Our hitachi has horizontal lines across the screen

I have a suggestion that will tell you and me exactly what your problem is--Does set have small button on front that says MAGIC FOCUS? If it does press it and after it starts press it again--it will stop the magic focus and bring up the convergence grid on the screen----you will see a grid of lines and just need to look at them----if red or blue is out of place you have a convergence problem--very common on this kind of set.

If set does not have MAGIC FOCUS BUTTON (IT IS ON THE RIGHT OF THE KEYBOARD AND MAY BE RECESSED) You can remove the front speaker grill and the inspection plate behind it----there is a tiny small push button switch on the left front of the circuit boards--it will have blue button--us something not metal (I use a eraser end of a pencil) this will engage the set into the same convergence mode.

You just need to see what the grid looks like--if it is skewed etc--YOU KNOW YOU HAVE A CONVERGENCE PROBLEM.

If it is a convergence problem I CAN TELL YOU WHAT IS INVOLVED TO REPAIR THE SET---it will depend if you can do it yourself or need to have someone do it for you--most of this repair is just getting at a few parts and being able to do good soldering etc.


Try to check to see if you actually have a Convergence trouble or something else--if the lines on the grid are not white--red or blue bowed or out of place anywhere--it is convergence problem.

Seeing is believing and if you see the grid looks bad.


let me know--I am here to help people---I HAVE FIXED HUNDREDS OF HITACHI SETS WITH ALL KINDS OF TROUBLES--CONVERGENCE IS THE MOST COMMON PROBLEM--BY THE WAY: CONFIRM THAT ACTUAL MODEL NUMBER IS 51F500.
