Save the profile from the TV (folder downloadprofile.mb230) and post it here so we can see what the problem is. Did you rewrite the software?

Good day ladies and gentleman!
I am currently trying to repair a Grundig Vision 9 37 9880 T USB LCD TV for a friend that has a weird audio problem. Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.
This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).
I think the PSU buzzing comes from one of the coils near the bridge rectifier but... -
Hello everyone,
after my TV didn't turn on anymore I decided to find the problem.
I took my DMM and checked the power board - ok.

I checked the display type on... -

So i tried asking for a schematic from the company and they would not give me one. Instead they... -
