Good try Marco,

You have to have good eye sight and a steady hand to tackle this repair.

I purchased a replacement screen, still a bit of soldering and it was a success.

Hello,

I got 5 zebra stripes too. Today I opened the radio and by the way of SMD technic, using a small soldering iron and flux liquid, I refreshed as in a picture above is indicated in a square red box telling to "reflow these". I think to have done a very good job as you can see in the pictures I made.?

Unfortunately after powering on again the radio now I got 8 zebra stripes instead of 5. No lucky. The core of the problem should be there around but not exactly there I guess...

I will try something different next time.

Thank you.
