Re: hitachi 46

Your TV most likely has one or more possible problems.

Problem #1: 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.
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 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.

Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from that includes replacement coolant, photos. instructions, etc.

Re: hitachi 46

You have a convergence problem. Probably the convergence IC's. Usually they are located on a large silver finned heat sink. There are usually two or three and they start with STK in the number. Common #'s are stk392-010 or STK4****. They need to be replaced.

We have a 46" Hitachi TV that suddenly after the cable man hooked up a new receiver box has gone funky! The top left of the screen is wavy down about a third of the screen and the wording is...

What you just described is a convergence issue, Now most tv's have a auto focus button on them or the remote try giving that a push (if your tv has it) I cannot go by the model above because fixya has categorization errors or people select the wrong tv.

But this is a convergence issue if the focus button does not take care of it your going to need repair.

thanks for using , please do leave positive feedback or ratings, Thanks

There is a wave in the picture only in the upper left hand 1/4 or the screen. The rest of the screen is sharp. You get the colors separated and thus double image.

Projection TV sets have several common problems listed below.

Problem #1) Convergence


  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.
Example Photo:
Problem #2 CRT Fluid has clouded over.


  • Dull Video, Washed out
  • White/Bright looking video
  • Halos around objects
  • Red/Orange looking

Getting double images on screen like outlines on images

Your TV has a failure of its convergence output ICs and perhaps some of the convergence circuit's other associated parts. The part numbers for the ICs are on the IC face. They can be purchased thru Hitachi or online at MCM Electronics.
