Question about Pioneer Televison & Video
Can i internaly adjust the focus without disturbing the c.r.t.s . and what is the procedure. also how do you remove the front speaker grill thanks jeff
Yes, you can adjust the focus of the CRTs without causing other issues if you exercise some care in the process. There are two types of focus adjustments in your TV, electrical and optical. The electrical focus is more likely to change over time than the optical focus. That's because the optical focus is mechanical and would likely only need adjusting in the event of a CRT replacement. The electrical focus controls are located behind the front speaker grill and the front access panel. Pioneer TVs will either have pop-on/off connectors where all you need do is grab and pull, or it may have a few philips screws securing the grill. The screws are generally hidden behind the plastic molding strips just above the grill assy. (they are snap on/ pull off) There will be a small, black control assembly located behind the access panel. There will be 3 focus controls and 3 screen controls. The screen controls adjust the intensity of each CRTs brightness.
