You will go back & forth till its done & the edges will NEVER
be perfect.
BTW its easier to lean over the set than use a mirror IF your
arms are long enough........

The black blob is probably in the blanking circuit. I have
seen something like it a few times but dont remember
the brand or anything else.

Yes, I first did the convergence with too much contrast, picture seemed washed out, so I backed out the contrast a little and thats when the color lines appeared. I believe that both my 19'' hybrid and this one suffers from the same problem : bad convergence. I thought that I did a good job on them both, but on further examination it's not that great, and I notice a lot of color fringing on both of them. Will put more effort on that.

As for the blob, is it a dangerous problem? Could something blow and damage something else along with it?

Edit : Also I would like to know if all the dynamic convergence pot are suppose to turn smoothly...some do and some need a little convincing to turn. Could dirty pots affect the convergence (much like dirty volume pot can create some scratching and distortion?)

Got this to clean the pots do you think it will do the job ? : http://www.mgchemicals.com/products/...-cleaner-401b/ . I know its desing exacly for that but just wanted to get opinion on that stuff before using it.

thanks!
