RH32 allows ABL fluctuations tomanipulate the Trigg er Point of Shut
Down as screen brightness varies. ABLis inverse proportionate to brightness.
This prevents false triggering.
Any fluctuations in High Voltage willalso be reflected by the 50P output P/P.By monitoring the 50P (50 Pulse) risesin High Voltage will be sensed. If HighVoltage climbs too high, DH15 will fire
and trigger a sh ut down event.
If the Vertical Output IC has a problem,R629 will sense the current rise. The
voltage drop will be reflected at the baseof Q604 turning it on and producing a
Shut Down high.

DP-5X ABL CIRCUIT EXPLANATION
PAGE 02-04
(See ABL Circuit Diagram on the next page for details) The ABL voltage is generated from the Flyback transformer TH01 ABL pin (8). The ABL pull-up resistors are RH27 and RH28. They receive their pull up voltage from the SW +115V which is the B+ line for Deflection cre-ated in the Power Supply. ABL VOLTAGE OPERATION The ABL voltage is determined by the current draw through the Flyback transformer. As the picture brightness becomes brighter or increases, the demand for replacement of the High Voltage being consumed is greater. In this case, the Flyback will work harder and the current through the Flyback increases. This in turn will decrease the ABL voltage. The ABL voltage is inversely proportionate to screen brightness. Also connected to the ABL voltage line is DH16. This zener diode acts as a clamp for the ABL voltage. If the ABL voltage tries to increase above 10.5V due to a dark scene which decreases the current demand on the fly-back, the ABL voltage will rise to the point that DH16 dumps the excess voltage into the 10.5V line. ACCL TRANSISTOR OPERATION The ABL voltage is routed through the PDT2 connector pin 3 to the Signal PWB. Then the ABL voltage is routed through the acceleration circuit RX45 and DX01 to the base of QX12. Under normal conditions, this tran-sistor is nearly saturated. QX12 determines the voltage being supplied to the cathode of DX00, which is con-nected to pin 78 of the Rainforest IC, IX01. During an ABL voltage decrease due to an excessive bright circum-stance, the base of QX12 will go down, this will drop the emitter voltage which in turn drops the cathode voltage of DX00. This in turn will pull voltage away from pin 78 of the Rainforest IC, IX01. Internally, this reduces the brightness, contrast and color gain voltage which is being controlled by the I2C bus data communication from the Microprocessor arriving at pins 28 and 30 of the Rainforest IC and reduces the overall brightness, preventing blooming as well as reducing the Color saturation level to prevent color smear. ABL SWITCH QH03 AND QH05 This chassis has the ability to change the Side Panels when watching a NTSC 4X3 image. When a 4X3 images is displayed on a 16X9 set, the sides do not reach the edges. To avoid excessive ageing at the 4X3 display area, the side panels IRE levels are raised. However, sometimes the customer may want to turn the side gray panels off. Through the Video Advanced features Menu the customer can do this. When the Side panels are turned off, the overall average ABL level for the image is reduced. To compensate, QH03 ABL Switch is turned on. The Micro-processor in the Digital Module tells the Sub Microprocessor IC I001 via I2C communication to output a high from the DAC lines pin 88 or 89. This high is routed through the PPT2 connector, either pin 1 or 2, to the base of QH03 or QH05 turning either one On. This adds either Resistor RH42 or RH43 to the ABL pull up circuit and the ABL level drops slightly to compensate for the loss of brightness when the side panels go black.
RH32 manipulates the trigger point of shutdown dependant upon the ABL level avoiding false triggering. NOTE: For the Circuit connected to the Xray Protect line, see the PROTECT-OVP (A to B) SHUTDOWN DIA-GRAM for details on Page 01-04.

SIGNAL POWER SUPPLY P.W.B. Preparation for adjustment :
• Set the AC input power supply to 120V ±1V. • Receive a Crosshatch pattern signal. • Set the Contrast, Brightness controls to maximum. • Heat Run for at least 30 seconds after the power is turned on. • Audio : Mute.
Adjustment procedure • Check the voltage of the Power supply as shown in the table below. • When the power switch SM01 is turned ON, check that the relay is also turned ON. • If using a dummy load, it is necessary to short S901 primary side terminal by jig.
Remarks The power supply voltage should be normal. There should be no abnormal operation of the protection circuit. (Latch) There should be no parts that generate an abnormal amount of heat. Make sure that there’s no burning smell or smoke. Table 1-1. DP55 and DP-57 Chassis
Protection Circuit check
POWER SUPPLY PROTECTION
Apply a 1K ohm short to ground from PPT3 pin 7 (Sig +5.6V line).
S901 should turn off but this is not a Latch state
(Power back on by remote control 2nd push).
• 1st push power off.
• 2nd push, power on.
