The convergence IC have gone bad, bad solder connections to IC or probably both. The board as a whole can be purchased as complete (look to the web to find where to get) and is fairly easy to replace. Unless you have extensive experience with component level repair I would suggest you take the board to a TV shop to repair. This option maybe slightly less then replacing board. Check with your local TV repair shop to see which option is the best in your area.
Instead of typing model number of your TV (that located on right hand side and on the back of TV) you published here part number of your TV's remote control. LOL. Anyway... If it is LCD/plasma panel that you talking about - than power supply have bad electrolytic capacitors that have to be replaced. You can recognize 'em by bulged/swollen tops (instead of flat tops of good capacitors). This repair required soldering skills.
You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.
If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.
Pull the back off the TV and locate the convergence board. It's up and to the right in the circuit board area and has two large black Ic's mounted on it. Locate the red colored plug to the left front of that board marked +/- 20v and unplug that. Now plug the TV back in and attempt to power it up - - - if it powers on the picture will be really messed up (unwatchable) but that will tell us if it's a convergence failure. This is the most common problem for these units with those symtoms...
Repairing it will be a snap then... Just let me know...

chances are its the red CRT PCB or the red drive circuit. Go to the following link and leave an email with your model number and indicate your problem they can get the parts you need and supply the tech support so you can install them yourself which will most likely be cheaper than a service call to diagnose the problem. Heres the link. http://servicemanuals.vstore.ca/
It's most likely convergence -- the small board up and to the right inside the back of the TV, which has two large amp Ic's attached to it..
Unplug the +/- 20v line on the fron left corner of that board (red in color) and then try and power on the set... If the set comes on the board needs to be repaired and it's an easy unplug and two screws that mount it inside.
Well, fortunately the television that you purchased has an auto-convergence feature. What is happenning is that your color lamps are misaligned, did it get moved at all recently?
Anyway, in your menu you should see a "Convergence" menu, and inside that menu, a section called "Perfect Focus". Run Perfect Focus in this sequence: Green --> Red --> Blue
After that your picture should look great, if not try tinkering with the manual adjustments on the "Convergence" menu. Here are some URLs that you might find helpful: (just copy+paste into your browser)
