My own experience with the featherweight E909 was that I had to fiddle with it several times to get it back together perfectly, but when I did, the (resulting?) lack of mechanical resistance means that the battery lasts forever, as it should with that model. I think maybe time to do some adjustment. You'll mainly need a regulated powersupply capable of sourcing exactly 1.2 volts (the minimum acceptable voltage for gumsticks).Once you have all the electrical checks done, then you can try the self-alignment routine, if that didn't make the difference. I cleared the NVRAM, performed the electrical adjustments, item 764 (V1PWM) was 2.28V instead of 2.30V. I adjusted it successfully to 2.30V, but now I have a bigger problem. I cannot pass the automatic CD adjustment anymore, it gives me 324 NG 00 0 00 error, which from my understanding is traking error. The manual recommends to perform the laser check and set the LrefPw, HrefpW and WritPw, but I don't have any laser power meter to test the power. Also, the temperature compensation value that I set is always reset to default for whatever reason I don't get even if i press pause to save the values. Bottom line: I cannot use my MD anymore, it now always enter test mode on powerup because the adjustements are not completed. Can you or anyone help me complete the adjustmnets to make it work again? A thousand thanks! Edit: How in the world should I measure the voltage drop on the R521 resistor during laser power adjustment when the resistor is just on the other side of the pdb when assembled toghether? Are they nuts for putting it on the other side? Edit2: Can anyone with a MZ-R700 tell me the values for the above settings to get mine working again?
