more infomation about VIDC CHIP in A5000

Post by duikkie » Wed May 22, 2019 5:30 am

someone ?

i don't have a Hsync and V/csync signaal , so no picture on a dead A5000

what does the chip needs to make Hsync and V/csync signal

first 5 volt on pin 11 vdda ? allso 5 volt vddd pin 36 or 38 ????

MUXclk on link6 = Ckv1dc pin 19 ?

vflybk on pin 22 ?

v1drq and output signal ?

all Dlines not needed for working chip i think

in other words.

which lines do i need to make a hsync and cync signaal , or Rout,Gout, Bout
it is not important what for info there is on the monitor yet

o jee we need gnd :)

is this right ?
i need clock on pin 19=ckin
i need gnd on pin 20= sink
i need 5volt on pin 43 = REFV
i need gnd on pin 18,10,42
i need 5 volt on pin 38 = vddd

then i must have a Hsync and vsync ?

no hsync yet :( REFV=3,0 volt ? REFS=2.5 volt ? =pin 12

i don't think the circuit arond pin 12 and pin 43 is not fault
i think d14 and c88 give 3,0 volt , drop from d14 ? value ??

support someone have idea ???
