Hitachi 53UWX Can't Post
Hello,



I have a hitachi 53 inch tv. It is about 3 years old. On the left side of the TV the image has a green shadow. It seams like the red and blue are on top of each other, and the green is shifted. It is bad on the left side, and diminishes as u get close to the middle of the screen, and then it is fine form the middle to the right side of the screen.



Any suggestions on where to start? I am an engineer with all the testing equipment that i may need.



Thanks for the help.

Jason

sounds like the convergence is off. If it can't be adjusted you will need to replace the 3 convergence amps. STK-something

Seems a little strange, I would think that if the convergence is messed up, that it would affect the whole TV, instead of just the left side.



How do I verify that I need to replace the amps, and where would i get them from ?

I did a lot of reading, and found that there tends to be some cold solder joints on the amplifires. So I took the convergance board up to my lab, resoldered the 18 pins of the 2 amplifiers. Now it seems to be fine.



How do i get into the manual convergence menu ? I read of poeple bringing up a grid, I have not been able to find such a thing anywhere.



The picture looks good, but its a little fuzzy, especially the text.



Thanks,



Jason
