Goodnight; Apparently there are no diagrams of that chassis that says, but I'm still looking to see what can be found on the WEB.

good night neg 2013 if I was watching but I can not find maybe someone who has the same TV and so to see what values are those resistances

Can't JYM-471 use it to compare a little at least?

what happens is that they are 5-color resistors but maybe you can compare

Compare the screenshot, see how much the sources look alike, do you have dramas at the source, no? ...

if it strikes it, change the str but it goes out 150v voltages and goes down but where it should come out 11v that feeds the micro nothing comes out of zero voltage and that voltage is connected to those resistors and they are very suspicious that resistances does not regulate

If it is similar because these resistors 804 measures me 135k and 803 82k are very bad it must be that because it does not regulate tomorrow I change those r and I thank you

The source is from the screenshot, it seems, is it similar to its source? Did you change the KIA431 or TL431? You may have a short circuit in the stage that powers those 11 Volts that says ...

Of course, I look and it shows green, green, black, it follows another color, it seems to be brown or orange, but by the way it is serious orange 55k, they are tied up thanks friend

Resistance 831 I think it is also a prison but that is marked 2k and a little would be fine but r804 marks 134k and the r803 marks 82k that would be altered but I think this does not work if it is not a prison that they think

You have to remove one of the legs at least to be able to measure each of the resistors. With respect to the values it gives, simply if we rely on the diagram, and there is no more turning to give, the resistances are out of value. Now that this kind of resistance is commercial it is something else.
