    Could be the converter going bad.It sounds like a tracking issue. What do you have hooked up when this happens?

Ok, I own the exact same set--it uses a Vertical output IC located near the front of the main board number on it is LA7638--cheap part.
if you pull off the front speaker grill and remove the inspection plate you will see it almost dead center and a little to the left screwed into a small metal plate with fins--that is a heat sink--lots of these sets had or developed bad solder connections on the pins of this ic---the way I found mine was to remove the speaker grill and inspection plate and with a non metal plastic handle from a screwdriver tapped on the heatsink when the set acted up--if it clears up when you tap on it you have bad solder connections on the IC---if I remember it has 13 pins---with the trouble to get the board out to solder it up I just replaced it with a new one--the part can be purchased for less then 5 dollars at most electronics parts dealers or on the internet---My other Hitachi is a 1991 60 inch model and it has never given me any problems--by the way the 50 in the model number means it is a 50 inch set.
If this helps you give me a vote here--I do this for free--good luck.

I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.

Your TV is at protection mode. It mean there's problem on it. The indicator provide your information that he detected short circuit or fault circuit.

While in Vertical Your problem will one horizontal line if the IC short circuit a call for protection circuit. And Also The Convergence circuit will make power interruption also.

If the picture is jumping from top to bottom this is a vertical issue. The common cause on older Hitacjis is loose connections on the vertical output IC.
