LG 50PH470U-ZD (CHASSIS:PD32C) Service Manual ▷ View online

Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by      in the 
Schematic Diagram and Exploded View.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent 
Shock, Fire, or other Hazards. 
Do not modify the original design without permission of manufacturer.
General Guidance
An 
isolation  Transformer  should  always  be  used  during  the 
servicing of a receiver whose chassis is not isolated from the AC 
power  line.  Use  a  transformer  of  adequate  power  rating  as  this 
protects  the  technician  from  accidents  resulting  in  personal  injury 
from electrical shocks.
It  will  also  protect  the  receiver  and  it's  components  from  being 
damaged  by  accidental  shorts  of  the  circuitry  that  may  be 
inadvertently introduced during the service operation.
If  any  fuse  (or  Fusible  Resistor)  in  this  TV  receiver  is  blown, 
replace it with the specified.
When replacing a high wattage resistor (Oxide Metal Film Resistor, 
over 1 W), keep the resistor 10 mm away from PCB.
Keep wires away from high voltage or high temperature parts.
Before returning the receiver to the customer, 
always  perform  an 
AC  leakage  current  check  on  the  exposed 
metallic parts of the cabinet, such as antennas, terminals, etc., to 
be  sure  the  set  is  safe  to  operate  without  damage  of  electrical 
shock. 
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source, connect an 
electrical  jumper  across  the  two AC  plug  prongs.  Place  the AC 
switch in the on position, connect one lead of ohm-meter to the AC 
plug prongs tied together and touch other ohm-meter lead in turn to 
each  exposed  metallic  parts  such  as  antenna  terminals,  phone 
jacks, etc. 
If  the  exposed  metallic  part  has  a  return  path  to  the  chassis,  the 
measured resistance should be between 1 M
Ω and 5.2 MΩ. 
When  the  exposed  metal  has  no  return  path  to  the  chassis  the 
reading must be infinite.
An  other  abnormality  exists  that  must  be  corrected  before  the 
receiver is returned to the customer.
Leakage Current Hot Check 
(See below Figure) 
Plug the AC cord directly into the AC outlet.
Do not use a line Isolation Transformer during this check. 
Connect 1.5 K / 10 watt resistor in parallel with a 0.15 uF capacitor 
between  a  known  good  earth  ground  (Water  Pipe,  Conduit,  etc.) 
and the exposed metallic parts.
Measure  the AC  voltage  across  the  resistor  using AC  voltmeter 
with 1000 ohms/volt or more sensitivity.
Reverse plug the AC cord into the AC outlet and repeat AC voltage 
measurements  for  each  exposed  metallic  part.  Any  voltage 
measured must not exceed 0.75 volt RMS which is corresponds to 
0.5 mA.
In  case  any  measurement  is  out  of  the  limits  specified,  there  is 
possibility  of  shock  hazard  and  the  set  must  be  checked  and 
repaired before it is returned to the customer.
