VP1770/J71C DEAD

Hi there.

Information printed on the board: 177HM407 88.01.25 2202109104 VER:5.07

Information on the back: VP11770 OA J71C

The monitor doesn't work.

Didn't find any reasonable problem.

The Power at the 3842B go up to 17V at the start and then goes down to about 2V.

Removed the HOT (it was ok) and turned it on to test and the power at the 3842B is good but Resistor R457 burned right away (can not recognise it).

Any thoughts?

Best Regards...
