207 sw trip computer screen hk

Hello. Shortly after having the interior and exterior detailed cleaning done, I noticed that the display on the trip computer screen had gone. When the light hit it, there was a very faint image, but it was gone, meaning there was no display. They said they had cleaned the interior of the vehicle with steam. I don't understand why this happened. I wanted to consult with experienced friends. Thank you.

I had the screen of my car removed. I was going to search for it in electronics stores and auto parts stores, but when I saw those LEDs, my world went dark. Now my question is; could this problem be caused by the fuse? http://imgur.com/a/JIYvb3r Unfortunately, I couldn't find the image upload option. I would appreciate it if you could look at the link.

Luckily I tore it down. The trip computer card was oxidized due to steam cleaning. After cleaning with thinner, strengthening some solder, etc. it became functional.
