I am working to complete the restoration of my Nintendo Helifire. I am working on the monitor which is why we are here today.....
It is a Sanyo 20-DZC monitor in a box which is the predicessor to the 20 EZ. All I have for the schematics are a very blurry version found in the Radarscope schematic set. For those of you that will tell me it is the same as the 14" version it is similar but not the same. I can tell that from the schematics for both which I compared. I have also been comparing it to the later EZ version to help answer a bunch of questions. So, after all that, I will outline the remaining question as this thread moves along.
Question 1. The C606 Cap in the monitor currently is a 680uF - 160V. Main B+ Filter Cap I think. All the scheamtics, 20-DZC, 14-APL, 20-EZ... show it as a 470uF - 160V. I checked the CAP in both my DK and Radarscope which are 20-EZ's and they are 470. Which do you think is correct?
Some pictures of the chassis can be seen in my restoration thread here. Picture #2 has the CAP on the far left of the picture. It is very hard to tell if that CAP has ever been replaced. You can see a preview of some of the other questions in the restoration thread.
