Hello can anyone help iv got a LG 50UM7600PLB TV AND ITS JUST DIED IV CHECKED THE VOLTAGE FROM THE MAIN POWER BOARD TO THE PIC BOARD AND IM ONLY GETTING 7.9vdc And should be getting 13.2vdc any ideas on which cap or diode is down pls any help would be great 👍 😊iv checked the power coming from the 12 pin lead from main board to the pic board

Update (08/31/2022) Hi pal can I just pick your brain about something when tv plugged in I’m getting 0vdc on led + & - but when I use the body as a earth then just use the + I’m getting 266vdc is that normal ?
@gman2000 there are no schematics readily available for this TV. Let us know what your boards are labelled as (I assume its a EAY65228801) and let us know if you have any power blinks from the power LED when you try to turn it on.. Post some really good pictures of all boards and let us know exactly where you measured the voltages. It sounds like you may have measure the stby voltage which is low. Check the power board for any odd looking component (blackened, missing etc.). Check both sides of the boards. These boards have failures on the diodes and the MOSFET’s. So pay good attention to the diodes around the power transformers. @gman2000 your power supply is supplying the correct voltage. Your set is in Stby mode at which point it is showing 7.8V, Only when the set is on do you get the 13.2V. Check your main board and check all the voltages on P201
