At least backlight repair on an LG LCD is easier than doing front lighting on the Cadillac DTS. LGs seem to have a reputation, whether rightful or not, for great image quality (in their better-calibrated ISF modes or whatever they call it) and subpar backlights. And as an added bonus, the panel isn't glued in. Folks on the forums just recommend running the backlight at the dimmest tolerable setting to preserve them. For models made in the last ~10 years though, even 70% is plenty for a bright room.
@Browningate you are absolutely correct! Compared to doing the lights on my DTS, taking apart my TV was easy, lol! As it ended up, it was a ribbon connected to the main board that needed attention. I did adjust my settings. Since I made the video, the TV has performed flawlessly. But, in case I ever have a an issue, I kept the new light strips. I now have the experience to pull the TV apart and repair it if necessary. However, if it ends up unrepaired, I will likely shop a different brand to replace it. 👍👍
@@lilredcrvtt Good deal. My grandfather's LG actually fell victim to a burned capacitor on the power supply board. I was ready to tear into the thing and do backlights, but luckily had the presence of mind to try to fire it up first with the back cover off. When I saw smoke (and even a little bit of fire) pouring off of that capacitor, I figured that I had a gopher.
@Browningate that was good diagnostic work! I wasn't as thorough initially. The picture went black, and from my research I assumed it was an LED backlight issue. That seems to be the most common failure point on those TVs. But after testing each LED strip it was apparent that was not the issue. Somehow, through possible heat cycles, one of the ribbon cords attached to the main board had become an issue. This is not a typical failure point, but it was the culprit in my case. Next time, if my TV fails, I'll be checking the capacitors too.
@@lilredcrvtt That's fair. I kind of figured backlights going into it as well. That seems to be where they like to cut corners on LCDs anymore, and the failure mode is almost always the same, regardless of brand, so it's a reasonable assumption to make.
