How to fix problem of the dvb atlas200 HD with picture fricking
and output power instable due of the anomaly with the DSP M88D3103
Or Démodulator clock which is provided by the tuner.it's generate by Cristal of 27 MHZ
It displays unclear picture of the menu, hardly visible and loss of channels because the output stage is driven by M88 D3103
After checking the two necessary voltages 3.3 V and 1.8V To power the circuit
we made check at the C45 (condensator) from which is the clock is provided to the pin clock of circuit
the value tested is more higher than expected
after changing the cristal in the tuner the problem is fixed
