Hi Tom,

I will try to use these diodes
BY500-1000

What do you think of that?

I bought 40 of this diodes and selected them so it differed max 1mV.
After replacing these and Q935, the TV started :-)
It worked for about an hour before it blow up again and now I will give up and never ever try to repair any PSU of this type!!

Ah Vestel, aren't they great?!
Did you also replace the little SMDs and driver chip for Q935?
