Question about Zenith IQB64W10W 64" Rear Projection Television

1 Answer

Picture is off center, (skewed to the left)

I am proficient in converging the PRO900X and have the Service remote, but I cannot get it to work with the IQB64W10W. Oddly, the internal convergence cross hairs are centered, but the actual image is off center, regardless of source/input.

Adjust the convergence or reset it to factory default. Use only the remote when adjusting convergence. The front controls have no effect.
  1. Press action button to enter MENU.
  2. Navigate to SETUP.
  3. Scroll down to CONVERGE.
  4. Press VOL > to select.
  5. Press CH buttons to navigate up or down.
  7. Press VOL > to select.
  8. If CONVERGENCE ADJ is selected the align Green to Center screen will be displayed.
  9. Use the navigation buttons on the remote control to align the horizontal and vertical green lines on screen, with the cabinet reference marks on top center and left
    center of cabinet.
  10. Press ACTION button to display red center correction screen.
  11. Use the navigation buttons on the remote control to align the red cross with the white cross pattern at the center of the screen. To prevent picture tube damage do not leave test pattern on for an extended period of time.
  12. Press “0” on the remote control keypad to display the BLUE center correction screen, repeat procedure for adjusting blue. If needed press “0” again to return to RED correction screen. An adjusted cross pattern appears white with a minimum of color protrusion.
Remote Control must be in TV mode.

Hitachi 65F59 65-Inch CRT Projection HDTV picture skewed.

The convergence output IC's have failed and need to be replaced. Sometimes when they go biasing resistors burn open also. These are large amplifiers mounted to heat sinks and have as many as 18 pins soldered into the circuit board. Better be handy at desoldering even if it's only the IC's that are bad.

Phillips 43pp92 0217

Sorry to bother you again but I did some research and the chip numbers are STK 392-120 but using STK 392-180 is recommended replacement. If the picture is bowed or skewed any at all then the chips are needed replace both and check if any 6.8 ohm resistors are burned or open. Resistors Can be measured out of circuit with a digital volt-ohm meter. Have you tried the consumer menu and located the convergence adjustments? If it only need touch up you should go there. And the numbers I gave you 062597 must be followed with pressing the status button on the original remote. this goes into the service menu and adjustment to convergence can be made there also if touch up is needed or after you replace the chips Hope this helps

Red convergence is bad.

Hi, you need to change the convergence ICs , STKs: and some resistors,low values; , after changing them, you will have to go into the service mode, to do some adjustments.that's it.

Red convergence is out of alignment

If the mis-convergence is only noticable on the left center and the top and bottom left side of the screen is good, then it sounds more like a pincushion distortion problem rather than a convergence one. Otherwise, you could have a bad pair of convergence IC's or capacitors / solder connection problems. I would doubt that adjusting the service menu would correct this problem, and you could make it much worse by trying. Better have a technican work on it if the picture quality is still good otherwise.

Convergence problem, lower left corner fixed green gun convergence bows upward

You have a componet out of tolerance in the green drive circuits, resistor or capacitor. If you have the service manual you should be able to take some raedings off the test points for the circuit and be able to track it down. I am enclosing a link where you can purchase the service manual for that set for 10.99. They will mail it to you unless you go back to the site and request that they email it to you by clicking on the contact us link. They also offer unlimited free support if you purchase your manual. I am one of their support techs. Hope this helps. Heres the link
