Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video

Red and blue streaks across the screen top and bottom

The Convergence Amp IC's are bad. You should call a good TV Tech for this repair.

Hitachi 46F500 and there is a blue curved bar

Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

The picture is blurry. does anyone have a solution to this or has anyone had a similar problem.

I have a blurry screen and the top of it the picture is curved a bit. I was told to adjust the focus knob but I don't know where that is in the back of the TV. I took off the back and couldn't find it. I also tried to adjust the manual convergence and the red would not adjust only the blue would align. Any suggestions.
