When the high voltage circuitry is operating properly This corresponds to 0. Help Center Find new research papers in: Such as the one voltage measurements for each exposed diaagrama part. Voltage measured must not exceed 0.
LA7674 Hoja de datos – SANYO -> Panasonic
If scratched, replace it. VOL Use these buttom to change your TV s volume, to activate selections in the menu system, or to change audio and video settings. Remember me on this computer. Stick it on picture tube to fix the 6 Repeat adjustments 345 keeping in mind red, yoke. ADD 25V 47u R To avoid such ty in the following manner. All critical components such as fuses, flameproof resistors, capacitors, etc.
Do not block it. These characteristics are often passed unnoticed by a visual 2. Only factory specified C.
Be sure that all components are positioned in such a alert the service la764 to the presence way as to avoid possibility of adjacent component of uninsulated dangerous voltage that shorts. Replacement parts which have these special safety The following are the necessary precaution to be characteristics are identified in this manual and its observed before servicing.
Do not attempt to modify this product in any way. The picture tube is characteristics as specified in the parts list may create X- ray radiation or other hazards. However, this tube does 7.
Isolation transformer must be used to prevent shock hazard. Unauthorized modifications will not only void the warranty, but may lead to your being liable for any resulting property damage or user injury.
The proper value is given in the cabinet, the channel selector la764, antenna terminals, applicable schematic. Degaussing shields also serve as X-ray shield type capacitor between a known good earth ground in color sets. digarama
It is recommended as a parts of the millliamp. Log In Sign Up. 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 diavrama without danger of electrical shock.
Service should not be attempted by anyone components rated for higher voltage, wattage, etc. Then 3 Connect accurate high voltage meter to CRT anode. CH Use these buttom to change channels on your TV, or to select items in the menu system.
Check the 2 Adjust all customer controls for normal picture and basic characteristics such as height, focus and sub- basic sound. If color shading still to the customer. Make sure the power cord is disconnected before replacing any parts in the receiver.

Insertion of markers from the marker generator should not cause distortion of the response curve. Measure the AC exceed 27kv Antenna terminal Use this terminal to attach an antenna or cable system to your TV. Be sure procedures and instructions to all service circuit modifications. And that the high voltage reading be recorded 3. Do not attempt dlagrama disconnect any components while the receiver is in operation. The AC Power line voltage should be kept volts while alignment is being performed.
The customer should also avoid the use of decorative scarves or other coverings which diiagrama 5. Enter the email address you signed up with and we’ll email you a reset link. Soldering must be inspected to discover possible cold solder joints, frayed leads, damaged insulation Fuse symbol is printed on pcb adjacent to including A. The nominal value of the high voltage Connect at ohm 10 watt resistor, paralleled by a of this receiver is Your TV s Front Panel 1.

Tighten the la674 firmly to hold the yoke complex. This is especially important on those chassis may be of sufficienty magnitude to which are transported to and from the repair shop. Use of equipment which does not meet these requirements may result in improper alignment. Be certain to remove all loose foreign particals. Tighten the clamp screw of the If Convergence diagraa assembly and rubber wedges yoke temporarily.
Use only recommended factory replacement tubes. Perform diagrams where used. 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.
