Swelling Picture After being on for approximately an hour, the picture starts to swell or expand. If we put a fan on it, it goes back to a normal picture, but we have to keep a fan on it.

Swelling of the leg may involve a noticeable distension of the shin or calf, ankles, feet or toes. Foot swelling may be a common occurrence which most of us will experience at some point in life after a long day of standing or sitting but may also be an indication of a more serious pathology as in certain cardiovascular disorders.
Recurrent or persistent swelling of the feet should be investigated by a medical practitioner especially if you have a history of cardiovascular disease or have noticed a change in color, sensation or mobility of the leg, foot or toe.
Blood rich in oxygen and nutrients flows through the arteries to the target area. Blood carrying deoxygenated blood returns to the heart via the veins where it is quickly routed to the lungs to be replenished with oxygen.
Blood flowing to the leg has to return to the heart through a group of veins with intermittent valves located throughout the course of the vein. This venous blood (blood in the veins that is returning to the heart) has to flow against gravity and since the pressure is usually lower at the feet, other muscles of the leg assist with 'pumping' this blood back to the heart. This muscle pump is most active when we are walking and least when we are standing stationary or sitting. Blood travels short distances up the vein and backflow of blood is prevented by a series of valves in these veins.
Working alongside the blood vessels are the lymphatic vessels which return lymphatic fluid (lymph) back up the body to empty into the blood system.
Swelling of the leg usually occurs as a result of an inadequate flow of blood or lymphatic fluid back up to the torso of the body. However other localized causes may further contribute to swollen feet, ankles or toes.

Any swelling on a cap is bad sometime you wont see swelling ontop sometimes its on the bottom, I suggest replacing those caps then try again make sure you discharge the caps as well.
Also make sure its the right caps too!

1000uf 6.3volts or something like that. Ebay a good source for caps and amazon.

this indicates that the wrong charger was used for the battery type
it is a result of too fast a charge or the wrong charge (metal hydrox batteries against nicad batteries )

Unplug sooooooon to prevent damage to coils!!! Remove plastic wall. Melt ice totally with hair dryer. See defrost heater at bottom of coils. If good it will read 50 to 200 ohms. If bad it will read infinite ohms. If my guessing is right, it will read bad and will need changing, along with the small clip-on thermostat that sits at or above the top of your coils. Parts will cost you $50 to $100 on the Net, and you'll spend 2 hours max.

Its likely to be the color wheel which when fails can do several things: A high pitched whine or what is often described as a fan like sound.

Since the set monitors the speed of the wheel if it slows down even a little image may look odd or dark.

you can at worst hear a grinding sound and it means segments in the wheel are shattered or missing

Good news is it is readily available and many average people can replace it---you tube even has video instructions for most of the Samsung models for this.

Only two models were made and Google the model number with Color wheel to locate the one your set uses.

1. check the fuse for the fan motor make sure they operate replace if necessary
2. make sure the fans operate if not replace
3. check lower hose for restrictions/ wear/ swelling soft spots this indicates that the thermostat is suffering blockage, check top hose also for the same. soft spots normally occure when fluid is wasted on the hoses and likely to appear nears a swelling area. Pep Boys quote a price of $275. 00dollars but they didnt say whether parts are included.
4. Manufacture installed the proper stat from the factory stick with it when you cahenge and are notsure whether it was a hi /lo temp you change the specs and cause additional unforeseen problems it supposed to open and close at precise temps anythinf different could cause overheating and computer read the wrong information which will cause the computer to go into a limp mode .

I have the same issue with mine. It is the rechargeable battery that is expanding. It looks a pretty unsafe to me, so I've unplugged it. The issue appears to have been reported here:

when you removed the back panel if you look on the right side you'll see a round coil next to the fan you have to clean that out at least once a year,if you get a shop vac you can vac off the coil and then set it to blow and blow the coil out to clean it,if your food is staying clod you don't have a problem,when the machine goes into defrost there's a heater in the freezer that melts the ice off of the coil,when it comes on the temp will get warmer for like a half hour or so until it comes out of defrost and starts to cool again.hope this helps

When it goes gray, means that the T-CON goes bad after warm up or it does not receive the 12vdc feeding it from the main board, or the main board is bad, try running the TV with the back open with small fan blowing in the back, otherwise you can get a can of cold spray for electronics troubleshooting fro Radio Shack or repia shop and try cooling the T-CON bord or the main logic board with it to see will the pictures come back on. Also check the power supply for bad DC filter caps.

Replace the starter for the armature is swelled up when hot and biding against the starters fields in there starters casing. Upon cooling off the swelling goes down and the starter is able to operate again. Remember when metal gets hot, it will expand and upon cooling it will shrink back to the normal size. After so long it will quit working from being so deformed from so much abuse
