Late 2013 27" iMac LCD/Video Failure. Horizontal/Vertical lines

Hi. It's me again. The answer is yes I successfully fixed the iMac screen with a used replacement LG screen (direct replacement) from eBay. The cost was $430 shipped. It worked for two years until a few weeks ago. There is a vertical pink line going down the screen. The shelf life, again, was 24 months. So it seems Apple's supplier LG supplied massively defective screens and has yet to do anything about it. If there's ever a class-action or any kind of recall, I hope I get reimbursed. Now I have to make a decision... I wonder how long this second screen lasts? The computer is great otherwise. But I am thinking it's best in the future to build my own PC.

Update 9/10/15:

I took my iMac into the Apple store at Fashion Island in Newport Beach, CA just now and I wanted to update this thread. The technician verified that the LCD was indeed bad.

I explained to the technician and the store manager that my iMac was exactly 24 months old and while I understand it is not under the 1-year warranty any more, that Apple should good-will the replacement of my LCD screen given that the expectation of high-end product such as the iMac should not fail within two years of purchase.

While I understand Apple has no legal requirement to replace my LCD screen, I am disappointed that Apple, even despite my request, would not even cover any portion of the repair. Given the actual cost to Apple for this mass-producted part is likely well under 1/4th the retail cost, you would think it would be beneficial to Apple to at least assist a loyal customer with the costs of repairs relative to the negative attention and word-of-mouth. The latter is far more damaging if even one person is swayed against purchasing a new iMac. I, for one, certainly would not purchase one again.

It appears in an attempt of profits, market-share, and profit margin, Apple quality is going down as they increasingly source cheaper and poorer quality parts from various suppliers.

I'll continue to use my current Apple products but in the future, I will seriously reconsider before purchasing another.

Attached is my iMac plugged into the display confirming my LCD is bad. The logo/graphic you see is actually a reflection of the wall at the iMac store. See the lines on the screen? Even the technician agreed it shouldn't have went out that fast. He was nice and asked the store manager to consider covering the repair. Manager was nice but denied it.

I'm going to tear into the screen tonight and see if I can fix it myself. Apparently some have had issues with loose cabling causing intermittent connections.
