If the issue is a surge, it could be either the power supply or one of the boards that was affected. Unfortunately, the unit is out of warranty, and thus, any inspection or repair would be an out of pocket expense. With the symptom of none of the buttons working, that sounds like a board issue, but again, it would take an inspection to make an accurate determination of the damage.
That said, if you believe it to be the fault of a surge, often times surge protectors have a guarantee of protecting the equipment to a specific dollar amount, so that also might be worth looking into. You can check the model number and call the company to make a claim. I've never personally done it, but it may be worth looking into.
I know I am new to this forum, but I am having issues and need a little help if any one is willing. About 2 1/2 years ago I bought my first LCD flat screen, a Samsung LN-T4066F. I spent a lot of time researching the TVs, and found this to be one of the best on the market at the time. When I bought this TV, my intentions were that this TV would last quite a few years (This was one reason I was able to justify the purchase and the price). Unfortunately, a few days ago my worst nightmare happened - the TV appears to be broken. We had a thunderstorm a couple of weeks ago, and it seems that storm has something to do with it all. On a side note, I do have a Monster Cable surge protector which I thought was supposed to protect against this sort of thing. Please let me know how accurate I am with that. Moving on, here is what has been happening:
At first, the TV would just take a bit longer to power on. There were no performance issues once on. About a week later, it started to really take its time turning on, and sometimes it would seem to power on (but no image/sound) and then power off and then on again until it really did turn on. It kind of reminded me of trying to start a car that just doesn't want to quite turn over. This lasted another week or so. And then, just the other day, once the TV turned on, there were a bunch of vertical colored lines covering my screen with no picture or sound. Also, the power-up sound the TV makes sounds crackled/fuzzy. Once on, no buttons on the TV or remote work except the ON/OFF switch. This is where I am at today.
Can anyone suggest what to do next? From what I have read so far, it seems my TV is broken past the point of repair. It may be better if I just bought a new one. Like I said before, my intent when I bought this TV was to make it last a very long time. I feel that 2 1/2 years is not close to a long life of a TV, even in this fast-paced technological world we live in!
Thank you so much in advance. I really appreciate all the great advice I have already received from this website/forums!
