All voltages, measured by you, looks like OK. Voltages, measured at the good-known M201EW02 LCD-panel below:
LVDS - AUO-030
VGG1 27,0
VGH1 23,1
YVCC1 3,29
YVGG1 23,2
VCOMAR1 5,3
VCCM4 5,3
AVDD1 12,6
XVCC1 3,2
V331 3,3
5V1 4,9
VCORE1 1,7
GAVCC1 3,2
EVCC1 3,2
This defect looks like bad contact between printed wires on the T-CON PCB and ITO wires on the LC-unit aftereffect. |

ментионез, что экран не имеет на стороне водителя (он находится в бутылке), я изменил экран, и это хорошо, уверен, это дефект экрана
zeinerf,Thanks for the reply, but what it means ITO?...btw i pressed by the flexband,but no effect |

cicalov, Write English, please. Russian, generated by automatic translation, is mis-understandable.
ITO - Indium-Titan-Oxide - transparent wires on glass. A lot of voltages give from the T-CON PCB to the "glass" through drivers in TCP-cases, looks like small "flags" at upper side of the "glass". Drivers in TCP cases mount to the T-CON PCB and to the "glass" (LC-unit) using a gluing though ACF (Anisotropic-Conductive-Film). Bad contact in ACF is one of frequent LCD-panels defect. |

sorry, i didn't know that google translate so bad
can i measure by the glass? eventualy to solder a wire by the glass? (maybe the same pocedure like in case of defaughing auto) |

or I could ACF "resoldering" with this...see pictures...work? |

did someone to "resoldering" wire by glass?...........кому-то удалось придерживаться провод в бутылке?.. |

Uneconomical to carry out such work. |

for this screen maybe ... but for LED TV 32 "-42" certainly worth trying .. right? |

Step-by-step pictures of the source driver remounting: http://archive.espec.ws/section101/file28889.html (use copy-paste for moving the URL to the a new window, direct click doesn't work). Five years ago, when 19" IPS NEC costed approx 800 USD, it was economically effective for high grade monitors. |

VIKTOR_K, zeinerf thanks a lot for the answers, but I thought the easiest solution, such as The CircuitWorks CW2900 is a micro-tip pen for drawing conductive traces on flexible and ITO (indium tin oxide) surfaces.
CircuitWorks CW2900 Features:•Quickly creates flexible conductive silver traces on Mylar® and flex circuitry
•Micro-tip for precise applications
•Dries in minutes at room temperature
•Highly adherent polymer system
anyone tried? |

How will draw the transition from glass to film? |

with a simple line, still do not know, it's only the stage of idea, but the manufacturer saids, it seems a solution:"The Flex Conductive Pen traces also have excellent adherence to Indium Tin Oxide (ITO) substrates. The silver traces dry in minutes and have excellent mechanical properties"
i want to know if someone did try that solution? |
