I got this Sony DHR-1000 miniDV recorder that didn't power on. Opening it up I saw that R115 was split in two so I replaced that, and measured that Q101, Q102 and Q103 were bad so I replaced those too. Plugging it in gave the correct voltages, until I tried turning the machine on. No more output voltages. I replaced PH101 but that didn't help. I replaced all the capacitors and now when plugging it in, I get the correct voltages for about a second then it disappears. No chance of turning the machine on. What am I missing here? I've tried swapping the power supply with a good one just to make sure the rest of the machine works, and it does, so it's something on this board that's making my head hurt.
