Hard problems with NovaChip V.2
Hard problems with NovaChip V.2 –
I've installed a NovaChip V.2 (Origa clone), and everything was fine (I didn't have to change the pots).
One day after that, the PS2 started to doesn't boot original CDs (like DVDX and Original Games), but PSX CDRs and original DVDs was working fine, and occasionally when DVDX booted I could run PS2 CDRs and DVDRs.
So I decided to see how many "ohms" were at the CD pots, and it was 1260 ohms. Then I decided to change it to 900ohms, and everything started to work fine.
2 days after that...
... again the same problem, sometimes original CDs boot, sometimes they don't.
So I'm concern about it cause normally I don't have to change the pots with the NovaChip, and before install the chip, all original CDs were working fine.
Does anybody knows what's happening? Or have any tip to help me?
Thanks in advanced.
You didn't mention what model PS2 you have, but it sounds like your laser is dying. Check out Lik-Sang for a replacement.
It's a V.1, but before I installed the chip. Everything was perfect. Is possible that a laser, that was good, die in just few days???
I answered this post on another forum. 900 ohms can kill the laser. You ignored my advice plastered all over the place about ohms values.
Et voila - le resultat!
The problem was the ressonator, I've replaced it and everything go back to normal.
It's strange that you mention that 900ohms can damage the laser, because the instructions that came with the NovaChipV.2 says that you should use it between 750ohms and 900ohms.
I've put this PS2 in that device that you can mensure the waves (that I don't know the name in English) and the wave was normal, ie the wave wasn't cutted. Of course in some PS2 if you change under 750ohms the wave starts to cut at the top (I don't know if I'm speaking in a understanble English )
I've tryed to find your FAQ, but I could not. Could post the link. I really wanna see your arguments.
Ok - I should have thought of that, the resonator (clock). See this thread http://www.ps2newz.net/forums/showth...=&threadid=710 and "Undrstanding DVD/DVD-R Problems" for rationale.
You are lucky with the laser. 900 ohms is a bit higher than my fry value, but as i didn't suspect the resonator ... I guarantee that 650 ohms will fry the laser. It allows twice the power through something the size of grain of soand and will send the temperature from 70 deg C to above 100 degs.
On this side of the pond, we call them Clock Crystals. They generate and supply the frequency used by the on-board components for timing (i.e. CPU, memory, I/O data transfers, etc.) and are similar in function to the quartz crystal used in electronic watches. They provide the system "heartbeat."

LOL Now, in an effort to promote a cross-cultural exhange in these global forums, see if you can properly identify the following UK idioms:
- Clapped out
- **** up
- The Tube
I love this guy. He's posted all the "idioms" I've taught him in the past year! Here are some further English synonyms (for some of them):
- Bird---------------Bint; tart
- Clapped out-----Shagged; F*cked; Shot; Gone to Ludwig
- **** up----------Balls up
- Bobby------------Old Bill; Rozzer; Copper; Filth
- Pinched----------Arrested; nicked; felt his collar
- Sacked-----------Fired; given the heave-ho
- Pram-------------African woman's breast
- The Tube--------7"; One eyed snake; The Underground
- Banger-----------Sausage (50% meat); whore; slag; old car
- Chips------------Goose (obsc.)
That last one will fool a few!
- Tosser --------- Wanker
(Added Value Section for you to do)
where can i find the resonnator?? at the Mobo or Laser Assembly? i have a V1 ntsc
