Welcome in the hell

I bought this camera on ebay because of symptoms (is possible to turn on after enough tries)
It's look like power source problem (obviously capacitor).
But

It's no so easy as seems to be

There is no service manual, nothing.
I started from beginning .. power supply


Everything is rear-lacquered:( When I can measure something I need to scrape the contacts

Next straight forward step check all capacitors ... hmm tantal



All seems to be OK and next step was connect additional boards to check if power consumption will increase.
But nothing.
When I put together all boards camera looks good started but on display si only one vertical line and after that nothing.

Some photos:



There is lot of potential problems like RAM, CF card, display, CPU or FPGA.
Suggestion's are welcome.
To be continue ...
