WARNINGS AND CAUTIONS
CAUTION
Short c rcu t the anode of the p cture tube and the anode cap to the metal chass s, CRT sh eld, or carbon pa nted on the CRT,
after remov ng the anode.
WARNING!!
An solat on transformer should be used dur ng any serv ce to avo d poss ble shock hazard, because of l ve chass s. The chass s of
th s rece ver s d rectly connected to the AC power l ne.
! SAFETY-RELATED COMPONENT WARNING!!
Components dent fi ed by shad ng and ! mark on the schemat c d agrams, exploded v ews, and n the parts l st are cr t cal for
safe operat on. Replace these components w th Sony parts whose part numbers appear as shown n th s manual or n supplements
publ shed by Sony. C rcu t adjustments that are cr t cal for safe operat on are dent fi ed n th s manual. Follow these procedures
whenever cr t cal components are replaced or mproper operat on s suspected.
ATTENTION!!

SAFETY CHECK-OUT
After correct ng the or g nal serv ce problem, perform the follow ng
safety checks before releas ng the set to the customer:
1. Check the area of your repa r for unsoldered or poorly soldered
connect ons. Check the ent re board surface for solder splashes and
br dges.
2. Check the nterboard w r ng to ensure that no w res are “p nched” or
touch ng h gh-wattage res stors.
3. Check that all control knobs, sh elds, covers, ground straps, and
mount ng hardware have been replaced. Be absolutely certa n that
you have replaced all the nsulators.
4. Look for unauthor zed replacement parts, part cularly trans stors,
that were nstalled dur ng a prev ous repa r. Po nt them out to the
customer and recommend the r replacement.
5. Look for parts wh ch, though funct on ng, show obv ous s gns of
deter orat on. Po nt them out to the customer and recommend the r
replacement.
6. Check the l ne cords for cracks and abras on. Recommend the
replacement of any such l ne cord to the customer.
7. Check the B+ and HV to see f they are spec fi ed values. Make sure
your nstruments are accurate; be susp c ous of your HV meter f sets
always have low HV.
8. Check the antenna term nals, metal tr m, “metall zed” knobs, screws,
and all other exposed metal parts for AC leakage. Check leakage
as descr bed below.
Leakage Test
The AC leakage from any exposed metal part to earth ground and from
all exposed metal parts to any exposed metal part hav ng a return to
chass s, must not exceed 0.5 mA (500 m croamperes). Leakage current
can be measured by any one of three methods.
1. A commerc al leakage tester, such as the S mpson 229 or
RCA WT-540A. Follow the manufacturers’ nstruct ons to use these
nstruct ons.
2. A battery-operated AC m ll ampmeter. The Data Prec s on 245 d g tal
mult meter s su table for th s job.
3. Measur ng the voltage drop across a res stor by means of a VOM
or battery-operated AC voltmeter. The “l m t” nd cat on s 0.75 V,
so analog meters must have an accurate low voltage scale. The
S mpson’s 250 and Sanwa SH-63TRD are examples of pass ve VOMs
that are su table. Nearly all battery-operated d g tal mult meters that
have a 2 VAC range are su table (see F gure A).
How to Find a Good Earth Ground
A cold-water p pe s a guaranteed earth ground; the cover-plate reta n ng
screw on most AC outlet boxes s also at earth ground. If the reta n ng
screw s to be used as your earth ground, ver fy that t s at ground
by measur ng the res stance between t and a cold-water p pe w th an
ohmmeter. The read ng should be zero ohms.
If a cold-water p pe s not access ble, connect a 60- to 100-watt trouble-
l ght (not a neon lamp) between the hot s de of the receptacle and the
reta n ng screw. Try both slots, f necessary, to locate the hot s de on the
l ne; the lamp should l ght at normal br ll ance f the screw s at ground
potent al (see F gure B).

ANODE CAP REMOVAL PROCEDURE
WARNING: H gh voltage rema ns n the CRT even after the power s d sconnected. To avo d electr c shock, d scharge CRT before attempt ng to
attempt ng to remove the anode cap. Short between anode and coated earth ground strap of CRT.
NOTE: After remov ng the anode cap, short c rcu t the anode of the p cture tube and the anode cap to e ther the metal chass s, CRT sh eld, or
carbon pa nted on the CRT.
HOW TO HANDLE AN ANODE CAP
1. Do not use sharp objects wh ch may cause damage to the surface of the anode
cap.
2. To avo d damag ng the anode cap, do not squeeze the rubber cover ng too hard.
A mater al fi tt ng called a shatter-hook term nal s bu lt nto the rubber.
3. Do not force turn the foot of the rubber cover. Th s may cause the shatter-hook

Note: The follow ng adjustments should always be performed when
replac ng the follow ng components, wh ch are marked w th
Y on the
schemat c d agram on the A Board:
A BOARD: IC601, PH601
1. Us ng a Var ac, apply AC nput voltage: 130 + 2.0/- 0.0 VAC
2. Input a dot s gnal.
3. Set the PICTURE and the BRIGHTNESS controls to m n mum.
4. Confi rm the voltage of A Board TP-600 s <136.6 VDC.
5. If step 4 s not sat sfi ed, replace the components l sted above, then
repeat Steps 1 – 3.

PREPARATION BEFORE CONFIRMATION
1. Us ng a Var ac, apply AC nput voltage: 120 ±2 VAC.
2. Turn the POWER sw tch ON.
3. Input a wh te s gnal and set the PICTURE and BRIGHTNESS controls
to max mum.
4. Confi rm that the voltage between C546 (+) or TP503 and ground s
more than 97 VDC.
HOLD-DOWN OPERATION CONFIRMATION
1. Connect the current meter between P n 11 of the FBT (T505) and
the PWB land where P n 11 would normally attach (See F gure 1 on
the next page).
2. Input a dot s gnal and set PICTURE and BRIGHTNESS to m n mum:
IABL = 100 ± 100µA.
3. Confi rm the voltage of A Board TP-600 s 135.6 ± 1 VDC.
4. Connect the d g tal voltmeter and the DC power supply v a D ode
1SS119 to C546 (+) and ground (See F gure 1 on next page).
5. Increase the DC power voltage gradually unt l the p cture blanks out.
6. Turn DC power source off mmed ately.
7. Read the d g tal voltmeter nd cat on (standard 117.0 VDC).
8. Input a wh te s gnal and set PICTURE and BRIGHTNESS to
max mum: IABL = 1350 ± 100µA.
9. Repeat steps 4 to 7.
