Re: Help needed! LG 47LV5500-UA with no video or audio (Resolved!)

@nomoresonys Thanks!

It just felt like the right thing to do, to me (although I have to admit I used to write monthly woodworking articles in a semi-professional capacity, so maybe I'm the odd bird?) especially since quite a few people (you included) took the time to assist with my unknown issue. I'm really grateful this forum and its users are here, and willing to share such valuable knowledge! I consider it a great resource and I've already shared its usefulness as well as name/url with a number...

Re: Help needed! LG 47LV5500-UA with no video or audio

@tvtimmy @freakaftr8 @nomoresonys @R_J @mmartell Thanks everyone for your assistance and input. I finally was able too get back to the TV and got her going again. Voltages looked fine so pulled the green board, removed the heat sink from the main processor, and using my heat gun, used a focused but somewhat pulsing heat on the processor. Let it cool back down and back together she went. I tested it before the back was screwed back on, and then again afterwards, just to make sure. Who knows how long this will last, but I’ll...

Re: Help needed! LG 47LV5500-UA with no video or audio

Just before heading to bed, I decided to try the TV again, since I'd unplugged it on its last fail. Not too surprising that it again failed, but I noticed something that I'd overlooked earlier. When I plugged the TV into power, the red standby light came on, but only for a second or two, then went off. When I tried turning it on via the remote, the red standby came on, and then shifted to a white light. When turned back off via the remote, it shifted to the red standby for a moment, then no light at all. I'm curious if this...

Re: Help needed! LG 47LV5500-UA with no video or audio

Thanks again @TVtimmy ! I came in to work on it some more and had an idea that I should just plug it in and test it, since it's been plugged into power since 2012. Sure enough, the main LG screen came up and then showed which HDMI was chosen. I unplugged it and screwed the back on. Plugged it back in and, yep, back to the black screen like before. I only post this on the outside chance that this might be indicative of some other diagnosis. I'll be unscrewing all of the dang little screws again tomorrow. lol

Re: Help needed! LG 47LV5500-UA with no video or audio

Thanks @tvtimmy ! Is there any tricks to removing the heat sink? Just so a ham fisted guy like me doesn’t do irreparable damage while trying to fix. Also curious if There are any visual indications regarding success? Or is it just a matter of reinstalling the heat sink and testing the TV? Appreciate the assistance!

Cheers

Hello all,

As I wrote in the title, I own an LG 47LV5500-UA that we bought in 2012. My wife and I were watching some of the early 2018 Olympics and during the broadcast, it just went dark and emits no audio. We weren't having any weather at that point, so it just seems as though it reached its limit. When trying to turn it on, after it cut off, the red indicator light is initially on, but turns to a white light after I press the remote's ON button.

I have some electric experience via my old side business where I repaired old tube guitar amps, as well as modding some...

Re: New Members - please post your introductions here

Hi guys

I’m new to the forum. I’ve got some electronics background, but very limited TV exposure. I used to repair/modify (primarily) tube guitar amps, but haven’t had any on the bench for five or six years. I’m hoping to get some good insight regarding an LG 47LV5500 that went from awesome to mostly brick (power light is red, and turns white when pressing remote power-on, but no image/sound nor background LED) in the blink of an eye. I hope to repair and give to my kids or a needing friend....
