faulty unit from e-bay and strip it for parts. Sadly, I don't have any spares. You could always contact DENON Service support. www.denon.com/en-gb/contact-us.html
