SECTION 1 GENERAL
The circuit boards used in these models have been processed using Lead Free Solder. The boards are identified by the LF logo located close to the board designation e.g. H1 etc [ see example ]. The servicing of these boards requires special precautions to be taken as outlined below.
Lead Free Soldered Boards
example
Lead Free Solder material must be used to comply with environmental requirements of new solder joints. Lead Free Solder is available under the following part numbers :
Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.
For more information on the use of Lead Free Solder, please refer to

CAUTION
SECTION 1 GENERAL
How to replace the fuse. Open the fuse compartment with a screwdriver blade and replace the fuse.
FUSE
WARNING (UK Models only)
The flexible mains lead is supplied connected to a
B.S. 1363
fused plug having a fuse of the correct rating for the set. Should the fuse need to be replaced, use a fuse of the same rating approved by ASTA to
BS 1362
, ie one that carries the
ASA
T
mark.
IF THE PLUG SUPPLIED WITH THIS APPLIANCE IS NOT SUITABLE FOR THE OUTLET SOCKETS IN YOUR HOME, IT SHOULD BE CUT OFF AND AN APPROPRIA TE PLUG FITTED. THE PLUG SEVERED FROM THE MAINS LEAD MUST BE DESTROYED AS A PLUG WITH BARED WIRES IS DANGEROUS IF ENGAGED IN A LIVE SOCKET .
When an alternative type of plug is used, it should be fitted with the correct rating fuse, otherwise the circuit should be protected by the same rating fuse at the distribution board.
UK PLUG W ARNING
LCD PANEL CAUTION
Whilst working on this product, it is not recommended to lay the TV set face down when powered up, as this can result in panel problems. If it is necessary to power up the TV set when face down, the time should be minimised as much as possible.

Note :
• All capacitors are in µF unless otherwise noted.
• pF : µµF 50WV or less are not indicated except for electrolytic types.
• Indication of resistance, which does not have one for rating electrical power, is as follows.
Pitch : 5mm Electrical power rating : 1/4W
• Chip resistors are 1/10W
• All resistors are in ohms. k = 1000 ohms, M = 1000,000 ohms
: nonflammable resistor.
: fusible resistor.
: internal component.
: panel designation or adjustment for repair.
• All variable and adjustable resistors have characteristic curve B, unless otherwise noted.
• All voltages are in Volts.
• Readings are taken with a 10Mohm digital mutimeter.
• Readings are taken with a color bar input signal.
• Voltage variations may be noted due to normal production tolerences.
•: B + bus.
: B - bus.
: RF signal path.
: earth - ground.
: earth - chassis.
