B252A8B8-30F8-4DD7-A927-68698050A845.jpeg [1.03MB] Hello fellow I have a doubt when starting directly, the display is blank as seen in the image of the voltages in tcon and it seems to be correctly turned on 4 LEDs, the equipment responds correctly to the control and keypads which makes me think that the display or any component of the board attached to the request who has some information or a similar fault was presented to me, thanks a greeting

if the t with 2 flex to the screen disconnects one and tests, then you connect it and disconnect the other and test, comment if disconnecting any had an image.

Hi, franciscovallarta, I carried out this test and it does not present an always white image of my doubts that the display may be wrong

Hi, Telso, I only appreciate a beep when giving volume with connected antenna, the channels are not heard as I do not see, I don't know where the equipment is if it is in any menu

Of course, we are here to share knowledge, I will insist on it, that I find something wrong, you should find some capacitor or resistance that is out of value.

Hello chuchin67 thanks for your comment but I correct the display does not have the spilled liquid isolating certain tracks of the panel has managed to get to have some image which confirms that the display will almost certainly have damaged the cof due to some voltage increase in summary the display is to change but not for spills I hope it will be useful for future diagnoses

Good contribution partner but if so, why when certain tracks are isolated there is an image? With its bright colors and I do not doubt that what you say anyway is damaged either by liquid drying or by internal short thank you very much for the contributions a huge greeting

Hahaha man if it was mine it would be a minor concern since I quickly attach another display of one that I have in stock I will return it to its owner and finished work since the original samsung display is worth more than buying another tv thank you very much colleagues for your magnificent opinions and answers we are in contact greetings
