Chapter 21 - Troubleshooting the RA-6 Chassis

Overview

The RA-6 chassis is found in the KP51HW40 and KP57HW40 models. It provides an affordable "high definition
ready" set with a 16:9 aspect ratio. It is also found in the KP43HT20, KP53/61HS20 and KP53/61HS30 as a
"High Scan" 4:3 model. Much of the circuitry is the same as in the RA-5A chassis, especially the deflection and
high voltage section. It does not incorporate a built-in DTV tuner but is able to accept two sources of HD video
from external devices using component video. It will not accept RGB or VGA sources. The power supply
contains far less components than previous models and is easier to troubleshoot. New circuit designs and
screen composition provide a sharper picture compared to previous models to take advantage of the high definition
display capabilities.
TM
The Flash Focus circuits incorporate a new feature that allows the copying of registration data from the normal
picture mode to the wide zoom, zoom and 1080i display to minimize convergence time. Details and troubleshooting
of the convergence circuits will be discussed in Chapter 28.
