Normallly, if the format button on the remote for the television does not achieve the desired affect, then, a cable box or a satelite box is where the change needs to be made. For example: A Motorola Cable box needs to be set up to go to a wide screen when an analog signal is detected. It's difficult to determine the repair without knowing the hook up of the peripherals. Hope this helps.

SOURCE: Hitachi 43VWX10B Rear Projection Television - color adjustment problem

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

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.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

SOURCE: Aspect Ratio or Input Issue

Not sure but you might be confusing your aspect selection on your DVR with aspect selections on the tv itself. Make sure you use your hitachi remote & check all available aspect ratios. Find one that suits u best

Hitachi 43FWX20B


I have a similar pblm. But your first step is to power on with tv's button. Look into the back through holes and look for 4 green and 1 red LEDs lit. If not there are 3 fuses on the power supply board.Fuses can be easily changed.
next step call service.
