Bad news. The yellow spot is probably the result of a burned phospor spot in your blue CRT (blue projection tube). (Yellow is the opposite or absence of blue.) Probably sometime in the past, your TV turned off (or suffered a malfunction) which allowed the picture tube to remain on for just a second AFTER the sweep circuits stopped. There is supposed to be some safeguard circuitry to prevent that from happening, but for some reason, it failed to do it's job, with the result that it burned a "hole" in the phoshor of the blue CRT. You can check this yourself by removing either the front or back (depending on the model) and looking directly into the blue CRT lens while it is on. (Keep your hands away from the high-voltage circuitry beneath the tubes!) Unfotunately, the only way to fix this problem is to replace the blue CRT. And more unfortunately, it's almost impossible to get replacement projection CRT's anymore. Sorry!
