Hi, i have this TV Blaupunkt 32'' LED on service

Surge strike and burned many components.
Replaced D3 and D5 diode , replaced R65 R66 R67 R68 resistors ( couldnt see what markings were on them - i replaced with 1R5 and 3x 1R0 resistors )
Replaced mdf7n60b mosfet with K3673 mosfet , replaced R52 and R58 resistors - also burned.

U2 is not shorted anywhere but i suspect it is also burned since massive surge came over R52 resistor.

On U2 i 4.5V AC current on ALL THE PINS , need help.

Cant read model on U2 chip, also, not sure if the R65, R66, R67, R68 are correct value.

Thanks comrades!
