hi turnip
read oldy got pin code sorted eventualy.my pace /philips box not a sky one its freeview  need  diagram as its power input has a low resistence and it shuts down external psu (12v) tried several psu but same effect,removed hdd but same problem suspect a anti reverse diode across input but its all in smd,s.
need a magnifier glass just to see them aarr as no reply from any one looks like will have to test every thing on input so may be a long job ,computer wont recognise hdd to remove recorded progs

Hi 'Cat'

Have had a few Vestel boxes where either P/S resistors went O/C or Schottky diodes went S/C - Not in your case - Also zener diodes on the main board couldn't take the heat of something or other and went S/C

Admit never tried download the HDD to computer, guess some format 'Windows' doesn't understand, though feel it might be MP4 as takes less space than most anything else - Best of luck - Chris.
