1.) Disconnect Power to Television.
2.) Remove the Back Cover.
3.) Remove the two screws holding the Main chassis to the Cabinet if necessary.
4.) Disconnect wiring harness clips to free up the chassis if necessary.
5.) Reconnect Power to the Television and turn the set ON.
6.) Locate P001 and add a jumper between pins 1 and 2 of the P001
connector as shown below.
7.) Hold jumper in place for 5 seconds. (A beep should be heard).
8.) Remove the jumper.
9.) Confirm EEPROM reset, Input source is now set to Air and not to Cable 1 or 2.
No Child Lock, and only channels 2 through 13 are in memory.
10.) Reassemble Chassis and reinstall PTV back. Set is now ready to operate.
NOTE: All customers' Auto Programming and Set-Ups are returned to factory settings.

POWER SUPPLY
INFORMATION
POWER SUPPLY ON AND OFF (STAND-BY) OPERATION EXPLANATION
PAGE 03-01
T
he power supply in the AP-93 chassis works very similar to the previous models, with
only a few exceptions. This power supply runs all the time when the AC is applied. The
use of the power supply creating the A12V supply eliminates the need for a Stand-By trans-
former. The following explanation will describe the Turning ON and OFF of the projection
television.
T
he Microprocessor generates the ON-OFF control signal as before, with the exception
that there is no Relay Driver. The schematic shows a relay driver Q003, however it is in
parentheses. This means that the component doesn’t exist in the set.
This On/Off control will perform the following :
•Turns on the regulation control signal
•Turns on the A5V and A9V regulator
•Turns on the Shut Down “Power Shorted” detection circuit
•Turns on the Horizontal Vcc supply to the Rainforest IC, I501
The Microprocessor outputs the On/Off control from Pin 35, to the PSD3 connector Pin 4.
(See Figure 1) The active state is On = High and Off = Low. The high for Power On is then
routed to Q908 and Q907. Q908 is turned On, removing the base bias for Q907. Q907 turns
off and removes D948 from the circuit of Pin 2 of I905 which is the regulation error voltage
feedback line for the regulator IC, I901.
The purpose of D948 during Stand-By, is to create a false feedback that artificially compen-
sates for the reduction in output voltage when the power supply switches to a lower frequency.
However, due to another factor, this doesn’t cause the power supply frequency to rise to maxi-
mum which will be described next.
HORIZONTAL B+ DEFEAT CIRCUIT: (See Figure 2)
W
hen the power supply goes into Stand-By mode, the Horizontal Drive signal for de-
flection is shut off. This is accomplished by Q916 and Q917. The Low out produced
from the Power On/Off pin 35 of the Microprocessor is detected by the base of Q916. This
allows the collector voltage to go high. This action turns off Q917 which removes the B+
from its collector. The Collector of Q917 is connected to the Deflection B+ pin 22 of the
Rainforest IC, I501 via pin 3 of the PSD2 connector and Pin 13 of the PSI1 connector. This
action stop I501 from producing a horizontal deflection drive signal.

POWER SUPPLY OPERATIONAL FREQUENCY DURING STAND-BY:
(See Figure 3)
W
hen the Horizontal deflection is defeated, the power supply no longer has a deflection
load. This low current demand is detected by the three resistors connected to the
source of the internal Switch MOS FET inside I901 via pin 2. Pin 4 of I901 is the over cur-
rent detection pin, however it is also the current demand sensing pin. When the current de-
mand is low due to horizontal defeat, pin 4 will be less that 1.4V and the internal frequency
will switch to 20Khz. This is caused by the Quasi Resonant circuit operation which is covered
in a Hi-Lite article.
This reduction of power supply frequency will move the frequency below the Bell of the
power supply transformer and all secondary voltages will reduce to approximately 1/2 of their
normal voltage.
Due to the fact that the power supply is still operating at 1/2 voltage output, the Green LEDs
used for visual trouble sensing will reduce in intensity, however they will remain lit. With the
exception of the TV9V and TV5V regulator. Which are turned off in Stand By.

TV9V AND TV5V REGULATOR OPERATION IN STAND-BY:
(See Figure 4)
B
oth of these ICs as well as the A12V regulator are DC to DC converters just like last
year. This is because of the wide range of input voltages from Stand-By to Normal op-
eration of the Power Supply.
The TV9V regulator (I912) and the TV5V regulator (I913) are shut off during Stand-By
mode. This is accomplished by Q906 and Q905. When the low for the power On/Off pin 35
of the Microprocessor is detected by Q906, it’s collector will go high. This action will turn
ON Q905 and its collector will go low. This will pull pin 5 of I912 and I913 low, turning off
the two DC to DC converters.
SOME SHUT-DOWN DETECTION CIRCUITS SHUT OFF DURING STAND-BY:
(See Figure 5)
D
uring Stand-By, all of the secondary voltages are reduced to approximately 50% of
their normal voltage. This could cause a potential problem with the Short Detection
circuits for shutdown. To avoid accidental shut down, Q906 also controls the activity of
Q905. During Stand-By, Q906 is turned off. This allows the Base of Q905 to be pulled up
which turns on Q905 and its collector voltage is low. Q918 is also turned off because its
base voltage is pulled low through D975. This prevents any pull-up voltage from appearing
on the emitter of Q913. The base of Q913 is connected to 6 Low Detection inputs, (See AP-
93 Power Supply Shut Down Circuit). When the power supply operates at 50%, the Short
Detection circuit could activate. By turning off Q913, no accidental shut down operation can
occur. For added protection, Q912 also prevents any Shut-Down voltage from reaching the
Gate of Q914, which is the Shut-Down SCR latch.
