Folks,

Can anybody point me in the right direction?

My daughter has a Hitachi model C1719T TV receiver with a problem. Nothing
appears on the screen - it remains completely black. There's no sound
either. I don't know if this screen has a cold cathode (do you get such TV
tubes?), but I can't see any
heater coming on, and I can't find any voltage around the tube base. The
two numbers on this Philips tube are : A41EAM11X01 / TL2D063401. The set
generates UHT, because I hear it whistle momentarily when the power is
switched off.

Although I fixed my own TV several years ago (thanks to a Canadian guy
called Sam - can't remember his surname - who was a regular contributor to
the group!), I don't know much outside of the theory of TV's, and when I
look at the board, I don't know enough to recognise where the various
circuit elements are - and I don't have a
schematic for it.

With the back of the board towards me and the components on the top, the
mains cable comes in on the left side, with a fuse just beside it (not
blown), but I can't even find the rectifier. Is it a 4-pin chip, or does it
use discrete diodes? Is it near to the mains cable and the fuse? It would
make sense!

Any pointers will be appreciated.

Thanks,

Mike.
