Thank you very much, kind man!
I assume that there is no schematics available for this PCB, as I have couple of blown SMD components, even the high resolution picture of PCB would be helpful.

Toto je doska MR25, starsia, ktora sa uz nepouziva, nahradza sa doskou MR26. Tam je mosfet P24NF10.

Of course there is no schematics. Try to take a picture of the demaged parts please.

Pane, jestli budete chtít, tak Vám to schéma udělám .

MR26. Obvody su podobne ako MR25. Zhorete odpory su 22R 4ks. Na dalsej fotke tranzistory. Su tam pouzite bud BC 817-25 alebo BC 807-25, treba to vystopovat podla zapojenia.

Yes, the MR25 & MR26 are quite similar.
Thank you, that's the data I needed.
Thank you all, you're very kind and polite people.
