I am in a good mood today because the Ampro put a reasonable picture yesterday night. Now I can see what new picture tubes on a CRT PJ can do. Action #1 (battery voltage)
Curt, I checked the voltage of the Battery. It is kinda strange, but I am getting 0.36 volts across the terminals.
After running the PJ for 2 hrs that voltage was still 0.38 VHere is how I tested it.
The card was in the slot (I did not take it out) The PJ was turned off . (Even when the PJ was switched on, the voltage was the same). Please refer to the diagram below:-Between the points
A and B it measures 0.36 volts
B to D measures 0 volts
C to D measures 0 volts
A to D measures 0 volts (not sure about this one, forgot)
Which points are the correct ones?[added later] the points A and B are the correct ones. With reference from Curt's sitehttp://www.curtpalme.com/Ampro1500.htm
The Battery says 3.5 volts Lithium on it. Isn't it supposed to be a rechargeable battery? Doesn't look like that, since even when the PJ is powered up, the battery voltage is still the same.
Also the PJ seems to retain the memory even at this low voltage, why?[added later] actually, it does not. I confirmed this later onAction #2 (The menu issue)
I tried the blanking, Clarence was right. My top and left blanking was at the max settings.
BUT even after I set the blanking to minimum the menu won't come up. Then I saw a code for initialize test screens in the manual. THAT did the trick.
After that I also set another code, that one is right below the initialize test screens code I guess it is to reset all help screens to the default parameters.Action # 3 (convergence)
After that I proceeded to do a full convergence. This PJ's menu driven setup is very helpful.
It is a very long and tedious process but I am getting the hang of it. I did not finish it last night as it was 1 AM by the time I did the RED to GREEN convergence.
I will continue tonight.
Also, I notice that the internal test patterns are very noisy. I'll try feeding an external test pattern after I go through all the help screens.[added later] external test patterns are pristine!I'll NEVER use the internal test patterns on this again. BTW, I am usign a HTPC to feed test patterns to the PJ. The philips test pattern generator is awesome. That lets you put out dots, which the Nokia TPG does not.Thanks for all tips.
