The television may fail to display an animation image correctly when a signal having a vertical frequency of
72Hz or higher is input to it.
The television differentiates the signal modes according to the horizontal and vertical frequencies and the
horizontal and vertical sync signal polarities. Note that different signals having all these elements alike may
be handled as the same signal.
Displaying images with more than 768 lines of vertical resolution a Full display (compressed display) can

4. Service points
The PWB assembly which has used lead free
Lead-free solder
This product uses lead-free solder (unleaded) to help protect the environment. Please read these instructions
before attempting any soldering work.
Caution: Always wear safety glasses to prevent fumes or molten solder from getting into
the eyes. Lead-free solder can splatter at high temperatures (600℃).
Lead-free solder indicator
Printed circuit boards using lead-free solder are engraved with an "F."
Properties of lead-free solder
The melting point of lead-free solder is 40-50℃ higher than leaded solder.
Servicing solder
Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended. Although servicing with
leaded solder is possible, there are a few precautions that have to be taken. (Not taking these precautions may
cause the solder to not harden properly, and lead to consequent malfunctions.)
Precautions when using leaded solder
Remove all lead-free solder from soldered joints when replacing components.
If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the
lead-free solder has been completely melted (do not apply the soldering iron without solder).
Servicing soldering iron
A soldering iron with a temperature setting capability (temperature control function) is recommended.
The melting point of lead-free solder is higher than leaded solder. Use a soldering iron that maintains a high
stable temperature (large heat capacity), and that allows temperature adjustment according to the part being
serviced, to avoid poor servicing performance.
Recommended soldering iron:
Soldering iron with temperature control function (temperature range: 320-450℃)
Recommended temperature range per part:
Part Soldering iron temperature
Mounting (chips) on mounted PCB 320ºC±30ºC
Mounting (chips) on empty PCB 380ºC±30ºC
