Our tv just started having a fuzzy image and the auto focus function aborts during the red color alignment. is there a manual alignment I can do to fix it.


What does this fuzzy image look like? Does it have ghosting shadows. Of course it is possible to align red manually from the convergence menu. But first lets confirm that it is indeed a convergence related problem.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

Hi. My Sony Videoscope XBR's Convergence Allignment


I happen to share this same problem. The alignment of the gridlines on the standard convergence panel are completely abnormal, and if I attempt to auto-adjust the TV, it flashes different colors on the sides of the screen , and then turns off the convergence settings.

Pioneer SD-641HD5 red convergence - not chip problem!


Replace Both of your STKs if they are STK392-110s do not go back with them use STK392-180s better ICs, The 110s fall apart and do not hold up.

Red horizonal convergence tilts instead of adjusting evenly.


For your hitachi unit one of the convergence IC is bad along with couple of low value resistance on
the convrgence board.

Good luck

Convergence ICs


the green is half controlled by half of each of the convergence Ics meaning green horizontal is controled along with the red and green vertcal is controlled along with the blue Ics. So if you have replaced both Convergencs ICs the problem is most likely a resistor that is in the green circuit. You will need a schematic to locate which resistors are in the green vertical and horizontal convergence circuit

Red convergence wont move


if the red line is blurry and you have adjusted the screen focus control and does not work then you prob have a bad red CRT or bad red CRT fluid.........

convergence STK have nothing to do with the red being blurry
