Does anyone knows the values of the resistor at place C99, C100, C101, C.102, C103, C104,C105,C106 and C107.
They all seems tpo be the same, with next text on it : 104Z 25V.
Seems that almost all above mentioned resistors are damaged.

What colors are the resistors?
If I correct recall, someone could identify them for the colours ... I still need to make the Electronic, Radio and Television course [I could pick the course today, but I delayed this a little]. Also, I need to re-read the one about Digital Electronics ... Maybe someday, I will be good at this ...

well to be honest i was wrong it is not a resistor but a condensator (orange/yellow ones).

104Z == 0.1 uf == 100nf == 100.000pf of capacity
and 25volts is the max voltage rate.
PD: for a quick test of those elements...
with a ohmeter,
SHORT-CircuiT = BAD
OPEN CIRCUIT= GOOD

thx, well they are visually damaged, outside is totally off!!!.
When power on the MSX you see monitor reacting, but it keeping black.
Bower led is on, and rensha led works.
for rest it is dead, no diskdrive no pause.
So i hope that when i change them for new the roms on pcb still working.
there is on board visually no more damage.
