helped needed for a 70002

Hi

I tried to install a MI chip into my v12 with a Neo-fix vii; and had no joy.

I removed the chip and the neo-fix; still didnt work. Now the situation is:
+A/V output ok
+Laser moves, and shines
-but CD doesn't spin

I have tried to fix in a brandnew laser, still the same

Does this sound familiar to you? Any help is appreciated.

What is the exact problem ??
Black screen ??
No on ??
No cd spin ??
Red screen of death ???
Go to brownser ????

Thanks for replying.
The problem is
------ No cd spin -------

your system is dead send it to me and il send you $1 .. Jk remove mi and test if no spin then chek all fuses ps13 culd be your problem replace with .4a and make sure ther is no splatter on the board shorting things out.

You have blow the resistors in tracking / focus place .
Replace with the same value


red circle tracking
black focus

sitll no spin after removing the MI
all fuses seem to be ok.

it's driving me

I blew one of tracking resistors before. At that time, there was no connectivities between two ends of the resistor. But now I am not seeing that sympton...

my tracking resistors has got 683 on them; when i measure i got 1646 for the one on top
and 1836 for the one below

the 303 focus resistor is 1888 ohm
the 163 focus resistor is 866 ohm

do these values look OK to you?

[villasg]

I remeber that :
303 is 30.000 ΩHM
683 is 68.000 ΩHM
Anyway you can replace the tracking ( booth ) with 130.000 ΩΗΜ resistor
and the focus ( booth ) with 43.000 ΩΗΜ resistors .
Thanks to the summone for that.
