Casio TV-8E tiny portable LCD TV

[Peter]

I've been given this device because it's faulty. It's fully functional,
except that there is no sound, only loud hiss like an open mute. I
suspect some kind of IF/detector fault. I have no details about the
history of the fault.

Does anyone know where I can get a circuit for this device, or failing
that, a data sheet for a Mitsubishi M51348FP video/sound chip? I've
googled to no avail, plenty of links, but none leading to an actual data
sheet.

Thanks, Peter

I've been given a Casio TV-8E tiny portable LCD TV, with a "no sound"
problem, but with no other history. It is otherwise completely
functional.

I've just realised that it is fitted with 6.5Mhz ceramic filters in the
audio IF, which probably means it was originally from overseas. The
sound IF chip is a Mitsubishi M51348FP.

Does anyone know where I can get a couple of suitable 5.5Mhz ceramic
filters, retail, in Melbourne?

Thanks, Peter
