fix: 400c instead of HD7 (working on all stations)
Thank you very much... Resistor value can change around 500-650 ohm?Mean we need test all value?
It's nice. It was my post with 10 ohm resistor on tracking and focus coils, but I'm happy to see another solution. If someone can translate this on english it will be fine. Is it 100% working solution, becaouse mine have 95 % sucess ? I can't make it work on 2-3 consoles.
begin with the lowest value (500) if there are read-problems go to 550.. and so one
sorry i have no time to test all those values ...
my value were for v9: tracking -->550-600ohm focus 620-650 ohm
v5: tracking --->550-600ohm focus ~630-650 ohm
i dont know if the resistor for tracking is needed, ist just to save the coils
but i had no problem without this resistor
this fix was just a experiment, and i have not enough time, knowhow und utils (for example oscilloscope) to make a perfekt fix
yes i meant your solution
i had some little problems with using cds...but just with an old 400c laser
my ps2s didn't read the cd/dvd slower...
but i just had 2 ps2s to test
so i think there are the same problems like with you solution, sorry
I will test it; thanks....
</Mortimer> thank you for this fix.
I have 3 boards here right now that need new lasers and they are all the Sanyo/HD7 type boards and as you all know the R-type lasers are pretty much impossible to find "new" these days.
I will try to do this mod soon myself and see how it works.
here is a link to a rough English translation.
Or maybe a 500-1000 ohm pot would be good to make fine adjustments?

and these ar the lowest working values..
if lower the ps2 wont read a cd/dvd
if higher it th signal could be to hard for the coils and they burn out
