My lg 50uh5530 wont power up. Red light flashes three times.
My lg 50uh5530 wont come on. No sound, no picture, and the red light blinks three times. Read many Q and A's to discover that this problem can be multiple components from the power supply board to the main board and even the led strips in some cases. I've tried unplugging the unit for 24hrs twice with no luck. I have removed the back cover to visually inspect for damaged capacitors or loose connections and found nothing. There is a faint ticking sound coming from the bottom corner of the power supply board near the capacitors. I also checked the 12 power pins with my meter and I do have a 3.5v standby reading but instead of getting 13.2v for the middle pins I get 6.5 to 7.0v. Looking for further advice to make sure I dont waste money. I'm prepared to replace the caps, the entire power supply board, main board, or any other component to fix the issue. Just dont want to buy an exspensive part like others have done when it may be something simple
Ist dies eine gute Frage?
