Subject: [TechAssist] Panasonic CT-36D30B No Audio
Hi Guys, I don`t have any audio (RF or AV) on this Pan. CT36D30B, I also
don`t have a schematic for it so I`m fishing for tips until I can get
the print, the
audio chip IC2302 (AN5272) has 23.8 volts on pin 10 (Vcc) but no audio
going in, I get low audio across C2211 and normal audio across C3020 &
3022 but it`s
impossible to trace out to see where it goes (or doesn`t go). I re-set
the eprom
by holding down action/power and the display says MTS-OK, Pip-OK but
Sound,AVSW, & Comb come up with 2 dashes after the words, ie; Sound--
I`m assuming this just means the set has recognized an audio problem???
Only
get about 3 Panasonics a year here so I`m not familiar with them, any
tips
on this problem, tia, Larry E
