[Console Repair/Mod Center / Re: cdrom2 lasers keep dying]

Thanks BlueBMW, hopefully I shall not need any more but, I guess I probably will . I Think it is unlikely that the one you sent me would die in exactly the same way as the others if there wasn't a reason for it.

Here's what the pots are set at at the moment. I spent ages adjusting them so the tracks wouldn't skip. Does anything look too extreme? If anyone has a KS-225A in there cd rom 2 and could take a picture of their settings that'd be excellent.

I can't see any cut traces, i think the mod totally over rode that part of the board. Here's a pic of the board:



Does it look the same as yours ?

[Console Repair/Mod Center / PCE old PAL mod reversal.]

Hello people of Pcenginefx! I got myself a pretty good condition original pc engine of e-bay witH the intention of doing an RGB mod on it and playing r-type. Once it arrived opened the casing and found it had been already modded to PAL RF.

I've checked the output over RF and it's pretty awful, white bleeds horizontally across the screen and the picture jumps and rolls quite often, so it's definitely got to go.



Looks like i'm gonna have to replace the missing resistors and capacitors to get this to work again. Could someone upload a very high rez scan/picture of the underside of a white pc engine board?

alternatively:

r137
r138
r141

and

c137 are the components that are missing. if anyone can supply info on these components it would be much appreciated!
