Hey Nani. It seems like you've tried to write everything in the title and it doesn't get clear what the problem is, because there's character limitation and it doesn't show the whole thing. I'd be glad to help you anyway I can as long as you describe the issue with a post so that I know what's going on.
You can edit your post in order to replace the missing text. Then I can submit a better answer. Just guessing, I would say the solution is to check for bad capacitors and replace or repair the mainboard as necessary.
