Revision 3
GF Models
The table below details the different part numbers for IC1002. Note that this IC can either be an EPROM or a
MTP. An EPROM has a small window in its top to enable the IC to be erased by ultra-violet light. A MTP does
not have this window and normally works at 3.3V.
Model CRT EPROM Type EPROM Part Number
66GF63H Philips EPROM CH-IX1711CJH1E
66GF63H Thomson MTP CH-IX1711CJH1M
66GF64H Philips EPROM CH-IX1711CJH0
76GF63H Philips MTP CH-IX1841CJH7
76GF64H Philips EPROM CH-IX1664CJHAE
76GF64H Philips MTP CH-IX1664CJHAM
Note 2 - Second NVM Fitting
Some sets use a second NVM, designated IC1004 to store teletext page information and some audio data in the
case of Dolby Pro-logic models. Sets that have the second NVM fitted are:
66FW54H 76FW54H 66GF64H 76GF63H 76GF64H
The part number for this device is the same as IC1003.
Note 3 IC1801 Types
IC1801 is the cathode drive amplifier mounted on the CRT base PWB.
Depending upon the chassis type, the CDA IC can be one of three types as listed below:
IC Type Sharp Part Number Comment
TEA5101A RH-IX1416BMZZ All FW and some GF
STV5109 RH-IX1803BMZZ Some GF and all HW models
TDA6019JF RH-IX1833BMZZ Late 56FW53H models
These IC are not interchangeable.
Note 4 – IC801 Types
IC801 can be one of two types. It is either a 3120 or 3130, and they are not interchangeable. The part number
for the VDP3120C2 is RH-IX1688BMN2, the part number for the VDP3130Y is RH-IX1858BMZZ. The 3130 are
fitted in all HW models and some later FW and GF models.
Some patterning can occur when fitting later revisions of the VDP3120C2 to earlier chassis versions. In this
situation remove C824, which is connected from pin 33 of IC801 to ground.
