Sorry, on the output of rectifier I have also 26 V when measuring in DC mode. On the input of rectifier I measure 26 V. If you look at one of the photos, you can see that between the two oxide varistors, there is a transformer that stepsdown the input AC voltage. The fuse resistor its fine. On the input of transformer I measure 230 V AC.
Thanks for your reply

Power Suply Led Driver Repair Problem
Hello everyone,
I am trying to repair a faulty power suplly for a LED Light.
I measure 0 V on the output so LED dont light up, however in the input (out of rectifier), I have 60 V, so the problem must be in the middle.
Capacitors seems to be good condition, diode is also good (I tested). No burn signals elsewhere.
I attached the pcb board and a shcematic that I draw from observing the PCB. Note that there is an IC with the letters "BVYDLA" (I think its that)... its the only thing I found written on IC.
I cant find datasheets of this PCB.... -
