TROUBLE SHOOT LC-60E78UN TV


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Is the switch powered up ?


Faulty led of the switch generally glows when the hardware latched to it goes faulty such as fans and power supply. please check for LED in any of these. if you won.t find any LED in red in any of these then try to connect your switch through console port of the switch, if the out is coming as garbage value ie it is not asking for username and password the try to power off the switch ( your live services will go down running through that switch, so plan a MW for that) .

Video goes off led blinks 5 times then video returns, audio ok


  1. Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly. For more details, check this.

My Sony KDF-50WE655 does not turn on. Only the standby LED Flashes several times and then goes steady green, but the lamp light remains off.


Hello
You just count the number of blinks of the standby light before it goes out to green. In sony sets this blinking count ic critical for us to locate the faulty stage. You just count it after switch it Off by Power switch and Switch it On by the power switch at the front of the TV, for at least three or four times, and make sure abut the number of blinks, and report it to me. Ok
