SVD800HD SERVICE GUIDE 1. Safety and regulations Introduction • The instruction given in this manual are meant for service engineers only. A good knowledge of electronics and mechanical engineering is absolutely necessary to repair and maintain the SVD800HD projector. Important notes • Should any question after reading this manual arise, please contact your local SIM2 distributor, who will be glad to help you. • In the interest of our customers we keep on improving the product.
SVD800HD SERVICE GUIDE • Do not let any kind of objects through the ventilation slits in the cabinet of the projector as they could touch the high voltage components and cause a short circuit that could, in turn, cause fire or electrical shock hazards. • If any object or liquid does get inside the projector take the power cable out of the socket immediately. • Observe instruction, regulation and notes provided in this service instruction.

SVD800HD SERVICE GUIDE 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.
SVD800HD SERVICE GUIDE 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.
