Hello, I am new on your forums, and pretty new in the AC world.
So, I have recently buyed a Samsung AC model AQV12V from a store in my country. Yesterday someone came and installed it. Last night I switched off completely the AC and removed it from the power supply.
Today when I tried to start it, the display of my interior unit was flashing continously. The device responds with some sound on some commands that I give him from the remote, but nothing actually happens and the display keeps flashing.
I have noticed Nutmeg's thread, his problem seems to be much like mine, but I can't tell for certain, because like I said I am very noob in AC devices.
So can someone tell me what I need to do? and if entering some codes are required how do I enter them and where do I find them?

Thank you.
