Have TV Questions? Ask a TV Technician
HI, my name is ***** ***** sequence did you use to try and force power supply on?
Okay the 2x5 error code is failure of the 12 volts to the LCD panel (screen) this issue is very common in this TV. Most of the time it is failure of the panel. Are you comfortable taking the TV back off the TV to trouble shoot?
Okay we can try a force on if you like, can you tell me the sequence from top to bottom of the buttons on the side of the TV,
Okay, unplug the TV from the wall > press and hold the channel down and volume up buttons while plugging the unit back in, it may take 2 people if the outlet is not close, hold the button for at least 5 to 10 seconds to after you plug it in to see if the unit turns on?
you couldn't do any of that before either right?
Okay, we just forced the power supply to run but the back lights in the panel did not light, we would need do another test with the back off to determine if the LCD panel is the problem.
Alright we may go back and forth a bit as I am mostly on line on Sundays not so much during the week but I do check in every day.
