Okay, I just picked this one up earlier today very cheap. It is a rather standard Samsung CRT, 480i, 480p and 1080i only, no DVI. I've googled, poked around several places, and searched this forum but can find no indication of a service manual available anywhere. Although I did find a user manual. Which is very strange, the cover of the user manual displays something like a dozen different CRT TV model numbers and this one is just one of many. It lays out several non-specific features for all of these TVs and names a few when there is a specific feature to talk about, but there is nowhere but that cover which ever mentions the model number TXN2668WHF.
Does anyone have a service manual for this model? Or know how to enter the service menu?
