) and circuit diagrams (see chapter
10. Circuit Diagrams and PWB Layouts
).Where
necessary, you will find a separate drawing for clarification.
7.1
Introduction
The QM15.1L LA is a new chassis launched in LATAM in
2015. The whole range is covered by MT5593UPIJ
HSBGA-900 main IC, so-called MT5593 platform. The major
deltas versus its predecessor support
ISDB-T/NTSC/PAL-M/PAL-N, with also multi-media, CEC,
ARC, WIFI/BT,3D,SPDIF, ambilight functionality..
The QM15.1L LA chassis comes with the following stylings:
•
series xxPUG7100xx
•
series xxPUG6801xx
