I had whole redish/pink 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!

1. Enter the I2C Service Menu, be sure the power is OFF.
2. On the front control panel, press and hold the INPUT button.
3. Then press the POWER button for two seconds.
1. You may keep the INPUT button depressed until you see the OSD with the Service Menu displayed.
2. If you don't see the service menu, please repeat Process making sure you wait until the Power blinking LED stops.
3. 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.


4. After the Memory initialize operation has finished (10~15 sec, the channel will revert to CH 3.) the pink image symptom should be fixed.


5. 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.


6. Exit I2C menu. Press exit repeatedly until you go back to the normal picture.


7. 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

About two years ago, I had a small red blur in the middle of the screen. That red blur is now all over my screen. I called Hitachi and they said that there's nothing they can do about it because it's almost 4 years old and the warranty has expired. I called a repair shop and they said that it may be a light engine problem and it will cost about $1300 to repair. Might as well get a new TV for that. I did some research and found out that this is a common problem and that you need to be persisting when calling Hitachi and speak to a supervisor. The supervisor said that if a repair person confirms that it's a light engine problem, that they will send the part FREE OF CHARGE (just gotta pay for labor). They will only send a replacement once.

Your light engine is shot. I have the same problem with mine. Except now in addition to the red I have blue that is also showing up.

Blurred picture and it's also dark rear projection zenith Z52Z95D


I'd get the lamp replaced for sure. If it has a ballast - change that at the same time. However, a Zenith repair center should be able to tell you whether it's worth doing or not.

The image is getting blurred


Hi

The camera may have moved when the picture was taken. Try steadily squeezing the button intead of a quick press.

2.Try using a tripod, this could fix the blurred images.

3. faster shutter speed will be needed if you need to hold the camera, and cannot use a tripod.

4. Main reason for the lines could be that the subject is to bright.
A vertical bar of light(red, purple) appears on the LCD monitor/ in the viewfinder This is a normal occurrence in devices containing CCDs (Digital Cameras) and does not mean a malfunction. (This red bar of light will not be recorded when shooting still photos, but it will be recorded when shooting
movies.)

Solution to the last point would be to try and switch of the flash if it is in use. Turn the ISO setting (50, 100, 200) to a lower one as well.

Hope that helps.

Blur Image


Hi there

If it is a DLP Projector it could be the Packlight Pipe Module that needs repairs.

Basically this part has 4 small mirrors facing each other and this normally happens when one of the mirrors come loose.

Very cheap to repair

Trouble with the red cannon


Hello, is the blue blur the only blue on the screen? The reason I ask is because the vertical defection to the blue CRT might be going bad and producing a blue line across the screen. I doubt that it is a convergence problem, but it may also be a magnetism problem and you may need to degauss your set with a degaussing coil (check ebay for specials on this device). I have seen a lot of the projection TVs end up needing to be demagnetized (degaussed). Try degaussing it first and then look at the possibility of a vertical deflection problem and then possibly a convergence issue.
