Re: sd tv inbalance screen.
There is a code to get into service mode, but you should read over the
service manual before you attempt to enter the service mode and change
any settings. You can really mess up your set very easily. You can get
the service manual at the link provided below, but you will need to
register with the site to get it.

The problem of your tv is the vertical deflection. Try to tap the side of your tv and observe if it will go to normal size if react the problem is the vertical IC there is a loosed or cold solder in the pin. If you are familiar with the electronic parts you can fix this by resoldering the loosed or cold solder to the vertical section of your tv. But if you tap the side and does not react you should replace the vertical IC, or you can contact a service technician to do it for you good day and best regards. Note before doing some trouble shooting you should unplug the unit.
this my good sir, (or mam), is a convergence issue. very common rca failure. there is a convergence power module that has a 130volt regulator that goes bad. this can be fixed in-home by experienced technician for less tan 300.00 including parts, labor .& service call. the chip is an stk730-150. mch
I came across it by sheer fluke I held the Number1 key and the very last key on my remote and held them together for about 10 seconds, this deactivated the lock that was on the screen. I asked a few technicians but, u know people just don't want to help anymore. So i hope that my solution helps someone with the same problem. Other CTC televisions can be fixed by the same method.
I think, TV screen has white-balance failure thats why TV light blinks 5 times.
While living in Pakistan, I can't fix your TV there. In my point of view, it doesn't cost much and you should contact nearest Sony repair shop.
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.
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.
