Chapter 1 BG2T DESIGN CONCEPT
Overall of BG2T chassis is derived from BG2S chassis. With the introduction of the flat screen, BG2T chassis employs WEGA design concept for small screen
size. In general, BG2T have three main series; PG, HA and TG series. This Operation Manual will highlight the main difference points between BG2T and BG3S
chassis. For common items, BG3S Operation Manual (p/n: 9-965-722-01) can be used for reference purpose. Besides flat screen, BG2T also have another
exciting audio feature namely known as "Space Sound". This special feature produces significant audio effect and is only applicable for HA series. Finally overall
BG2T chassis consists of the following concept:
1-"WEGA" Design
· Flat Display
· Simple basic
· Compact
2-Reduction
· Material cost
· Part Quantity
3-Commonness
· Parts Compatibility
· Same circuit for
· each CRT
