Km280 runs at full speed

I have a Kenwood KM280 and it’s only running at full speed - I opened the mixer up and it looks like something has burned up on the circuit board but as I’m no electrician thought I’d ask here. Will I need to replace the whole circuit board?

Here is a closeup photo

Hi everyone,

Thanks so much for your responses - apologies for not replying before now.

I think my issue is that I’m not at all technical when it comes to electronics - we live in France and the local electronic repair guy wants 50€ just to open it - he said a minimum 3 hours work + the piece to repair / replace - sounds like I might be better getting a new mixer.

Thanks everyone for their replies and help - community spirit is great !!!!
