I have a 32" Samsung Dynaflat HDTV. The picture seemed to drop about 4" so now there is a big black area at the top of the TV. This is the second time it happened. 3 years ago we got it repaired but unless I can do it myself it isn't worth fixing again.
To explain the problem perhaps you can envision the really old TVs. At times the picture would fall and there was a little knob called "vertical hold" that would allow you to move the picture back up. It's the same here except obviously there is no vertical hold button. I have no idea why the picture dropped but as I said the last repair was $400 which isn't even worth the price of the TV anymore.

Re: Picture has dropped
Hi and welcome to FixYa,
Almost always, your described fault of the TV is the pump capacitor in the vertical section. These capacitors tend to leak due to the heat build-up in that area. Other than that, no other component (to my knowledge) could exhibit the same symptoms. Price wise, component cost should just be a few dollars something making the repair if done by yourself (DIY) worth the effort. This is a relatively easy/quick repair, what would be more challenging is identifying which of the hundreds of capacitor is the one faulty and getting acces underneath the board to perform soldering.
To help you determine which, initially identify which is the vertical section. The vertical IC is often a single in line package with 7 or more pins. This IC would be attached to an aluminum heatsink. It would be very close to a 4 big wires terminal/connector that goes to the yoke. Very very close to the vertical IC would be several capacitors, about 5, certainly not more than 10. Among these capacitors, 1 would be relatively bigger with a value in the neighborhood of 100uF/50V. This is the pump capacitor. Replace it with a similar value readily available from most electronics supply store including Radio Shack. You would need a soldering iron to effect the repairs.

It seems that you haven't setup the 16:9 aspect ratio. Refer to page 34 in your manual and look for 16:9 enhanced. Here is some nore ubfo on your problem. https://us.en.kb.sony.com/app/answers/detail/a_id/40227/c/65,66/p/61659,61660,61754,61803/
The circuit board inside is cracked and has broken circuit traces. This is common if a set is dropped. The usual area that gets damaged is around a part called the horizontal output (or "flyback") transformer. It's the part with a red wire leading up to a rubber cap connected to the top of the picture tube. The flyback is fairly heavy and usually there's not much support for the circuit board in that area. When the set gets dropped, the weight of the flyback can break the circuit board. This can sometimes be repaired depending on the extent of the damage. Often the breaks are very obvious and sometimes not. Some of the circuit traces are very thin and close together which makes finding and repairing the damage difficult. In some cases other parts and areas can be damaged as well. This kind of repair requires considerable troubleshooting and soldering skills, so you might want to let a professional shop give you an estimate for the repair.
If the cable was an SVideo, it's possible you might have a broken pin. Losing one of the 4 pins would still give you a picture but it would be in Black and White. Check both ends of the cable and if one is missing, get another SVideo cable.
The ticking indicates a feed back on the power supply - most likely the shutdown circuit itself because something up-circuit is shorted. MY first guess would be the HOT (Horizontal Output Transistor) - Second guess the FBT or Flyback Transformer...
I might have the service manual for that, just email me personally and make it clear what you're after. I get nearly 3000 emails a day and I be real lucky to remember what this is all about when I get the mail...

Greeeting from Belize you are having a problem either with cold solder or a problem in the power supply those lines are hum bars due to a defected filter cap.resolder your power supply if that does not solve the problem then you replace the power supply you can get a power supply kit from www.dalbani.com in florida.good luck.also make check in the vertical section if you cannot do it your self take it to a qualified tech to resolve your problem this should cost you about $75.00. to get it fix.
