k63 Problems switching off ad not powering on

I have a problem with my keyboard.It will switch on and work for about a minute then just suddenly die and not turn back on. If i leave it for a while (few hours) then try again same thing, it would do the exact same thing.

I've came to a conclusion its a capacitor going bad, i de-soldered 2 capacitors, shorted them and then soldered them back on and the same problem but i didnt have to wait this time, hence why i think its a bad cap. I've tried everything like factory resetting the keyboard, reinstalling its firmware, tried it on dif pcs and same problem. While i wait for new capacitors to arrive, has anyone else had this problem before?

Thanks
