I was recently given this tv, and after setting it up I have noticed many geometry issues. It looks like a previous owner has been in the service menu. I found a service manual online that lists default values for some of the settings in the service menu and this has made it much better.  There are a few that weren't listed in the manual such as csaw, tcnr, and bcnr. I'm not sure what they do or what they should be set at. Is there anyway to find a complete set of default values for the service menu? I'm not too keen on just adjusting these and risking the possibility of making it worse or breaking the tv.

This is the best I could quickly find searching around:

CSAW = vertical Sawtooth adjustment? (geometry)

TCNR BCNR = Top corner/bottom corner adjustment (geometry)

Speaking of geometry, are these things magnets?, if yes, do they help correcting TV geometry?

Not sure. But if you have a pin or paper clip, you can find out. wink.gif

Secondly, I'd attempt geometry adjustments from the service menu before messing around on the inside of the set.

They're pieces of ferrite with very light magnetism but I don't know if they are magnetized when installed or just pick it up during use. Yeah you can probably mess up your TV good messing around with those not knowing what you're doing. biggrin.gif

I used a few from a scrap TV to improve some off-color corners on my CRT, not wanting to open the beast up I placed them on the front plastic case near that part of the tube. Shower curtain magnets were too strong.
