Samsung SH12VA1 help

[versetto]

Hello everybody!
I'm new to the forum and I need some help for my Samsung inverter air conditioner.
Some weeks ago it stopped to work.

I opened it and found the SMPS power supply of indoor unit blowed up. Instead of repair it, I removed the bridge rectifier and connected an external 12V power supply to the 12v pin near the voltage regulator.

Now the unit starts up, accepts remote control commands, but after three minutes the compressor does not start. Instead, the indoor fan stops and two leds starts to blink (the "timer" led and the "nature" led).

Do you have any idea?
Where can I find the service manual of the Samsung AQV12A1/SH12A1 inverter air conditioner?

I will be very glad if you can help me.

best wishes,
Giulio
