Being ripped off ( I think)

Most repairs will have some type of guarantee. I'd call the shop that did the work and explain (calmly) that the repair did not fix the problem.

They may have tried to repair the board unsuccessfully, rather than replace it -which probably would have been cost prohibitive.

May just be a bad solder job that was only discovered once the set heated up from continuous use.

Give the shop a chance to make things right. If you paid for the repair with a credit card, you can try to contest the charges if they don't fix it. Even if this doesn't work, it usually gets the shop's attention by the credit card holding or withdrawing the payment until the issue is resolved.

if you plan on marking the board, I'd recommend gently asking if the plan is to replace the board.

If the guy replaced the board once, he may not do it again. He might just re-solder or position it or something.

In 30+ years of working with printed circuit boards, I've never heard of one cracking (e.g. unless abused with great forces). They are very strong, usually made of fiberglass and securely fastened.

Sounds like you have a cable/connector issue, between the Main/TCON boards or TCON/Panel (e.g. wires making poor contact to connector, connector contacts dirty/oxidized or poor solder connection between connector/board.).

Wasn't under warranty? Damn that sucks - Depending on how old the TV was, i probably would suggest you kindly ask for your money back as they did not repair the TV and use that to purchase a newer TV, and make sure you buy an extended warranty; squaretrade offers 40% off coupons all the time, my $2100 HX850 got a 4 year warranty for $75 couple months ago.

TV prices are falling so fast that it doesn't make sense to buy extended warranty anymore. Most credit cards extend factory warranty for another year if card was used on the purchase. I'd say if TV breaks down after 2 years just toss it or sell for parts and move on.

Now that the shop has your cash, and you still have a broken set, getting the successful repair that you paid for seems to be the primary objective. Don't accuse the shop, or be overly aggressive with them, even if you are frustrated.

Be polite, but firm. Keep your language in the same ballpark that you would use with your mother or grandmother.

You should expect either an effective repair for the price paid, or, a refund of the price of the unsuccessful repair.

Most businesses are not in the business of ripping off their customers. Some are better at doing their jobs than others, but even the bad ones should get a chance to fix a screw up before you allow your blood pressure to raise.

Best of luck getting a satisfactory resolution.

I agree, and they're a pretty good money maker, which is why they push them. Yes, if your TV croaks one day out of warranty you might wish you'd gotten one. I'll play those odds though.

I certainly thought about it when I shelled out over 2,000 bucks for my 65" LG. But like you say, I paid with a credit card. Almost one trouble-free year now, and one to go. Chances are I'll have an 84" 4k set by then for my HT and the 65" TV will be relegated to the living room.
