How to fix LCD

I realize there may be a certain amount of information lost in a possible translation, but you haven't given us much to go on, Reydel.

First of all, if I take your question literally, then the answer is no, iFixit cannot fix your phone. They do not do repairs; they are a resource for people who want to know how to repair their own devices. As such, we can help you figure out how to fix your own phone, but neither the company itself or the volunteers who help out on the site can do it for you.

Next, it's not clear exactly what's wrong with your LCD. Again taking you literally, it's generally not possible to actually repair a damaged or nonworking display; the only real fix is to replace it.

I wasn't able to locate any iFixit-style written instructions for fixing your phone, but I did find a YouTube video that steps you through the process if you want to do it yourself.
