See this excerpt from a previous post:
Hitachi HC3041-S Comb Filter Info
If you need to replace the comb filter in the 50UX14B (and several
other models) you will order part #2375401, the bag will say
2375401 but the comb filter in the bag will be marked 2375403. DON`T
send it back because you`ll just get the same part again. The
instruction sheet inside the bag is useless because of the lousy
translation to English, and the mod sheet from Hitachi is also
incorrect and confusing. The correct modification is actually very
simple.
When you remove the original HC3041-S pn 2375401 from your
customers set, remove the bottom shield and unsolder the 8 pin smd IC
(it`s marked 3108S on the IC). You have to install this 8 pin IC into
the "NEW" comb filter HC3041, part# 2375403. The "new" replacement
does NOT have this 8 pin IC in it but the board is screened and
pre-soldered for it, If you fail to install this IC in the replacement
you will have audio,but a very faint blue screen with no video.
