Samsung 46" LCD vertical colored lines

[Woodless]

Hello all, I have searched the forum for my problem and while I have found similar problems, I have not found my exact issue.

I have a 46" samsung LCD that has decided it needs irritating vertical lines in multi color and one that is black (which worries me). I have tried re-setting the ribbon between the mother board and the screen which did nothing. Attached is a pic that I hope helps to illustrate my problem.

Please let me know what you guys suggest as a repair while keeping in mind that while I am mechanically inclined, I know very little about TV's

Thanks all

Dan

You probably need to replace the LCD screen. But might as well open it up and post clear pictures of the insides.

Re: Samsung 46" LCD vertical colored lines

What would you like to see inside?

The power board and the main board at least. Just so by the time the bigger experts come around they'll have something to go off of.

Gotcha, I'll do that now...

t-con board would be good for a photo too

Here are the insides, hope the T-Con board is a part of these pics.

The T-con board is that board between the speakers.

How old is the TV? It is most likely a panel failure due to manufacturing defect. Complaining to Samsung is really your only option.

TV was bought in 2010 and from what I have researched the 08, 09 42" and 46" samsungs were known for this.

Under two years is ridiculous.

1-800-SAMSUNG (1-800-726-7864)
Mon - Fri: 8am - Midnight (EST)
Sat - Sun: 9am - 11pm (EST)

Demand they replace or repair it as you think it is ridiculous for a TV to last "xx" months and you spend $xxx on it and you have lost confidence in the Samsung brand. (Try and go for a store credit or direct refund instead of a replacement -- the replacement will come with 90 day warranty typically, but a store-bought TV would have 12 months minimum.)

It has worked in the past before & it's the only way Samsung will learn they need to stop producing poor quality products.

Thank you very much sir, I will take that advice and report back with my results.

Re: Samsung 46" LCD vertical colored lines

Good luck. The secret is perseverance.

Oh, and if you do get a store credit, avoid Samsung and get a Sony LCD, Panasonic (LCD or plasma), JVC, Toshiba, or Sharp LCD TV. The last three you need to be careful that you are buying a "genuine" JVC/Toshiba/Sharp as they also sell their name out but this can usually be verified by comparing the system menus and the picture quality, and asking around here if you need advice. Panasonic is my favourite as I consider Sony somewhat evil with their latest business practices, and Panasonic make all of their own stuff including LCD and plasma panels.

Sony evil? What have they done now? I am highly interested...

In one case, they sued the guy who figured out how to put Linux back on the PS3. There should be nothing inherently wrong with hacking your own hardware, but Sony disagrees.

Looks like I will be getting a "free of charge service". Told them that I own nothing but Samsung for my electronics (I actually own Apple hehehe) and for this TV to only last 29 months is ridiculous, make it right.

Fantastic -- how many operators did it take?

More than likely, technician will come, try swapping t-con, find out it doesn't fix the issue, then authorise you for a new TV. I doubt they'd consider it economical to swap the LCD panel itself.

Re: Samsung 46" LCD vertical colored lines

I got to the last operator and she backed out of the whole deal! So I told her I would take my business to another brand and then told her that Apple never treats me like this... lol

So, a Sony BRAVIA KDL46EX640, how good is that?

Re: Samsung 46" LCD vertical colored lines

So, what, are they repairing it or not?

Re, the Sony: It's a decent TV. It uses a Samsung display panel, but they're generally pretty reliable (it's quite rare to see LCD failures; everything else on a Samsung dies first.) Obviously, your TV is an exception...

You won't notice the difference between edge LED LCD and CCFL LCD (i.e. "non" LED.) You will likely turn off the Motionflow 240Hz feature, as it makes everything look fake... I did the same with a 100Hz TV I kept. Reliability of edge LED seems poor as they're like christmas lights. One LED dies (there are hundreds) and the whole show goes out. The Smart TV functionality is neat -- but a home theatre PC is more powerful and generally costs less to implement.

May I suggest a decent Panasonic plasma, such as the TC-P46GT30? It'll have much better motion and contrast ratio than any LED LCD. And, it'll cost you less in most cases.
