SAFETY-RELATED COMPONENT WARNING!! COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

SAFETY CHECK-OUTAfter correcting the original service problem, perform the following safety checks before releasing the set to the customer. 1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement. 5. Check the B+ voltage to see it is at the values specified. 6. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering.

(For schematic diagrams) All capacitors are in F unless otherwise noted. pF : F. 50V or less are not indicated except for electrolytics and tantalums. Chip resistors are 1/10W unless otherwise noted. k=1000, M=1000k. Caution when replacing chip parts. New parts must be attached after removal of chip. Be careful not to heat the minus side of tantalum capacitor, Because it is damaged by the heat. Some chip part will be indicated as follows. Example C541 L452 22U 10UH TA A 2520

Kinds of capacitor Temperature characteristics External dimensions (mm) Constants of resistors, capacitors, ICs and etc with XX indicate that they are not used. In such cases, the unused circuits may be indicated. Parts with 5 differ according to the model/destination. Refer to the mount table for each function. All variable and adjustable resistors have characteristic curve B, unless otherwise noted. Signal name XEDIT EDIT PB/XREC PB/REC 2 : non flammable resistor 1 : fusible resistor C : panel designation : internal component. U : B+ Line. V : B Line. Circled numbers refer to waveforms. Readings are taken with a color-bar signal input. Voltage are dc between ground and measurement points. Readings are taken with a digital multimeter (DC10M). Voltage variations may be noted due to normal production tolerances. C : adjustment for repair. Circled numbers refer to waveforms. When indicating parts by reference number, please include the board name. Note : The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified.

MECHANICAL ADJUSTMENTSFor the mechanical adjustments, please refer to the VHS MECHANICAL ADJUSTMENT MANUAL (S MECHANISM) (9-921-647-11). 2-1-3. Set-up of Adjustment In this adjustment, PAL pattern generator is connected with LINE2 input terminal. When check to tuner, connected AERIAL terminal. Check that the synchronizing signal of the Y signal has an amplitude of approximately 0.7 V and that the burst signal has an amplitude of approximately 0.3 V and its waveform is flat. And check that the level ratio of burst signal to red signal is 0.30 : 0.66. The video signal (color bar) used for electrical aligning this unit is shown in Fig. 6-2-2.White (75%)
