Re: Power Trouble with LG 47LN549e-UA with ezsign software



I was starting to think that as well. I just wanted to be sure before ordering new LED strips. though it is starting to look like that may be my best option. Any preferences on sites to order from other than shopjimmy and TVchop shop.(besides Ebay)...

Re: Power Trouble with LG 47LN549e-UA with ezsign software



Possible. I was also wondering if it is tied to the fact it has ezsign software. It turns the TVs into marquee signs for businesses. These were used at a restaurant for that.

Im working on 2 LG TV's model numbers 47ln549e-UA. They will turn on then flash the LG logo, then turn back off. The indicator light will flash 3 times. Ive replaced the power supply board in one to no avail. Voltage readings seem normal but i cant find the service manual for this model anywhere so im not sure if the voltage going to the backlights is correct. I also cant find an error code guide for LG tvs. I was thinking it may be bad LED strips but since its both tvs (they are from a restaurant,went bad at the same time) im wondering if its an issue with the ezsign software. Would like some...
