As long as the center speaker has been removed, the degaussing circuits should have recovered normal operation of the set. Also, I find it hard to believe that a center speaker would harm a projection set given the location of the CRTs. Can you please verify the model number of the set as well as provide more details about what you mean by "wrecked"?
Thanks,
Dan

THE PICTURE IS NOT CLEAR A SHADOW BEHIND OBJECT, THE SCREEN IS OVAL


You most likely have a large magnetic source near the screen like a surround sound sub woofer or other speakers. also go into the tv's settings and have it auto adjust the convergence. should help

My surround sound speakers where too close to my tv and now my colours are messed up what do i do to fix the problem?


Seems the magnetic field from the speakers has caused the color purity in the televisions screen to become discolored, You might try unplugng the set and moving the speaker futher away from the television, Wait at least 20min before cutting it back on, There is a degaussing coil surrounding your picture whis supposed degauss the set everytime you cut it on. Much like you seen on older computer monitors when you press the degauss botton the screen would suddenly go to a rainbow of colors and then return to normal. Depending on how long the speaker has been there you might have to call your servicer and have them come out and manually degause the set for you.

Green shadows surrounding bright whites


finally a consumer that gives us plenty of info :)
sounds like an overdriven green tube, the only thing you can try is to find the G2/Focus block assembly, either behind front speaker grill or remove back of set and look for a black box approximately 5"X5" , this box will have 6 philips type adjustment screws(plastic) 3 are for focus, do NOT adjust these,
the other 3 are marked "screen" the center screen adjustment screw is for green, turn it VERY slowly counterclockwise while the set is running and pray that your problem dis-appears, be advised that this is a HIGH VOLTAGE device so one hand in your back pocket the other hand turns the screwdriver, if the problem does not go away you have a poor green tube, good luck, sorry I can`t give you the exact location of the G2/Focus block, manufacturers move them to different places every year.

Side shadows on picture


it sounds as if there are speakers to close to the tv or the built in speakers are not magnetically sheilded properly (maufacturer defect) if u have or have ever had speakers on the left and right side of your tv then the magnets in them will discolor and distort the screen. sometimes even long after the speakers have been moved away from the tv it will still look that way. you may try going to the library( or online )and looking in tv repair books on how to build a homade degauser unless your tv has that feature built into it in the menu somewhere like some computer monitors do. I had placed the front speaker of a 5.1 surround sound system on top my tv and it cuased that same problem, but i found out that by placing a small round magnet with a hole in the center on top of the tv (after removing the speaker for good) right where the discoloration was.. had to flip it one side or the other to get proper effect...it immediatly took away most of the discoloration and over time it disappeared. I hope this helps. Please email me at agclay777@comcast.net as to your conclusion in case it will help others. thanks, Adam

Can't converge the whole screen at once


A surround sound receiver wouldn't cause issues itself but the possibility that speakers could cause issues is there. Speakers usually are an issue with direct view CRT televicions more than CRT projections. Don't move any physical adjustments on the CRT's unless you understand what each magnet is accomplishing on it. It is a electrical alignment and most likely one that has to be done in the technicians convergence alignment settings not the consumers.
