tv philips model 39PFG4109 / 77 Dark screen with sound

This post was translated, if you want to see the original version click here
I found that the problem was in the LED strip, now the new problem is that this TV burns the LEDs on the screen, I had read in a post that the source could be modified so that it delivers less current, but I can't find that source and less those resistances to be cut. I need help.


2 Proposed Solutions

SOLUTION ACCEPTED
Apparently it's an old post of mine haha. How can you not find the source ?, It is the same power source where the 220v enter. Look closely, the resistance, not the cuts, desoldalas.

    Yes, I found your video too: https://youtu.be/9jEuuRpG4mM
    but it didn't help me since my model is 32 "and the source does not have the same resistance, the model is: tv philips 32PHG4109 / 77F
    I already changed the LEDs burned by new strips, the problem is that since I did not find the resistance to lower the voltage drop in the LEDs, they would burn in a few months and I would have to buy new LEDs

    The video is not mine, but in the post title it says 39 "and PFG series. In the source you have exactly the same driver, nothing else changes the nomenclature, the return MOSFET is the Q8101 and the source gnd resistors are the R8123, R8124, R8125, R8126, take out the first and last and measure.

    Thanks for the help, now I take them out, and I add one like in the video?

    No, do not add anything, if you want to take half past one, if it is still high, you take out another.

    I took out the two resistors, measured and gave me: 18.3v
    Thanks for everything crack, you helped me.
