I moved my TV recently, and the picture now extends off the left side of the screen, such that items on the left of the picture are off the screen. There must be an easy way to recenter the picture, right? Help?

when picture is getting smaller in size or goes away or moves towards one side then hit your TV lightly on left side or right side or on top & then observe ..........you will get normal picture or it comes & again it goes....if it is happening like that then following is the situation..........after 4 or 5 yrs in some TVs on main board at some soldering joints crack develops....then due to loose contact picture becomes small in size or disappears ...........when we hit that lightly then those loose contacts joins temporarly & again picture appears for some time............so solution is ......TV main board should be observed carefully & most of the joints should be re-soldered.......only a good service engineer can do that........even after hitting TV lightly if there is no response then main board has to be checked completely........in your case iam sure it is loose connection problem.........joints should be re - soldered ...100% it works again................this problem cannot be solved by user unless user has idea about components( resisitors, transisitors, diodes,...etc) , have soldering iron , multimeter & other tools....................so contact good TV service engineer
your picture tubes is going bad. i've had 5 yes 5 of these tv's replaced by samsung/bestbuy. i've kept buying the PSP (product Service plan) now my most recent tv is doing the same. samsung no longer makes the picture tube for this model. i've already called them. it was a nice tv. i've gotten about 6 months out of each model. I'm moving on the LCD, nice rca 32 inch HDtv model at walmart for less than 500.00.
I spoke with Samsung - they said this is a minor and easy to fix problem caused by a "blocked or collapsed channel" - whatever that is. They also recommended that if I have any warantee coverage (I do) that I not attempt this repair myself and that a technician be called in. That's my plan. I hope this helps.
Have you had any kind of magnets close to the tv set? I had a brand new sanyo do the same thing. I had pulled the speaker box out of my truck and stood it up next to the tv (not thinking about where I put it). Turned it on a few hours later only to see a messed up picture. I moved the speaker box to get behind the tv and the picture got better. Moved the speaker box back to the truck and after a couple of days the picture was back to normal. These were 4 large magnets on these speakers. Maybe I helped some!
Some of the problem could be a weak or damaged picture tube - especially if it encountered rough handling in the move. Other possibilities are bad capacitors in the power supply and deflection circuits which are common with this aged set. No adjustments come to mind that could permanently fix these symptoms.
Problem 1. Color patches at lower corners. These are caused by magnetic sources close to the TV. Do you have any Speakers close to the sides of the TV? Are they Magnetically sheilded? No? Move them away from the TV. Problem should then resolve itself in a couple of days.
Problem2. Screen Slumping. Most likely a problem with the Pin cushion correction ckts. Get a good technician to have look. cost should not be much. Under 100$ plus Technician fees.
