I recently purchased a Philips DCC 730 deck and I noticed that side A of a digital cassette works fine and nothing is heard on side B. I mention that on analog cassettes it works perfectly on both sides A and B. It works well on digital only with original cassettes, with recorded cassettes it does not work on either side. What can I do, please, give you some advice? Thank you !
Hi and welcome,
Pretty common on the 730. Usually it means the pinch rollers are worn or the speed is to high/low. You can start by switching both Pinch rollers and see if it makes any difference.
Also try and play a regular analog tape to see on side B, if you think the speed is ok.

Thank you Mr. Ralph, I put new rollers and it does the same, the speed is good on the normal cassette, side A and side B work fine. When I put your cassette, side a works fine, I also entered the service menu and all 8 heads are 00000000 and aux 10, which I think is ok, on side b nothing is heard and I also get cleah head and sometimes error 26, but rarely. I wouldn’t want the head to be defective…
I also forgot to mention that even if nothing gets wet on side B, it still displays the name of the track…
I don’t think the head is the issue, as it plays side A perfectly. It rotates to do the same thing. Maybe the azimuth needs to be corrected? Does the head look at 180 degrees when playing side B? There could also be a mechanical defect, preventing the pinch roller to work normally, or a different mechanical failure.
The head rotates 180 degrees. I checked the azimuth with the normal cassette and it’s ok, and I think it doesn’t have any mechanical defects at the moment, on the analog cassette it works fine on both sides. And I don’t understand why it doesn’t work with cassettes recorded on another dcc, I also have a dcc 300 and a dcc rs-dc 10 and on both the cassettes I recorded work, only on this one they don’t work at all
Checking the azimuth with a normal cassette, is harder on any DCC deck in my opinion.
There has to be a mechanical reason for the “clean head” message on side B only.
I will check the mechanical part more carefully and I will keep you updated, maybe you can help me with some advice. Thank you
Take a prerecorded tape. In normal play mode, fast forward to the end and go back a minute or two. Power off and put the deck in service mode. Play to the end and let the player switch to side B and let it run.
What does the service mode tell you about the head errors when playing side B?
I wonder if many people know about this trick 
Thanks for the advice, I will do this today and let you know the result.
It might be a (little) misalignement of the head. Before you start adjusting, be sure there’s no dirt in the head’s rotating mechanism.
Before adjusting, mark the screws on the head, so you can remember their original position.
While playing in service mode on the B-side, adjust the head little by little.
First adjust one screw at a time up and down. Then adjust for both screws at the same time, up and down. During adjustment, see if the error goes away, or more ‘1’ errors appear.
Because the Azimuth Locking Pins on the head will compensate for misalignment, you might not notice slight differences immediately. Be careful to not damage your tape.
If the above does not improve the reading for head 5, it could also be a back tension issue. I have no advice on that, other then using an analog cassette back tension tester.
Good luck!
I will try to do these things and come back with details. Thank you.
