Re: 94V-0 E307069 GE-1 (HM65) there is vcore but no
Maybe I explained the problem a little confused.
There are all voltages with no CPU installed. When I insert the CPU, the card draws 1.2A,
then the vcore regulator turns itself off. I took all the capacitors from a working card and put them on.
The CPU runs on another card, so the CPU is intact.
There is a problem that shuts down the regulator when consumption goes over 1.2 amps.
There are two of this card. One works well, and I measure it to fix the faulty one, and the other. The problem is as follows; The card turns off when the current reaches 1.2 A, installing and starting the processor on the card. I get all the voltages without a processor installed. VCore 1.05, GCore 1.1 and other voltages of 5 V, 1.8 V and 3.3 V are available. There is no faulty mosfet, no heated voltage regulator. I removed all the tantalum and aluminum capacitors from the work card and attached it to the faulty card. Nothing has changed. When I insert the CPU, the PGOOD ISL95870 output drops...
I'm experienced in electronics, but I'm just training myself in monitor repair, and this is the first time I've come across such a failure. This breakdown application is an AOC 917Sw + from our school another school
The fault is generally intertwined or shaded colors and 5-6 white lines at the bottom edge.
I've recorded a short video to illustrate this and I share the link below:

Perhaps repairing is beyond my means (but for now maybe it has a very simple solution.
