Issues with LG LCD TV's and LG in general?

Question

Great TV - when it worked.
I bought a 42" LG LCD TV on boxing day 2007, the TV comes with a 2 year parts and labour warranty. November 2008 the TV stopped working. I took it to the repair facility where I told them I did not have my purchase receipt, but had a copy of my mastercard statement which showed my purchase. They said that was sufficient proof and proceeded to repair my TV.
3 weeks later my TV failed again. I had it repaired again under warranty by the same facility, and still my mastercard statement was sufficient proof of purchase.
3 days later, the TV failed again. I contacted the repair facility and they said that it was LG policy that if the same failure occurs a third time, the TV will be replaced with a new one.
They sent a replacement request to LG, and it was denied because I did not have sufficient proof of purchase.
Does this seem hypocritical that is was OK to fix my TV under warranty with my mastercard statement as proof of purchase, but as soon as LG realized that they have to fork out some cash to follow through with their warranty policy that they decided my mastercard statement is no longer sufficient proof?
So I have now been in a 4 month long battle trying to get some resolution because I have a 1.3 year old TV that hasn't been used in the past 4 months that I basically have to throw in the garbage because the motherboard is the failure and costs about as much as the TV itself to fix.
(Some additional information: the manufacture date is on the back of the TV and says September 2007, so even without proof of purchase, the TV is still under warranty)
How far should I go with this?

Answer 1

First call the Better Business Bureau and file a complaint.Also if you remember where you bought TV ask for a copy of the sale.Call LG back and tell them you filed complaint and are calling local news and giving them all the info and give the world a chance to see how LG takes care of its customers,you may need to speak to a supervisor on the LG side.

Answer 2

Go to the store you purchased the TV they may well be able to get you a copy of the Original purchase receipt Make sure to bring the credit card info when you go ask. Also inform the store, they may have more clout with LG. See if they will handle the return for you.

Answer 3

That is why we lay our treasures up in Heaven -- however, if you are in the right, which it sounds like you are, I would tell them that you will file a complaint on them and then sue them --
