Hi and welcome to FixYa,

Just like in small TVs except multiply it by 3. There would be a squarish PCB at the rear of the CRTs/tubes containing the color drive. Often problems are cold solder issues and/or loose connection. Worst case scenario is a defective blue tube.

I would suggest the best/initial course of action is to get hold of a service manual or at least a schematic diagram with voltage readings and follow checklist/diagnostic procedure.

Good luck and kthank you for using FixYa.

You did not say what type of TV you have. A flat screen plasma, LCD or a CRT (older picture tube type)? The fact that you can get a black and white picture just about rules out a problem with the plasma, LCD or picture tube display. The fact that a color picture is only displayed in shades of blue and green points to a lack of red. This can be as simple as adjusting the tint, or can be caused by a defective red video stage, usually the output stage, or a dead color oscillator. In the latter two cases it is a circuit problem and would require repairs. Service on TV sets as you may know is no longer inexpensive. Find the tint adjustment first, the kids may have gotten it way off. Put the bar in the middle, or if you have a reset option which returns all picture settings to the levels set at the factory try that.

Yellow to green tent screen to hitachi tv 42v715


You have some reason to believe it will not?

Some history for you---several years ago Hitachi began along with others to have issues with the optical light engines.

With a mix of high heat from a lamp into the engine (it has a blue,green and red section inside---guess what? BLUE is the first place that gets the heat and is damaged----minus blue and you have red and green which equals YELLOW.

Several of their sets made about 6 years ago (research 50v500) had exact same issues and were settled in a class action lawsuit.

The issue can but does not always affect the entire screen.

The question really is: This set really worth the part and labor cost for the repair?

On that earlier model I replaced under warranty over 40 of the engines. Also Sony and others have had similar issues some of which were settled in court.

HOPE IT WORKS OUT FOR YOU.

Green bulb-or lamp on ultravision hitachi 57uwx20b does not work how much to replace?


On a projection television you will have to replace all three(red,blue,green) projection guns in a matched set, the reason is if you replace just the green gun, your picture will be over saturated with green light making your picture look green,because the new gun will be alot brighter than the red and blue guns.
With that said, repair will cost approx.$400+, I've heard up to$600. Good luck !

inside the light engine there is a red a green and a blue glass color filter.The heat from the lamp causes the color to burn off the glass.You need new filters .One is red one is blue and one is green.The lcd itself doesnt make the color,it is a black and white device.The colr comes from light shining through colored glass

Looks like 3D tv


Try doing a calibration. Projection TVs work with 3 picture tubes (Red, Green, Blue). The Red may be off to one side causing the hues.

The manual is available here for instructions on how to perform calibration:
