Sharp DR470 - Service mode

Rate this topic

4 posts in this topic

Hi all,

A while ago, I entered the service mode on my Sharp DR470 (called DR7 in some regions), messed around with it and now I am only getting an Er-MD80 error when trying to turn the unit on.

Somebody with a DR470 kindly agreed to check what the original settings were, so I can reset them, but I forgot how to actually get into service mode on this MD portable. I seem to remember that I had to use a remote control from a different unit (my MT831), but I tried it this morning and the DR470 just wouldn't react to anything that I press on the MT831's remote, so maybe I remember that wrong.

Does anybody now how to enter the service mode on Sharp portables that don't have a 'Sync/Enter' button?

Any help would be greatly appreciated! Thanks!

I wonder if you can find out Service manual of the same, which can help you enter service mode of this model .

I tried Google, but had no success. I found the service manual for the MT877, and DR420, but the way described there did not seem to work for the DR470.

When I get home, I will try if the remote control works on the MT831, maybe the remote is broken?

Does the Sharp have a hold switch on the remote? The Sony remotes are entirely disabled if HOLD is set to on.
