Question about LG Televison & Video
Had a short in house. Tv was off. Turned on and had red standby light blinking in lower right corner. Would blink several times and go solid red. Replaced the psu. Same blinking red light. Replaced main mother board and got 1 flash then turned blue, no picture and no sound. Replaced t-con, same results. Black screen not lit at all.
How many times this standby/power light blinks at one time switch ON? Count it carefully. These blinks are fault indication, and known as blinking codes. From the number of blinks occur at one time switch ON; you can get an idea about the faulty circuit stage inside the TV. This will make repair easy.
