Cant switch off -Bootloop

Hello ,
2days ago , i had an accident with my P780 , it touched some water where Power button is , my 1st reaction was to clean it carefully.
After that , i left it for 1 hour about.Then, when i take it , it was already on bootloop...(switch off , says lenovo (logo) and then switch on again) ,until no battery left.
when i charge it , red light is on so i think battery works fine. the same when i connect it on my pc
Next day, i tried to flash it , and i did it 3 times with different roms.After every time flash finished, my phone was dead. so i had to hard reset it (red button near battery), then the same thing again ....Bootloop , switch off and switch on..
I tried to find out why i cant switch it off ,( it first place i thought my power button has a damage) ( i am not sure yet)
when i Power button +VolDown , it tells me about meta-mode
When i Power button + VolUP , does nothing at all ( again reboots)
when i power button + volUp + volDown (trying to enter on recovery mode of each custom Rom) i am managed to enter for about 1-2 sec and then reboots again.
If i just long press power button does nothing at all.
I tried to flashing it 3 times (Green cycle) so i think i did well .
I dont know which is the problem...
maybe Hardware dmg ?
thanks in advance

What ROM did you have first?
Did you try to dry first your phone ?

i place this inside rice for about ~12 hours ,also i heat it with hair dryer about 5 min , then screen was very very hot.
I dont know ....When i touch it and i shake it near my ear , i think i can hear something is moving inside phone , but never drops me from my hand (i think 1 time happends about 4 months ago)

I had X-vibe Rom by Xakep for about 3-4 monts when this happened.

Ok i will try it , i just put it out from rice, and i charge it , but this time, doesnt open alone....so this is good thing or not ?
I am afraid if i try to touch my Power button my phone will be complete dead ,if i try to press the red button , then bootloop again until out of battery.
