Sony X900E - Diagnostic Flow
« on: July 10, 2021,07:31:34 »
Good Morning all.
I'm trying to follow the diagnostic flow on the service manual for Sony X900E series, and on the flow it reference components ... just as example it says in one of the several test:
"Check POWER_MAIN C409 near CN400 on B* board"
So i found on the board CN400, it is identified, however C409 (or any other capacitors that appear on the next flows) are not identified.
for example another flow says "Check VDD C506 Voltage Is the voltage >3.0V?", same thing, there not identification for C506
and so on, many others ... The only thing identified in the board are the CN (connectors), some IC, but not R, nor C identification
I looked at both side of the board, and nothing.
 Any idea how to identify those components?
