Red and blue screen on Hitachi 50v500

I have a primarily red screen with some blue once in a while and a fuzzy look to the entire picture.  This happened overnight after 4 years of having the TV.  I called Hitachi and they mentioned a light engine, which I got and nothing new happened.  No fix and a stupid light engine!  :(

I had whole redish/pinkish screen on my 50v500 starting a few days ago, then I read through each of the threads on this site for the samilar problems on my model. I found TVtechmaniac's solution (pasted below) solved my problem. Thank you TVtechmaniac!

Enter the I2C Service Menu, be sure the power is OFF.
1. On the front control panel, press and hold the INPUT button.
2. Then press the POWER button for two seconds.
3. You may keep the INPUT button depressed until you see the OSD with the Service Menu displayed.
4. If you don't see the service menu, please repeat Process making sure you wait until the Power blinking LED stops.
5. Execute the Memory Initialize operation after the adjustment values have been written on a sheet of paper. Highlight “MEMORY INTI”, arrow to the right and hold the button to the right (approx 5 sec.) until a check mark appears in the box. This activates the Memory Initialization.

6. After the Memory initialize operation has finished (10~15 sec, the channel will revert to CH 3.) the pink image symptom should be fixed.
7. Write back the adjustment values from your notes to their respective adjustment parameters in the adjustment mode. (In other words, set the Data Values back to the the Data values written down before the Memory Initialization procedure). NOTE: Make sure the SELECT Button is pressed on remote after every change to the values. Failure to do so will result in the data values not being changed.
8. Exit I2C menu. Press exit repeatedly until you go back to the normal picture.
9. Turn the set off-on and Confirm the picture remains in a good condition.
BE SURE TO COPY DOWN DATA SETTINGS BEFORE INITIALIZING I2C SETTINGS

So is it not the bulb when you get a redish bluish screen

I saw a similar procedure but first you have to set the input for an unused one... maybe ANT2 or video2, video3, video4, or whatever is not currently hooked in to any working input sources, then pwer off and try the 12C menu procedure..

Red tint to screen


If the model is a 50v500 the real question should be does the set have a red oval area in the middle of the screen (entire screen not red)---if the entire screen is red you have a chance---it has a red oval area and it needs a new optical light engine----you will have options also but limited if that is the case.

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

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.

Hitachi 50v500 blueing problem


I am not expert but before you go to a lot of trouble, read all of the post on the infamous "red cloud", "red blob" and "blue streaking". In evey case, it appeared that the light engine was the problem. We just had our light engine replaced and the TV looks perfect. We dealt only with Hitachis Customer Relations Department 800-654-7013. You will have to have a certified tech come out and diagnos the problem. Hitachi will then call and verify, with the dealer, that the problem is a defective light engine and will send out a brand new one.

We were told the part cost around $1500 (Hitachi covers that) however, they will ask you to pay for the install. Our install cost $400. Worth is to us as we paid $3600 for this set 3+ years ago and we have loved this TV. When you first call Hitchi, they will act like they've never heard of this problem but they will give you names of certified techs in your area. Once the tech confirms that it's the light engine, Hitachi will own up to the problem and send out the part.

You really should only deal with Customer Relations ( I listed their 800 number above as you will be chasing your tail so to speak with their regular customer service department. Good Luck!

TV Problem


It is a failure in the light engine itself. You will need to have it replaced. Here is a link to that rather costly part. http://www.partstore.com/Part/Hitachi+Ltd/Hitachi/50V500/Hitachi+Ltd/Hitachi/UX22201D/New.aspx
