WE have a sony wide screen projection TV and just started seeing a blurred picture. We've unplugged the cable and the problem still exist

Hello; Look carefully at images on the screen, Especially WHITE lettering. If there is a color like red green or blue to the edge of the letters. If there is , this is likely a failure in the convergence circuits due to a bad " Power Pack" integrated circuit. These are generally not user repairable problems that can cost $3 to $7 dollars. Probably time for a new set. John

Hitachi 50v500, we just put in a new lamp, now the picture on the screen is slightly doubled, what do I do?

Here is what I suggest----look at lettering and or put the mode to 4X3 which is smaller left and right.

Look at the edges of that picture or lettering on screen---this model sometimes has a ghosting where images have a slight shadow, like with rabbit ears.

If this is the case there is a way with the remote to CORRECT IT.

I have the information--confirm if slight ghosting around letters--it can be white or any color.

I have seen this before.

50V500 ONLY
GHOST: May be described as "Out of Convergence" but ghost is still attached to main image.
A "ghost image" appearing to the left or right of images in the picture. Can be varying shades of a primary color (red, green, or blue) as well as gray. Can easily be seen in the 4 x 3 mode, at the edges of the picture.

To correct the problem, please do as follows:
  1. Access I2C Menu. (See page 57 of the Service Manual).
  1. To enter the I2C Service Menu, with power off, (on the front control panel) press and hold the INPUT button. Then press the POWER button for two seconds. The following Service Menu will appear.

  • Be sure to press SELECT after each change to SAVE the new Data.

  1. Using the Remote Control joy stick, scroll down to next page (see Figure 2) until LCD ADJUST is highlighted.
03b_ghost_image02.gif Figure 2
  1. Move the joy stick to the right to cursor right once. The next page will appear with the word GHOST highlighted.
  2. Cursor right again, and a white screen will appear with a BLACK SQUARE in the center, as in Figure 3. You will see LCD ADJUST, followed by “SHP” and a number (value).
Figure 3

  1. If the unit is out of adjustment, you will see a gray ghost on either side of the black square. Move the joystick to the right or to the left until the ghost disappears. The number values will change up or down.
    • If the ghost adjustment is off with a lower value, there will be a ghost to the left of the square.
    • If the ghost adjustment is off with a higher value, there will be a ghost to the right of the square.
  2. Once you get the square to look good without ghosts, press "SELECT" to save any data values that have been changed.
  3. Press the "EXIT" button three times to return to normal picture.
  4. Adjustment is completed
