I have Hitachi 55hds69 plasma tv that is getting green and red sparkles on the screen. is there adjustment that can be make to correct this?

SOURCE: hitachi 52 projection tv

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.

Issue occurs due to malfuntion of LCD Module matrix. Seeking assistance from a qualified hands on technician adviceable. There are 2 major possibility First LCD module connectors might stained/loosen due to environmental causes such as humidity. Secon important possibility one of the driver Chip on LCD has stopped working. First possibility usually lower cost for repair. A further hands on diagnostic on LCD module will clarify best better.

Good Luck

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

The easy way to fix this: Click 'Menu' on your remote. Then click 'Setup'. Next, you will have to select 'Screen Position Setup'. This will open a screen that allows you to adjust your TV screen position simply by using the arrow keys on your remote. If your TV is anything like mine, this will work.
