[QUOTE="istvan, post: 1090888, member: 415398"] It seems like the biggest cap/diode are both on the 5V rail which would make sense since almost all modern circuits use 3.3V or 5V (and probably convert it down to ~1V for the main IC). Decoding HD takes a fair bit of power but it's doable with a good quality regulator. The 18V is for the LNB, that's for sure. The 12V is used for the LAN port (I can't think of anything else that uses 12V. maybe they're sending 12V to the LNB to select the vertical mode, but that's [I]almost [/I]out of specs so probably not) [/QUOTE]
