Hey, I have a Hitachi 52" Ultravision digital TV model 50V500. The picture has gone all yellow and red. Almost no blue. Not really any green either. Any idea what part I may need to replace?

SOURCE: HITACHI ULTRAVISION 50v500

the problem is most likely a defective light engine, it is a very commen problem with these tvs. hitachi is not very forthcoming with information or help unless your still under warrenty, i have talked with a few people about this and have found a lawyer starting a class action suit, if interested here is a segment of another conversation with all the info to get you started. " let other Hitachi TV owners know about the Class Action Lawsuit against Hitachi regarding the defective optical light engine. They need to call the Law Firm in Dallas Texas, HORP & B, that you mentioned is handling the case and talk to Victor @ 1-877-308-7900. They are taking documentation and cases regarding this suit and people that feel like they have been treated unfairly wherein Hitachi denied sending them a new optical light engine @ n/c need to call and state their case. "
good luck with your problems

First of all sorry for delay.
can you provide a image of yello shadow.I believe it seems to be technically say "ghost image"
If it is ghost image we can try by entering SERVICE Menu and adjust RGB level of the light engine.

Good luck

You may need to go into your menu settings on the TV, and adjust the RGB colour settings (if it has that option). All colour setting for Red, Green, and Blue (RGB) should be level. Not all TV's allow this adjustment though.
The other thing is that the ribbon cable to the back of the actual screen panel may have come detached just enough to lose some of its signal quality. Although these things are digital, it's still possible for a bad contact to do strange things.
Hope that helps, good luck :)

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.

Hi:
The only way to repair this is to replace the optics engine assembly, Light engines are rather cheap these days, try looking on www.tristatemodule.com for a new or refurbished one.

Hitachi 50V500, no picture ,sounds for about 15 sec.then goes off


Hello,

I would try to re-seat the lamp. Pull the lamp out, check it to see if it may have gone bad again, then put it back in to make sure the contacts are connected. Before applying power, unplug the TV for 5 minute, and then plug in/turn it on.

Most lamps, if bad from the factory, will go out within 3 months of use. It does happen, and happens more often than you would think.

Try this, and see what happens. Good luck.

Picture is yellow and green


Your missing the red drive on the set. Its most likly the picture tube. Its a possibility that the red drive circuit could be not working so the best thing to do is take off the gree picture tube socket and put the green board on the red tube. Of course do all this when the set is unplugged. if you have no tv experience. its not a good idea to be messing around inside of these sets.
