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.
