Samsung 55" cracked screen

The same thing happened to a relative of mine. They still have the tv but it only occurred when they dropped it. The screens layers inside must have cracked. It could have also happened from pressure being put against the screen in the area of the colors. They asked the shop they bought it in & was told it can't be fixed and they would need a new one. Hope this helps.

T-con or display or main

You no longer have a TV but a parts unit. In most cases, It will cost more to replace the screen than buying a new TV set. Although it is cracked, it still has some value, don't toss it in the dump. Throw that puppy on Craigslist or Ebay(if you have the shipping box) someone will be interested and buy it. Just be realistic with your asking price. Don't be like some lady I encountered who wanted $350 for her Dynex 42" LCD with a cracked screen !!!

I have a new one and it was warped when I received it.

You must replace the conversion IC's. Part number: STK-392-xxx
Make sure you also change any open resitors!!!.

There are no settings that could produce that result.

On most LCD TVs there is a LCD controller board that controls the vertical/horizontal display output. It sounds like your LCD controller has failed.

When you say 'appears to be cracked'...you mean it is actually physically cracked? That is a different issue altogether. I would say 99.9% of screen fractures are due to rough handling or a stray impact with a Wii controller, but rarely screens can fracture due to manufacturing defect or a sudden change in temperature or altitude.

yes ..it is cracked..the screen must be replaced...and you don't have to drop the phones for this to happen....leaving it in the sunlight and exposed to cold and hot temperatures causes the screen to contract and expand...which eventually cracks them from the stresses...so...not your fault...no worries..but yes for sure...the screen must be replaced or get a new phone.....

Replace both STKS ICs Ck low ohm resistors 2.7ohms most of the time there will be 2 of them bad.

This is a convergence problem. It happens to all big screen rear projectors. The convergence output ic's need to be replaced. I would let a repair man do this.
