Haier 75" 4K tv with no backlight (everything else works) for $50... would you take the gamble?

Getting this out of the way, it's going to be a nightmare trying to figure out how to transport this thing however a coworker recently received a cheque for his tv via warranty for the backlights dying off on him. He said it started with the top corner and then not long after that they all went out (assuming they're wired in series?).

He offered the tv to me for $50.00

I thought to myself, well $50 is a gamble I wouldn't mind trying to work on and fix (and then resell for cheap but still make a profit) instead of losing the $50 at the casino...

Not sure how much a tv of this size by this brand (I know they're not that great) with a 4K panel goes for on the used market but what would you guys here do? It would be good practice to work on this as I've started getting back in to doing repairs on the side of work (and have made about $350 so far in about 2 weeks just working on game consoles). The way I see it is if I get the tv and replace the lights, that could be a massive profit to make... I'm cringeing at wondering how the hell I'm going to safely remove a 75" panel though...

Anything to do with the panel itself it’s hard to fix. I got some lines on a dell 8k monitor and I took it apart and I found out it’s the inside glass connection has the problem from too much heat. Not the side on the control pcb tab has problem.

In-laws took a projector tv home and then delivered it for free from yard sale and the light bulb inside broke. Cost like 50 bucks to replace the bulb. I didn’t bother buying the bulb. Tried to fix the old bulb still lit but the silver reflective stuff is flaking so light doesn’t shine right. Later for someone to take away on Craigslist. Pretty quick like half an hour after posting lol. You may end up spending a lot of time and money fixing this. Tv is so cheap now just get a new one with warranty. I fix a lot of things some are worth fixing like expensive lenses, audio equipments. If you get them for cheap. Still a risk. If you are single and have lots of time then by all means take things apart and try fixing and can learn.

I took apart many things tv, microwave, monitors, canon L lenses, 1 series cameras, and a whole car stripped down to frame. Fun times.

Decided not to take it after he sent me pics of the pack showing the model number and there was a gaping hole for the wall mount part that was broken right off. Too bad as it could have been a decent profit.

My guess was the back lights were wired in series and one died, killing all of them off until either a jumper wire was run or the strip replaced.

(assuming they're wired in series?). yup most likely... let's look at this way, replacements are going to be ~$75, hassle to fix a day or more if the lights didn't take down anything else, let's pretend a smooth repair (ha), it's clearly used and most prospective buyers would want a deep discount and some, let's say you pick up without using most of your favours, and the buyer takes it dust & all, I expect you would see sub $300 or that. Now let's go back and look at some of the variables, part doesn't fit, part is held up in China 3 months, power supply for the back-light is compromised One of the reasons it died) , the new part is not up to snuff, you crack something in transport, the panel is sitting 3 months in a room with floor hockey while you carefully handle online offers and get angry at low-ballers. If this sounds like too much business, pack it in and admire the fact that these panels com in dirt cheap atm and Costco's 5 year warranty looks great.

"Too bad as it could have been a decent profit." or likely a big black elephant.
