How to make the led brighter
To fix the dim brightness level, remove the battery and pull the plug out of the mains power. Leave it disconnected for at least 5 minutes then plug it back into mains power. You should find the brightness has retuned to normal. I have 3 of these Clock Radios and the picture attached shows the comparison between dim and normal. For some unknown reason they intermittently decide to dim themselves. This may be why Sony included a dimmer in the next model up ICF-C318. Anyway I hope this helps

Sony walkman nwz-b172f verbinden M. USB
Battery is 100% discharged. Therefore, PC's USB with 5V/500mA set up has not enough power to start up the charging process because loading current is greater than the set up, therefore USB is disabled immediately due to sudden current load.
Battery must not be discharged 100%
If it happens then the supplied AC adaptor must be used firstly because it is providing 5V/800mA power. After a couple of minutes the unit can be connected to PC without problem then it can continue the charging during file transfer, etc.

My sony radio SRF M97 AM does not work well The FM is fine
What can I do to fix the problem
I suspect there is either a problem with the radio (AM side) or most likely it is a matter of poor AM signal strength where you are and/or high levels of interference.
With FM reception the wire lead of the earphones acts as a fairly efficient antenna but AM reception is via the internal ferrite rod aerial that also is part of the tuned circuit and consequently is not only highly directional but is sensitive to vertical/horizontal orientation - if the signal is polarised vertical the antenna is more efficient when it too is vertical, unfortunately horizontal polarisation is more common.
Development of AM receivers stopped decades ago due to it falling out of favour because of high levels of interference around population centres causing much dissatisfaction and a move to FM and over the last two decades an increased interest in digital radio.

I recieve an error code c 31 00 in my system. what
There's so much information missing from this question, but assuming this is a DVD changer, it's a disc error. Either the disc is upside-down or backwards and can't be read, is too dirty/scratched or unsupported and can't be read, or the entire mechanism is jammed or malfunctioning. If there are discs in the tray and you can remove them all, remove them and see if the error goes away. If the tray will not open, either take the cover off and remove the discs, or bring it to a service center.

Hello! I have a problem
If the light blinks you need not check the fuse, its an indication that your amp has gone into protection mode due to an output failure. You will have to take it to an authorized service center because the S-master chip is a surface mounted device which needs a specialized equipment for de soldering and soldering.Even an ordinary service technician might refuse to handle this work.
