hi guys, we replaced 216-0674026 with 216-0674022 on Acer 5536 and checked the BIOS dump (OPROM00.ROM) for RS780 and it is correct but still no image. Can this 216-0674022 substitute 216-0674026 with modded BIOS?
before there were artefacts now there is no image but 216-0674026 with 216-0674022 are compatible when they serve only as Northbridge. When the Integrated graphics are used there might be a problem or need modded BIOS. We use Finetech FINEPLACER PICO RS to replace or reball BGAs (we have done hundreds D) and so we are sure that the BGA is placed correctly.
