= 12.0en Dear colleagues, I have two Samsung TV UN32EH4000GXZE with double image, violet and at times loses color and one of them also has two or three horizontal lines on the bottom edge. The model of the screen is 32ap04s4lv 0.2 = 12.0pt = 12.0ptRealicé the procedure indicated by the colleague Felipe Lerma [/url] = 12.0pt: cut [url=http://yoreparo.com/usuario/2388980/Felipe%20Lerma] the STVP track and the defect was not removed. Then I cut the other two tracks to the right. When the TV turned on the image came out perfect but immediately gray vertical lines began to appear, which came out from the bottom of the image across the width of the screen, these lines became dark until leaving the screen almost completely dark gray. This happened to me with both TVs = 12.0pt-Please the colleague who suggested the procedure can tell me what happens. = 12.0pt-Does anyone know what the CKV1, CKV2, CKVB1, CKVB2, STVP, etc. signals are? What function do they perform, what circuit do they generate and why do some TCON have more signals than others? = 12.0pt-Other colleagues gave more suggestions: cut a track on another side, cut two other tracks further. I did not dare to try these procedures. Please can someone explain the reasoning for me to choose which tracks to cut on the different screens and in which case. What is the basis of this strange surgical procedure? = 12.0ptAn affectionate greeting.

cutting the tracks is a possible option to repair the screen, but if the damage on the screen is large, this procedure does not work. is given as an option for a manufacturing defect, in samsung panels, I leave a list of procedures according to the screen .... greetings.
