good morning my friends, I have a tv, chassis, ph03-08105, kxtf2106 model. The problem is that the judge is unstable. of the resistance and disconnect the 5v regulator and the voltage stabilized at 60v by measuring with pin-to-pin micro mass I noticed that pin 56 measures short with chassis (the micro is om8370ps / n3 / a I want to know if I can replace it with the om8370ps / n3 / 2 greetings

Friend the R539 is 5K or 51k?

Electronic R539 is 5k and they have two resistors in series of 5k each.

I think it is not so, they must be 51 K and they are the ones in the source control circuit, I recommend that you place it again and remove the L453 and place a 60 watt bulb in parallel with the C528 and measure the voltage there and comment the results.

Correctly place the 51k resistors and perform the test that I indicated before changing the onechip

Hello Friend. the direct replacement of the ic. om 8370 -n3-a is tda 9377ps-n3-a and tda 9381ps -n3-a. that of the script means simple or diagonal is that my computer does not have that sign. I hope the luck data served you

what a good fact of the two boys friend then I was wrong with the resistances is that at first I found them open one is r539 and the other is r539 a and in replacement of the two still
put a 10k thank you electronically but I think the mike is bad because I was working with this board alone without the screen and those micros as it is damaged very easy I will put the corresponding resistors and do the test you say greetings

good morning friends I did the focus test it turns out that now the problem got worse because I had solved the mike before and I stayed two tracks together when I did the test with the focus I had no time to measure anything because it started to smoke at (r561) then I disconnected it and half-cut the (vd564) and the one that made it measure in short was the micro one chip now I have another micro but I want you to give me your help Again what value is the resistance (r561 ) regards
