Error 4 means an I2C4 communication error detected by the Viper BGA (Ball Grid Array). Basically it means you have a bad signal board . On a LCD the SSB controls everything it detected an error and shut itself down. Easiest thing to do is Order a replacement SSB. 310432842641 this is the 12NC number for the SSB or u can look it up online by model. Just good luck on finding a replacement cheap !! The removal of the cable was too see if the SSB was the error and it was.

it sounds as though there is a problem on the main board and yes,it will be expensive to repair.i would guess between 400 to 600 possibly more depending on how much damage is on the main board. i know this isnt what you want to hear but i have a friend that has a tv repair shop and i know he gets big money for repairs on big screens.

Take a look at the stitch length dial. If you turn that dial counter clockwise (to about 7 o'clock), it will set to stretch stitch. Then all of the stretch stitch features will work. When you want to go back to straight stitching, just move that dial back to what ever stitch length you wish.
