Good afternoon!
There was such a problem, this I / O block burned out, the elements R60, R61, R62, R68, R71, R72, VR2, D20 were badly damaged, and now it is impossible to read their markings. Power board (lowest) PSW1.1.
Maybe someone has such a block, and if it is, could you take a photo of the power board (the lowest one), all the ratings are visible there, except for VR2, it is on the other side of the board, near the PWM controller.
Thank you!
