5. PROTECTION CIRCUITERY

EHT Protection Circuit ( PC132 board):

This protection circuit is designed against the increasing of EHT caused by electronic components faults.

The EHT Splitter in conjunction to the resistor R37 divide the EHT and the resulting voltage is buffered by IC5B, divided by R58, P4, R66 and it is applied to the positive input of the IC6A-pin7 Integrated Circuit (Test Point TP5), which works as voltage comparator.

On the negative input of IC6A-pin6 (TP12), it’s applied a voltage of 0,89 V, available from the resistive divider R55 and R56.

If the EHT value increases and the voltage on IC6A-pin7 comparator exceeds the voltage on pin6, the output of IC6Apin1 is commuted to +12 V, the voltage on IC6B-pin5 increases over the reference voltage threshold of 5,1 V applied on IC6B-pin4 from DZ1, the output of IC6B-pin2 goes to +12V and the protection circuit is activated, the protection circuit sequence of operations is described here below:

When the voltage on IC6B-pin5 exceeds the voltage on it’s negative input, the IC6B-pin2 output goes to +12 V, the protection is activated and the voltage comparator latches itself through D20. The output voltage of IC6B-pin2 is applied to the transistor T7-base by D15, and T7 goes to ON state and DL1 is switched ON. The T7-emitter voltage is applied to the T2-base and it goes to ON state therefore the EHT driver signal is switched OFF and the EHT is latched to zero. The voltage on IC6B-pin2 through the R83-R84 divider is reduced to +5V and applied to the Microprocessor, and, after about 10 seconds, it switches the projector to Stand-By mode.

Fly-back Voltage Protection Circuit ( PC132 board ):

This circuit is designed to protect the EHT circuitry against excessive fly-back voltage, it is a second protection circuit in case of faults on the precedent circuit.

The fly-back voltage of the EHT circuit is rectified by D7, filtered by C17,R17, C16 and divided by R42, R43 and P1, then it’a applied to the positive input of IC 6C-pin9, which is operating as voltage comparator. On the negative input of the same IC6C-pin8, it’s applied a reference voltage of +5,1 V by DZ1.

If the fly-back voltage increases and the voltage on pin9 exceeds the voltage on pin8, the voltage output of IC6C-pin14 goes to +12 V and the protection circuit is activated: Through R46 and D18 the voltage output on IC6C-pin14 is OR connected to IC6B-pin5 input which is operating as a voltage comparator.

Automatic Beam Current Limit Protection Circuit ( PC132 board ):

This protection circuit is designed against the CRTs excessive beam currents that may happen in case of faults on the video amplifiers or in the beam current sensing / limitation circuits of the video board PC131.

The resistors R63 and R100 are operating as current to voltage converters on the secondary circuits of the fly-back transformers, if the converted voltage, available on TP8, exceeds the threshold voltage value of 17,0 V, the protection is activated:

The voltage detected on TP8 is divided by R62 – P5 and then it’s applied to the transistor T9-base, this transistor is ON on the normal operating state.

SVD800HD SERVICE GUIDE

page - 20 -

An increasing of the beam current is converted in an increasing of the negative voltage, which drives T9 to the OFF state, and it collector goes to the level of +12 V. This voltage, through R59 and D22 is OR connected to IC6B-pin5 input, activating this voltage comparator.

The protection circuit sequence of operation is the same as reported on points 1.1 – 1.4.

7. SDG UPC2000 INSTALLATION PROCEDURE

• Check the projector EEprom release : press the INFO key on the remote control and read the “SOFTWARE REL.”

on page 2/2. If SOFTWARE REL. is 6.04 or lower, replace the EEprom using the one supplied in the kit, otherwise nothing has to be done.

• Switch off the projector and remove the power cable

• Remove the top plastic cover (see: par. 4.2.1 page 16 of the Instruction Manual).

• Remove the top aluminum cover (A) by unscrewing 8 screws (B).

• Remove the bottom aluminum cover (C) by unscrewing 6 screws (D).

• Unscrew the 2 screws (E) at the side of the convergence heat sink and lift it.

• Unscrew the screws (F) on the top of the UPC holder.

• Insert UPC in the channels (G) and press it down.

• Replace EEprom if necessary : unscrew the screws and remove the aluminum cover of microprocessor board

PC328 (the board is vertically mounted near the UPC board), extract the board, find out the integrated circuit labeled IC29, replace IC29 with the other one provided in the up-converter kit.

• Remount the microprocessor board

• Reposition all the aluminum cover and the screws.

• NOTE: When repositioning the bottom aluminum cover be careful to insert correctly the two LED 21 e 22 in the

holes (see page 6 pict. 3 of the Instruction Manual).

• Close the top plastic cover and the two screws.

• In order to use the UPC converter with the RC3100 remote see par. 3 page 8 and par. 3.14 page 11 of the

Instruction Manual, and with the RC3000 remote, see par.5 page 25 of the Instruct. Manual.
