DC dc  and ldo out is ok?

[papele]

I do not understand.

[ильшат]

The voltage was measured at the converter and stabilizer?

[papele]

yes. when it does the defect I have no voltage on Q3 collector.

[ильшат]

And what is shown on the top of the stabilizer is working, giving out m3, 3v, and is there a m5 v? And other similar stabilizers and converters work on your board, have you checked?

[papele]

Yes, I checked all the tensions. On the main.

[ильшат]

Well then, the processor must have gone bad. Have you checked the resistance on hdmi? Was the log filmed?

[papele]
