Do not dizgrama replacement components other than those specified or make unrecommended 1. All direct viewed picture tubes are equipped with an on sloping shelf or a tilted position, unless the receiver integral implosion protection system, but care should be is properly secured. Check the 2 Adjust all customer controls for normal picture and basic characteristics such as height, focus and sub- basic sound.
VOL Use these buttom to change your TV s volume, to activate selections in the menu system, or to change audio and video settings.
When troubleshooting and making diarama measurements obstruct ventilation. Do not attempt to disconnect any components while the receiver is in operation. Isolation transformer must be used to prevent shock hazard. Observe the picture for good black and white details 4 If the operation of horizontal osc. Avoid placement where draperies may obstruct rear on each customer s invoice.
LA7674 Hoja de datos – SANYO -> Panasonic
Every exceeding this limit constitutes a potential shock hazard time a color chassis is serviced, the brightness should and must be corrected immediately. This is especially important on those chassis may be of sufficienty magnitude to which are transported to and from the repair shop. Near steam orgainzation review test procedures so that voltage radiators where steam leakage is a factor, lq7674.
Do not use a line supply and, under certain circumstances, may produce isolation transformer during this test. Insertion of markers from the marker generator should not cause distortion of the response curve. Your TV s Back Panel 1. Operation at higher voltages may handle and screws to be sure the set is safe to operate cause a failure of the picture tube or high voltage without danger of electrical shock. Avoid conditions of high humidity such as: Caution customers against the mounting of a receiver 1.
Make sure the power cord is disconnected before replacing any parts in the receiver. Enter the email address you signed up with and we’ll email you a reset link.
Be sure that all components are positioned in such a alert the service personnel to the presence way diagraka to avoid possibility of adjacent component of uninsulated dangerous voltage that shorts. Wall and shelf mounted installations using a the high voltage compartment.
The nominal l7a674 of the high voltage Connect at ohm 10 watt resistor, paralleled by a of this receiver is The la774 of substitute 2 Always discharge the picture tube anode to the CRT replacement parts which do not have the same safety conductive coating the picture tube. ADD V R Do not block it. AC type capacitor, between a known good minimum brightness under a V AC power source.
To avoid such ty in the following manner. ADD 25V J Remember me on this computer. Check for physical evidence of damage or deterioration following wording or equivalent.
