Revision 2
White – Carry out as required
Yellow – Carry out as required and whenever the unit comes in for service
 Red – Carry out on all units
Location of Components on the CRT PWB - 66cm and 76cm versions only (the PWB fitted to the 56FW53H does
not have Q5407/Q5408 fitted and is phyusically smaller then this example)
When the avalanche diode is fitted, only four components generally need to be replaced (D735, Q601,
IC705 and C720), this is because it prevents further damage to the circuitry should the power supply be
kept running.  Sharp produce a kit that contains these four items - use the part number

To ensure that excessive HT does not cause further problems, if not previously fitted make sure that an avalanche
diode (D735) is fitted across C720 on the print side of the PWB.  The cathode of the diode should be connected to
the positive side of C720.
