Question about Hitachi 50V500 50 in. HD-Ready LCD Television

2 Answers

Picture is all Red

My 50v500 color changed to a mostly red screen, although it also shows some blue. I changed the Lamp and there was no fix. It does have the pink circle in the middle when I shut if off. Will the light engine alone fix this problem or do I also need a tech to reset the memory?

I don't think it's a prob/with the lamp try something simpler,poss cable connections (dontknow if you've already tried new componet cables/but that's where I would look first. If thats no good poss the color calibration would be a factor.

Re: Picture is all Red

You have a defective light engine and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them about the problem. At first, they will act like they have not heard about this problem but they have. They will then give you the names of some certified dealers in your area. Call one of the dealers to come out and once they diagnois the problem, call Hitachis customer relations department back and let them know. They will all of a sudden know about the problem once a tech has confirmed it...imagine that. Hitachi will call the dealer and once the dealer tells them that it's a defective light engine, Hitachi will send the part directly to the dealer. The dealer should then give you a call and set up a time to come out and install the part.

Now, Hitachi will cover the part regardless if you're still under warranty or not. If your not under warranty, all you should have to pay is for the install. Our install was $400. TV looks brand new! DO NOT let any dealer tell you that you will have to pay $1500 for the part once they get it from Hitachi and if they tell you that, report them to Hitachi immediately! Hitachi is covering the part and all you pay is for the install. Please deal only with Hitachis customer realtions department at the # I listed above. If you deal with the regular customer service department, they wil have you chasing your to speak. Good Luck. It should be pretty cut and dry!

My 50v500 screen has a red screen when the tv is on but no signal. Also, the top of the screen has blue on it. Is this problem just as simple as replacing the lamp? Thank you. Richard Doyle

  1. Perform Memory Initialization. NOTE: You must write down some data values before performing initialize.

  2. Check this status of the picture. It will determine what part need replacement

My Hitachi 50V500A has a large area where the color is turning out to red. Is this a lamp or a complete light engine replacement job?

not the lamp. hitachi knowingly had a defect with the fan not allowing enough air to cool the lamp which has burned the red color lense resulting in the red on your screen. enjoy your new brick thanks to hitachi!

Same problem

The red death as its called.

Very common in the 50v500 and 50v700 series.

it is caused by a blocked filter deep inside the TV, nearly inaccessible.

The LCD panels overheat (red one or blue one) and the light engine needs to be replaced.

You are better off living with it unless you have a warranty.

Sorry it wasn't better news.

If you have the "red" blob in the center of the screen or you have "blue" blobs that show up in random areas of the picture then the only repair is to have a technician replace the optical light engine.
