Here is my story on the DUO:
- redlight issue, did not boot anymore
- replaced C807 ( the famous one ) + the regulator U801
- boots again, but have severe problems on HD-channels, not locking
- after a while HD working, except the critical ones ( 8PSK here in Netherlands )
- I discovered that if the box is heated, everything works....
- removing cover, heated extra with hair-dryer and the SNR goes from 68 to 72%
- used freeze spray to identify another faulty capacitor : C848 !!
- SNR now 74% for NED1-HD ( 8PSK ) and 78% for NED2-HD. Never seen this high. Very stable
