Samsung LN-T4066F Problems...

by TC009 / July 6, 2010 7:49 AM PDT

Hello all,

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!

Samsung LN-T4066F Problems...

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.

There is a fix

TC009 -

Hopefully you haven't thrown out your tv (since this was posted 3 months ago) or taken the advice of HDTech. The issue is the capacitor and Samsung has finally come around and admitted they know it is a problem with their tv's.

There is a one-time free fix for capacitors... If this is NOT the problem then you pay for the repairs, but otherwise, they will come to fix it within a week... I suggest you at least contact Samsung and check to see if your Serial Number qualifies. By the way... I have the exact same model and my TV does qualify.

Here's the number for support: 800-726-7864.

Samsung LN-T46 power on over and over solved

Is now 9/2012 and we have solved our LCD Samsung multiple times power up problem. A few months ago, our LN-T46 ......../XAA started to cycle through power up 2 times, then 3 times. Also recently started getting colored dots and then small colored streaks overlaying the program your were watching. Doing searches on the internet, I discovered there was a manufacturing problem with a capacitor supplier when these TV's were built prior to Dec. 2008 and certain models only. Here is the web site to see if you qualify for a free repair:

If you have that model with your specific TV serial number (proving manufacturing date), you will be covered for free replacement of capacitors and maybe power board even though your TV is out of the standard warranty. Call this number at Samsung and then ask for the "Capacitor Department". 800-726-7864

They are coming to fix ours this next week.
