Sounds like one of the transistors attached to a heat sink shorted out.
you will need to test each one with the tv unplugged.
set the digital meter on diode.
it`s not easy to explain the rest, sorry.

I know these models came out around 2001, and I'm afraid that the problem sounds like it is related to the bulb going bad.

This article outlines how many TVs from around the turn of the century have had similar problems to yours.

I know bulb replacement is an option. You may want to call around to TV repair shops and see what your options are. In the end, though, it may be time to start saving up for a new TV.

Hitachi TV, has red ghost lines outlining image on screen! Help!


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 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.


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 www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Hitachi hdtv flat panel tv no soundand no picture


Most of the case horizontal output transister failure cause these type of problems. Additionally flyback transformer failure also leads same problem but it depends upon aging of the tv. Whatever it is it could be fixed by service Technician only.

My tv sucks help me


Ryan, this sounds as if the green CRT has gone out in this set. You might want to double check the warranty of your television as this set might have a lifetime warranty on the CRT's. If you cannot find the warranty info on your set, call 1-800-448-2244 for further assistance

Hitachi 43UWX10B No Picture No Sound


Check the stand-by circuit to the main pcb for the keyboard control. If no voltage present, check the 5v regulator in the main supply. If you are not seeing the LED on your supply up, it's likely you do not have the 5v stand-by.
