Normal turns on, when you put any picture power supply (HDMI, AV or Antenna) it disappears the picture erasing backlight, turns off or freezes the picture as a defective screen.Capacitors C201, C202 and C203 at power supply, 1000UF X10V, in my case they were puffed out. Crazy defect seemed to be a platePedro Igor - Eletrônica Portugal

Don't turn onCause was the two TPS54240 shortly, I removed the 2 diodes were good, cause of the burning of this 2 TPS54240 was the IC that feeds USB port, was short, before replace TPS54240, I replaced IC2501 and IC2502 Code AY6397 = BD2242G I switched both and two TPs, soundSolved defectAndrei

It turns on, but does not turn on the backlight, a power supply for the LEDs is 38V in stand-by and by squeezing Power rises to 44 volts, not enough to light the LEDs, in my case even blinking the LEDs.Near the output connector for the LEDs has the SMD diode position on the DB1 plate, code on the body of the HBR3100 diode in the short circuit, I used the SK320U insteadAfter exreplace the short diode, the power supply went to 58 volts, which exceeds 54 volts, the 03 6 LED rules in series are 18 3 -volt LEDs. Then I removed R815 from 2R2 and on the side of 2R4 and the power supply dropped to 53.9 volts.MIGUELTV
