The Panasonic RX-D12 have on display error code U01 and doesn't work in any option.
I've found transistor Q308 but I haven't service documentation therefore apply to you If you could help me to identify type of this transistor (PNP or NPN and parameters).
Thank you very much for posting the ref of transistor and to propose the service manual.My Email address is:[email protected]It replaces the one I gave earlier.I would really enjoy getting the tech. manual.

I would recommend resetting the Rosen unit. This is done by entering the "Menu" and pressing "Settings". From this screen, you select "Keypad" in the top right corner of the screen and then enter "7-5-2-3" and press "Enter". This should erase any code for Parental Control (levels 0 - 8). Also, the Rosen product states to only use "Store bought media" for CD's and DVD's meaning that it won't play all 'burned' discs. Hope this helps.- Elliot
The power supply sectionand the relay control section should be checked. There is control transistors which activates the relay control. If this transistor has damaged, of it does not get any voltage, the relay will not click. In most cases, if the output transistors got shorted, the set will come by protection state. Here you reports that only relay is not working. Just open the set and check the voltages at the "collector" pin of the relay drive transistor. You have ot disassemble the whole circuit board as these transistors are not accessable without get the boads out. Actuallly this is a very skilled work and care should be taken in all respect. If you are not aware in elctronics, and haven't proper tools and a digital multimeter, soldering iron, you can do this work. Otherwise get it repaired by any experienced service technician. OK.
You haven't said how long you cut power for when you flipped the breaker. These things sometimes have heavy capacitors in them taht will take a time to discharge and allow everything to reset. Before you call a service tech, unplug the unit (or flip the breaker, whatever) and leave the unit disconnected for half an hour. This may just be all you need to do.
Here is the link to the user manual if you need it;
although of course it doesn't list that error code and panasonic no longer support the model on their site except for the user manual. If you don't mind paying $19.50, then these guys have the service manual available which almost certainly will list the error codes and their solutions;
Sorry I had no luck finding that one for free.
My guess is that the lens needs cleaning, and that the error code simply means "bad disc" or something similar.
Best way to clean the lens is with a cotton bud/ Q-Tip moistened (not wet) with gin - nothing else works as well or as safely. This should be easy to do as you have direct access to the lens, just be gentle.
If you get no luck from that then the best i can suggest is to contact panasonic direct;
and see if they can tell you what the code means, if they do, and you need help solving the problem, please ask again.
Good luck, I hope this helps
