Hi. have a HP All-in-One with motherboard 6050A3145401-MB-A01
The problem is no image and seems to not get full post.
The bios chip has good pulses apparently and current consumption is about 2,2 amp with some low variations while posting, then seems to stop posting and current drops to 1.7 amps and no more variations occurs.
Without graphics module is the same but less current consumption.
without ddr4 modules current consumption is always the same, no low variations.
At the end of posting sequence I can measure a few pulses in coil Ll66310, probably is VCCGT for cpu. CPU vcore is present all the time.
Tested a good bios dump and a good i3 10 gen. CPU.
Can someone point me in the right direction to repair it?
A similar schematic will be good and very helpful.
