Does there exist a manual for Hitachi Natura Tv, progressive scan on net?

Please intimate exact model number of your Hitachi TV to look for user manual. Model number would be written on sticker pasted at back of TV.

TV has fuzzy piture, all colors, but contrast is awful

I think you'd have to look at how much a comparable set would cost. I know that flat screen sets are coming down in price.

One thing you could try is to adjust the focus control although if it just went all of a sudden, then this may not help. There are two controls on the flyback transformer. Follow the thick red wire from the top of the picture tube down to the transformer that it's connected to on the circuit board. There will be two controls, the upper one being focus (marked with an "f" or the word focus). Try adjusting this while watching the picture. A mirror may be helpful. At the same time, be very careful what you touch in there, any metal part could have high voltage on it. As long as you are just touching plastic parts you should be ok. A good rule of thumb is to keep one hand behind your back as you work so as you don't inadvertantly ground yourself to the chassis while touching something with a high voltage on it.

If this scares you a little perhaps it's worth taking the set to a shop for an estimate.

My telly comes on then goes off please help me!!!!!!!!!!!!!

Here is my suggestion. You are having a problem with one or more solder connections on the main board. What is happening is when they warm up the solder separates from the other words not enough solder. If you can find the spot- solder it (them) and you are home free. If that's not it, then it may be one of the IC componets is bad.--Hope this helps-Marilyn (used to own electronics store that did repairs :-)

You likely have a fuse bad on one of the supplies to the convergence output IC's.  check EP96 and EP97.

Hitachi 43FDX01B Green Line Not Alligned

If you slap the set on the side and the colors shift and dont line up, it is most likely that one of your convergence IC's has cracked solder joints. It is also possible that the IC has burned out. The convergence IC's will have to be resoldered and possibly replaced, and that should be done by someone with experience in repairing and realigning convergence circuits in projection TV's.

Picture fuzzy

I would suggest to unplug the tv from the wall for about 15 minutes and then plug it back in,and turn it on,this should reset the microprocessor and realign the colors back to normal.let Us know how it goes and if you need more help.
