|
|
Hey All,
I recently picked up a non-working MK cheap and once i got it open in saw the CPU is FRIED!
I'm confident i can solder the new components on to the board. The main issue is that none of the other components discussed in this thread show any physical signs of damage.
I went over them all with a digi multimeter and these are my findings:
- 3.3v switching regulator = 9-9.80v across various pins
- Mosfet = 8.90-9.80v
- FUSE 2.00A 1206 = 9.80v before and .80v after
- CAP TANTALUM 100UF 10V = 9.80v
- C6, C42, C46, C54, C69, C196 = 9.80V
- C107, C104, C102 = 9.80V
Could anyone tell me if these are similar to what they found with there MK?
Should i test any other components?
I've gone and ordered the following from digikey:
IC H8S/2300 ROMLESS 128QFP / D12320VF25V-ND
FUSE 2.00A 1206 VFAST SMD / MFU12062.00CT-ND
CAP TANTALUM 100UF 10V 10% SMD / 495-2220-1-ND
I cant find a replacement 3.3 switching regulator or mosfet in Australia, Digikey wont ship me one,anyknow where to get one?
any help would be great.
Peace, A |
