Good morning companions, I come to you this time to see if you can help me with the value of the resistors that go on the plate of the push buttons of channels, power, volume, menu and TV / AV, since it came with this shattered plate already that they were pujaban with anything to use the functions and you can not see the value of each one, or if any of you will have the diagram would be of great help, it is clear that this chassis has the MA61250 as a jungle, unlike another different chassis that brings this same model, attached image of the TV to which I mention:

Good afternoon: Does the TV turn on? I would leave the buttons overridden, I would go downtown and buy the remote control that goes to the TV and San is over ... What does the jungle matter? The diagramming of the buttons can be the same on the other chassis or the next version of the same TV model. It does not have the resistor code bars, so they are not burned, you can measure them to each one of them, now that some values are not commercial, it is something else ...

Is there any kind of serial on the board that can be interpreted as a chassis? let's see if there are diagrams ...

Friend Neg2013, I mention the jungle since there is another chassis of this tv that uses the jungle LA76950 ....... and obviously the diagramming of the keyboard platelet resistors is not the same, I already commented that all the platelet is shattered and resistors values are not distinguished because they are also broken, the TV does turn on and it works but they brought it to me to repair the keyboard ...

Ok, the resistances are absent so to speak. Otherwise you can measure them with the tester, diagrams, well identify the chassis in one of those there are diagrams, well with some luck there are diagrams.

The truth is that I have reviewed the chassis everywhere and I do not get any number that identifies it, so I uploaded a photo to at least have an idea those who have come to have one of these on their worktable

Already managed to find the values of each resistor to activate each function, connect a potentiometer in series with a button and I varied the R and all the functions appeared on the screen and taking note of each value in each of them, and the results They were: (4.3k CH +), (2.7k CH-), (1.2k V +), (820 ohm V-), (430 ohm Menu), (270 ohm TV / AV), (0.0 ohm Power) There you have them For any partner who may need them, thanks to all who wanted to help, they are greatly appreciated, greetings ...
