The TV doesn't turn on, it just turns on the STB LED and blinks a few times and then goes out. | Vs_det is a protection that disarms the 205v line of the vs, in my case the defect was the defective protection, even arming the power supply via ps on and vs on without the need for the main board the power supply disarms on the micro mcv14a which is responsible for the protections and power supply. | To resolve the doubt as to whether the defect is in the protection, turn off the jp869 jumper and the power supply will start working again without tripping. This jumper should have a voltage of around 2.6v, more or less, in my case it was above 3v wsound it went into protection. , this jumper is connected to the resistors rs866 , rs855 , da854 , the same good ones without replaces , the problem is the glue on the parts , remove the glue and replace the components , but I did it on all the components around these 3 that I mentioned too , just to ensure, note: do not leave the jumper disconnected, be a responsible technician, do not do this test with the board connected to the other boards, only perform this test with the power supply outside the TV, the jumper has no problem turning it off, it will not damage the board, but first measure to check that tsound are no shorts or other problems on the board! After checking if the voltage returned to normal on the jumper, something like 2.6v, then turn it on again. I hope to help with this tip but remember, only do it if you have experience, it's not a tip for amateurs, help the site post your tip, help those who help you!!! | Play Back |

It wouldn't turn on and then turning off after 5 seconds | Capacitor 222 on the tube plate | 2455 (cap47/25volt) was also replaced, the device started working again, but as a precaution I replaced the 7461, 7463 (bc337, bc327). After it kept turning off, the solution was to replace capacitor 222 on the tube plate | NilPassos |
