Already have 2 boards with same problem. No mouse light.I have all rails and CPU too and rails for 30 seg and then board off.
What these 30 seg means? Any idea?
Boards seems pretty clean.

Pretty clean......inspect for corrosion. Common issue is corroded trace from Y1905 to U1950. Also possible is corroded reistor/traces from U6100 to SMC.

You mean Y1905 to U1900???

Well yeah, that is no rocket science.
