Hi lcaillo,

This TV is showing signs similar to convergence problem but not really. Because in convergence adjustment mode where a cross sits in the middle, I saw both horizontal tilt and vertical tilt on green. My friend told me this happened all of a sudden(TV has been sitting there for ever so can't be loose yoke). Apparently this is not STK chip issue as I don't see dip at the middle on the top or sth.

Have you seen this before and is there a trick(service mode) to adjust it back? Pointer to this kind of information is appreciated(need to save face from my friend lol). How to enter service mode? Thanks!

If it has changed significantly there is a reason. You need to get a service manual to try to do adjustments on a Panasonic. The service mode is not at all intuitive and the liklihood of figuring it out with a few words of advice is very low. Chances are it will not adjust out and will need some repair.

Is about 1 to 1.5 inch(don't remember exactly) tilt significant? I guess so :jiggy:

BTW I found a free service manual for PT-53WX53. Do you know if the skew adjustment in service mode the same as PT-53WX42F?

I'll give it a try to adjust. I agree there should be an issue causing this. BTW I only need to know how to enter service mode. Can you help master lcaillo,

The service manual should detail how to enter the service mode. I do not recall how similar the sets are, but many sets of the same brand are quite similar. I would try it and see if the procedure works for your set.

That much error probably indicates a problem. I would be surprised if you can adjust it out.

 

[ljryjj]

I see. I'll try it and keep you posted.

An interesting variance to the convergence topic, isn't it? :dunno:

Finally got some time at weekend after two months, to put my hands on this TV again. Spent 3 hours in service mode and I was able to adjusted it back. Now the convergence/geometry is near perfect.

 

[lcaillo]

Great! Glad you had success with it.

Thank you lcaillo.

I like the service mode feature of pressing "1" to cycle through all color combinations. So that I could adjust green, then green+red to make a yellow grid, and then plus blue to make the white grid.

Glad it is working for you. Is the service menu hard to use? Where did you find a free copy? I have no luck yet to find one.
