Question and Answers

Q:

What can cause a Hitachi LCD TV to turn blue?

A:

The fist thing to do is to rule out everything that could cause this that is not the TV. A common problem is that the component cables are not properly installed and you lose a color. If you had the red cable out you might see a bluish greenish picture for instance. Check another source (i.e. DVD, cable box, game system) to make sure it’s on everything that this occurs. If we rule that out then there’ a couple of things I've seen cause this.

This TV would occasionally have heat damage in the light engine and it would distort that one color's brightness to appear like a blob in the center of the screen. This would be irregular but would slowly grow as you kept using it and could eventually take up the whole screen. Another symptom was that the cables that went to the LCD panels inside the engine block would become loose and a whole panel would go missing (you could have lost red). Both these scenarios were usually handled with the replacement of the light engine. There was also a service tip related to the screen being red where a reset was performed but it did not mention a blue screen condition.

Q:

Why does my TV not turn on?

A:

If the TV fails to turn on and the lamp indicator is lit, it is pointing towards a lamp ignition failure. The signal board tells the lamp ballast to fire, the lamp ballast fires and the lamp illuminates. The least common problem is losing the on command to the ballast. The ballast not firing because it is defective is a possible scenario. The ballast fires but the lamp does not light is most common problem. This can be troubleshot but checking the on command and the supply to the ballast but since the lamp is consumable part I would try it first.

Q:

I have a Hitachi 50V500 LCD rear projection TV which is 6 years old and I am seeing bleeding colors in the center of my picture it's not the lamp, what is it?

A:

If it looks like an entire color (red, blue, or green) has been shifted over a little bit then there is a chance that no part is needed, just an adjustment in the service mode by a technician.

Another symptom that can be described as a "bleeding color" is a blotch or haze. Usually, you notice that it has grown over time. It is a discoloration but does not affect the whole screen at first. This is usually a problem with a part called the optical engine. Unfortunately it's not consumer replaceable, you will need a technician to replace it and the cost of the engine itself will be a few hundred dollars.

There's a lot of things that could be causing this symptom, including something that's not in the TV at all. I recommend contacting service for a proper diagnostic if you have any doubt to what your actual problem is.
