Did you try to do a hard reset to bring up your convergence option. Its been awhile but I think you have to unplug your unit for 24 hours . Then your convergence option will come back up.

R56w36 convergence problem. color misaligned. Ghosts.


Dear Sir:

Thank you for contacting fixya.

Please follow the steps below.


green is fixed so you have to move red and blue to green.
by using the remote you may find a simple converge function and open this and using arrow keys move the blue or red first to center of screen, repeat for other color you should see the lines moving toward a a white center point.

if the lines do not move with remote try manual ...menu on the set. if still no movement you have a problem on the convergence board and need a tech to fix.

A service manual will explain complex convergence to the detail .
but this might take hours to get it right.

Please feel free to get back to me If you need any further assistance.
Regards,
Mohammed.

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.

I stumbled across a tutorial on fixing the convergence for my Sony KP-46WT510 a while ago, and now I can't find it again! Does anyone know where I can find that tutorial or one similar to it? We've been...


Here is a walk through on how to set your convergence.

A quick and easy way to try and let the TV realign the convergence try this...

1) Turn on the TV and tune to a channel and let it warm up for about a half an hour to let everything settle into its normal operating mode.

2) Press the Flash Focus button on the original TV remote. A cross pattern will show on the screen and the process is complete when the cross turns white and the TV returns to the program you were watching.

3) Do not press any other buttons until this process has completed.

If this does not adjust it enough you can adjust the convergence manually as follows:

1) Press the menu button on the original TV remote.

2) Use the arrow keys on the remote to highlight setup and press + button to select.

3) Use arrow keys to select convergence and press + button to select.

4) A pattern of white crosses appears, with a yellow [ ] around one of the
crosses. Aligned crosses (which do not need adjustment) look white and
have little or no red or blue showing. Crosses that are not aligned show
red or blue shades beyond their edges.

5) Use the arrow keys to move the [ ] to a cross that is not aligned. ***Note: start with crosses in the middle and work outward ****
*** TIP: Set the alignment while about 5 feet from TV for better results ****

6) Press the + button to select the cross and the [ ] will turn red indicating it is ready to adjust the Red convergence.

7) Use the arrow keys to move the red cross on top of the white one or at least as close as you can get it.

8) Once the Red is aligned press the + key again and the [ ] will turn blue. This indicates it is now ready to adjust the blue convergence.

9) Use the arrow keys to move the blue cross on top of the white one or at least as close as you can get it.

10) Once you have aligned the blue cross press the + button again and the [ ] should turn yellow.

11) Repeat steps 5 through 10 until all the crosses are aligned. To exit back to regular programming press the menu button on the remote.

JVC AV56-WP74 Convergence problem


Hello saduchan,

I think that your ICs are ok, What you need to perform is what is called dynamic convergence, This involves using the internal convergence controls to align the outer edges of the screen. I am assuming that the center of the screen is ok? it's just the edges which are misaligned, right? Now for the bad news, this task is not easy in fact the job takes a pro about 6 to 12 hours to do it right. I think you should have a qualified TV technician attempt the static convergence setup followed by the dynamic convergence setup.

I hope this helps,

Thank you,

T.V. Convergence


John, im sorry to have to tell you, you have the normal convergence break down, and any adjustment is not going to fix the problem. The Convergence ICs are bad in this set, and both should be replaced at once, as you do not want to pay another repair price 6 months down the road. In these sets there are no user replaceable parts, unless you know how to work on solid state printed circuit boards and understand about the TV safety factors involved. Good Luck Please do not forget to rate this thread.
