Seller Note “this item does not switch on.”
- VCore – 0.9 (OK)
- Vmem – This appears pretty low at 9, possibly short. As, Samsung K4G80325FC-HC25 isn’t normally that low.
- VDCI – 27.8 (OK)
- Display rail – 24.4 (OK)
- 5V – 5K+ (OK)
- 1.8v – 3.4K (OK)
- 12v – 6K+ (OK)
- 3.3v – 2.5K (OK)
- VCore & Vmem are missing, all others seem present (definitely 5v, 1.8v, but cannot identify some others yet showing as 0.91 and 0.96 could be display rail?)
- Perhaps the low Vmem resistance and missing voltage are linked?
- I should investigate the Vmem controller.
