Have brought a body - will blink LCD and will go out (not illumination).
Load new software it there was all ok, but there is no illumination.
Whether to find out from the client there was she before the software has flied cannot.
A problem I think only hardware.
On 1-st pin N300 power is on.
On 8-th pin a signal is present (~15 and vanishes) - I think this is a signal for N300 to transform power
Was a suspicion on L300, but it is not torn off (inductance I can not measure). Has all the same rewound her.
V300 in norm.
But on an output of N300 are not present necessary
Display leds in norm - submitted 5v to pin 9, 10 of LCD connector and leds is light.
From N300 to X302 road in norm.
Another N300 near at hand for check is not present.
What if not N300?
How it all generated?
