It's not passing the initial POST checks if it is not beeping without RAM in. Check all the power rails to ensure they are present, especially ppvcore_s0_cpu.

These are usually the worst of the bunch to solve, and is very likely to be CPU related. Good luck :)

thanks Reece i check the back, i found some part little oxidised, i clean and still the same... to much for me try fix this board now...but thank you!

Where the oxidation was, check for burnt pins on components, this is likely what was causing it (but this is now logic board repair, so take it to someone who does this if you are not comfortable doing this)

Check pp1v5 and 1v5_GPU_REG - if it is a gpu panic, than u just have to replace the cap C9560
