Important Service Notes
Maintenance and repair of this receiver should be done by qualified service personnel only. Warning The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power receptacle, when servicing the chassis. To prevent electric shock, do not remove cover. No user serviceable parts inside. Refer servicing to qualified service personnel. Servicing of High Voltage and Picture Tube. When servicing the high voltage system, remove static charge from it by connecting a 10 k W Resistor in series with an insulated wire (such as a test probe) between picture tube ground tag and high voltage lead (AC line cord should be disconnected from AC outlet) 1: Picture tube in this receiver employs integral implosion protection. 2: Replace with tube of the same type number for continued safety. 3: Do not lift picture tube by the neck. 4: Handle the picture tube only when wearing shatterproof goggles and after discharging the high voltage completely. X-Ray This receiver is designed so that any X-Ray radiation is kept to an absolute minimum. Since certain malfunctions or servicing may produce potentially hazardous radiation with prolonged exposure at close range the following precautions should be observed: 1:When repairing the circuit, be sure not to increase the high voltage to more than 30.0
kv, (at beam 1000µA) for the set. 2:To keep the set in a normal operation, be sure to make it function on 25.7 kv ± 1.5 kv (at beam 1300 µA) in the case of the set. The set has been factory - Adjusted to the above mentioned high voltage. If there is a possibility that the high voltage fluctuates as a result of the repairs, never forget to check for such high voltage after the work. 3: Do not substitute a picture tube with unauthorised types and/or brands which may cause excess X-ray radiation. Before Returning the Receiver Before returning the receiver to the user, perform the following safety checks. 1:Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the receiver. 2:Inspect all protective devices such as nonmetallic control knobs, insulating fish papers, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacity networks, mechanical insulators etc. Service Mode In addition to the method shown under model DV 5935H, service mode may be implemented by the following method. 1: Insure that receiver is switched off. 2: On the front of the receiver, simultaneously press and hold w (volume down) and CH v (channel up) whilst switching on the power switch. 3: After switching on keep the two buttons depressed for three seconds before releasing. Continue as shown under DV 5935H
