My melody water machine alkine water didn't comeout. but the acide water does come out

Most likely the acid ate the internal power supply, but if you can dis-assemble it and clean any trace of gunk with a toothbrush and electronic cleaner, including the fuse and it's contacts, maybe you'll get lucky.

melody strings = C (high) C (low)
drone = G D G or G C G
resonant strings : according to raga (based on C)
all can be tuned a hundred ways but this is standard

Read your user manual about keyboard split. OFTEN the rhythms use the keys below F sharp for the chording of rhythm. When in this mode, you should restrict your melody to notes above F sharp that is to the left of middle C. If you play melody below this it will confuse the rhythm chording. You can likely change the split point of the keyboard, however, the F sharp split is the standard and I would suggest staying with it.

Watch YouTube videos on "cleaning harmonica".

Hopefully you didn't take it on a flight as sometimes they use bomb detecting equipment that subjects cargo to either high levels of radiation or high electro-magnetic fields. This can damage the equipment. It sounds like the processor is not running. There usually is a screen contrast control that can be turned enough that the screen appears blank, but usually you can get a sound out of the unit without reading the screen, Look in your user manual for a FACTORY reset or restore and pperform that procedure. If that doesn't work, then repair is in order. If unit has been vibraated during transportation, it is possible a cable has come off inside. Since you just bought this, EXERCISE you warranty immediately.

The headline has two different mics listed... a Shure 87a and a Beta 98/S... not sure which you really have... Normally leaving the mic in the car should NOT have affeected it, although you haven't told us the environment such as humid or immersed in water, etc. On the chance it may have had condensation I would put it over a hot-air register for a few days to insure there is no residual condensation .. DO NOT place in an oven to try to speed this up. If there is condensation on the diaphram it needs to evaporate and vent slowly. Also you can look for corrosion on the plug contacts.

The blow reed plate is backwards... either upside down or facing the wrong way. The open end of the reeds needs to be opposite to the draw reeds.

Test it with batteries to see that it works, if it does, then you probably have the WRONG adapter.

Not sure if your "booklet" is the full user manual... if not go to this site and go through their "hoops" and download the full user manual. It shows how to put the unit in the mode that merely lights the keys and plays the rhythm, unlike the "demo" mode.

Note the manual is free via the Retrevo site... just have some of those annoying hoopps like email address and entering numbers.
