Hi to all.

I have some strange problem with one unit RNS 510 from year 2009, HW H40, SW 1100.
After power on and play music work well 20 minute after this time missing the sound on spekers, stop to play and the unit stay on, if I lisen radio or cd, no sound after this 20 minute !

The same problem is also in the car or on desk !

The audio amplifier module is ok, because had 5,8 V on output speakers from gnd !

Can tell me some one if is some software problem ?
I try to find what version of soft had this unit and I can't see it.
When I go in setup I see FM, AM and DAB and I need to have FM, AM and "Version info" but is missing.

Some help to fix this problem on this unit ?
How I can see what version is instal in this unit and what version can be instal for fix this sound problem ?

Thanks.

the output-amplifier is known to fail in these units, should been an own board in the unit
maybe a problem by head, try to cooling it, search for bad soldering, capacitors, Amplifier-IC
if you detect the board as defective and not able to be repaired, it can be changed
