Re: I have a Hitachi 50v710

You have a defective light engine and here is what you need to do...we just went through this. You need to call Hitachi's customer relation department at 800-654-7013 and tell them the problems your having and that you think it's a defective light engine. They will initially act like they have no idea what you're talking about but will give you the names of some certified dealers in your area to call. Once you have a tech out from the dealer and they confirm the light engine problem (takes less than a minute) call Hitachis customer relation department back and tell them that a certified tech confirmed the problem. All of a sudden, Hitachi will say they are aware of the probelm...imagine that!

Hitachi will call the dealer and confirm this with them and they they will send the light engine directly to the dealer and Hitachi will cover the cost of the part (around $1500). All you will pay for is the install. Our install was $400...worth it to us since we paid $3600 for this TV 3+ years ago and it's been a great TV.

DO NOT let the dealer tell you that you will have to pay for the part. Hitachi knows about this problem all to well and they are replacing the part for free.. Again, you only pay the install. Please deal only with the customer relations department at the number I listed above. If you deal with their regular customer service people, they will have you chasing your tell. Hitachi customer relations will take care of you! Good Luck!

The screen has a reddish tint to it. Seems like a color issue and not sure what to replace. The picture works fine but everyone is red. Not sure if there is a bulb to replace or what? Any suggestions? This...

You need a simple color adjustment. (Color Calibration)

You don't need to spend money on this. Try it for yourself.

Your main problem is that your color temperature is set to warm.
You need to change temperature to COOL or 6500K depending, on how it is labeled.

You will see improvement, but there is a little more...
Move "Color" DOWN from it's current position (probably at 50) to somewhere between 30 and 40. (Just a couple of clicks above where the color rapidly washes out.)

At this point there will still be slightly unnatural color to skin tones, but all the artificial "sunburn" and blaring red will be gone.

Last (as far as color goes) move the tint 2 to 4 clicks toward green. This added green tint balances the color so that the flesh tones become completely accurate and realistic.

For even better detail, continue your home calibration here:

I think I have a solution involving far less effort. Have you tuned your picture settings? Out of the box, the settings are ok and the presets will do the trick for most. But if you're like myself, you want the best picture possible. Here are my settings:

Have a green tint over 90% ot the center of the screen

I had the same problem with my 60V500A about a year ago. The screen got a red tint in the center and the image was fuzzy in that area. A new lamp didn't solve the problem. I did some checking and found out that the original light engine used in this model had a cooling issue that could cause the light engine to overheat and distort the LCD panels. My warranty had run out more than a year before this happened so I figured I was screwed since the light engine was so expensive. I decided to call Hitachi tech support and see if I could get a discount on the cost of a new light engine since the cooling problem was a known issue for this model TV. I calmly explained to them that I was aware of the cooling issue in the light engine and that I felt like a $4000 TV should last more than two or three years. Tech support gave me the phone number for my local authorized Hitachi service center and I gave them a call. Once the technician confirmed that it was the light engine that was the problem Hitachi sent him a replacement light engine at no cost to me. I was WAY past my warranty period so I still had to pay for the labor to replace the light engine. $300 for labor was a lot cheaper than buying a new light engine or tossing the TV and buying a new one. I have to say that Hitachi earned my respect for admitting there was a problem and doing what was needed to correct the problem more than a year after my warranty had expired.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Green color on Samsung ln-t4042

If the whole screen has this tint problem, there is nothing you can do. It must be repaired. You will need to take it in for service.
