Sony KP-51WS500 - Convergence Issues

post #1 of 13

Thread Starter 
I originally posted this in the wrong section so I'm reposting again here where I hope more people can see it and offer some advise. Thanks.

The convergence on my Sony KP-51WS500 is really out of whack. I have the Service Manual and I've attempted to adjust the course and fine settings (the R/G/B grid and dot patterns) numerous times, but I can't get my changes to save.

Page 39 of the Service Manual says, "Before returning to the service mode, press the "MUTING" + "ENTER" buttons on the remote commander to write the data." I've done this several times, but each time the adjustments that I've made are lost.

I do get the "write" confirmation when I press the MUTING+ENTER buttons on the remote. (Thanks 'hammerdwn' for the suggestion)

Is it possible that the red, green & blue CRTs in this TV are so physically out of alignment that they cannot be aligned using the convergence tools in the service mode?

Any ideas, advise or suggestions will be greatly appreciated. Thanks!

Did you also save the changes to the flash focus memory? Do the normal save and hit FF ...

It sounds like it's time for a service technician's visit. You might need a physical allignment of the tubes (not recommended for DIY unless you really know what you are doing, and have some CRT tube adjustment experience - which may not be enough).

I wouldn't attempt to adjust the CRTs myself. Now I just have to decide if I want to invest hundreds into this set or put it on the curb! Thanks for the reply.

Also keep in mind the convergence is wide-mode dependent (full, wide, zoom) and I'm not sure about input resolution dependent. I don't have my service manual in front of me to verify and I'm going off the 510 not the 500.

Make sure you do not do this when the TV is fed 1080, at least on the 510. It will hose up the whole TV.

To save a new FF setting while in the SM, you can only do it in 480i "full" mode NOT 1080i "full" mode!!

This pertains to the question I have. The 510's have a Manual Convergence feature from the user menu whereas the 500's do not. Both offer the Flash Focus (Auto Convergence) feature as well.

Will the Flash Focus hose-up the Manual Convergence? If I set the convergence manually in the service menu and save it, will the Flash Focus recall those settings at that point?

In terms of modes, if I set the convergence manually for each mode (480i/p, 1080i) and save it, will the Flash Focus work appropriately and recall the setup for each mode (or does it only store one position/mode)?

If Flash Focus only stores one mode, wouldn't saving the 1080i calibration take care of the 480i/p? Or, does Flash Focus only operate in 480i/p?

Overall, I'm just curious if the 510's Manual Convergence assists or hinders the functionality of the Flash Focus (and makes it more valuable than the 500 series). I'm sure a lot of this has already been answered elsewhere, but I thought this would offer some concise clarification. Thanks!

Yes, flash focus will change anything you did with manual convergence. Typically you would do flash focus and then make any finer tweaks with the manual convergence.

If you make convergence changes in the service menu you will lose all of those changes as well if you press flash focus. To prevent this, when done making changes in the service menu you need to re-register flash focus.

And yes flash focus does save all settings for all wide modes.

Perhaps you are hitting the wrong enter button. It is not the one in the center of the remote, but the one at the bottom right quadrant marked ENT. if memory serves. Easy to miss. Confirmation that your new data is saved when the green "write" turns to red.

Why is this? When doing my convergence, I think a 1080 signal was being fed. I didn't have any problems with the flash focus and the picture seems great. Am I missing something?

Not sure as I have not tried it to find out, but in the reading I've done many people said not to do it and I read a few instances where people had and the TV went dead. The service manual also says not to do this.

I have the Sony KP-57WS520. I'm not a big fan of Flash Focus - I do a manual convergence in the service menu. Actually, since my overscan is just over 2.5% my Flash Focus is disabled...evidently it doesn't work when you get under 4%.
