That is a panel related problem.
The main Panel or T-Con board most likely (T-Con boards are considered part of the "Panel" by most manufacturers)
A connection problem would probably show much slower changes in the picture.

Check out this tread maybe ? http://www.avsforum.com/t/1373343/problems-with-a-sony-kdl-46z4100-3-wide-vertical-bars-of-discoloration
or this one http://www.lcdparts.net/howto/symptom.aspx
could be binded tab panel connectors ?
if you put light pressure on the bonded panel tab connectors at panel or the board and it starts working better that *may be the answer ! You may have to remove front plastic bezel (usually do ) to inspect bonded panel tab connections the panel has it's own frame behind front plastic bezel. good luck!
TABs, or tape-automated bondings, are an integral part of any LCD monitor. These bondings connect the information they receive from the processor (T con board or other display control board ) and send it to the tiny transistors in the panel that create the electrical currents that ultimately affect which colors or if anything you see on screen. A TAB fault -- also called a TAB failure -- happens when these bondings are damaged or otherwise disconnected from the processor.
*usually* tab failure will affect part of screen if only one connector faults but not always .

*************** Cautions *************************
LCD CCFL backlight TV Can have ~700 -1000 + AC working voltage to operate CCFL (florescent tube backlight) take appropriate cautions
Plasma TV also has similarly high working voltages
LCD/LED does not have high voltages other than (like the others) mains voltage at Power supply board

Thank you VERY much for this detailed answer. I'll take my TV apart next week-end and take a closer look at things to see if any of these ideas you've proposed solve the problem. Thanks for your time and effort helping me out.
Took my TV apart and no visible issues with capacitors... I took out the tapes from their clips (there were two) and reinserted them, same issues.
Going to take my dismantled TV to a repair shop in the morning.
Repair shop said it wasn't repairable. Said it was most certainly the TABS going into the LCD panel. Possibility that the foam block method mentioned might work for a bit but it would not last.
I recycled my TV...
keep us updated to what you get.
I no longer play games or watch THAT much TV where super amazing quality matters to me anymore. So I'm looking to get a cheap 50" TV. I've identified these two models as potentially good $800 options:
Unfortunately there are no reviews online that I can find or threads devoted to these models in these forums, so I'm a bit wary. I might end up spending a bit more money or a model that has a good track record, I surmise that these two models are discount models slapped together to move old inventory (which in theory I don't mind... I just need a track record to make me comfortable with my purchase!).
Couldn't find one on the Panny maybe it's to new seems like the newer Panny LCD's have been getting good reviews maybe you can go see them I think both are good choices to look at ?
To tell you the truth if I was looking for a 50" led these two would be on my shortlist hands down! I would not hesitate on the Toshiba but wouldn't mind seeing Panny and the Toshiba together or even separately either .Are You near a store or no? maybe read the customer review at Amazon and Future Shop /Best Buy
Here is a review of the Toshiba http://reviews.lcdtvbuyingguide.com/toshiba-lcd-tv/toshiba-50l4300u.html
Scored this guy: http://shop.panasonic.com/shop/model/TC-L50E60 for a modest $900 CAD (best price I could find was $800 USD on Amazon.com and Vision Electronics wouldn't match an American site...)
Was looking really close at the Toshiba I posted above but I was drawn to the much thinner profile of this new panasonic. Silly me though, I only realized now that the TV is out of the box and being set up that it only has a digital out! I use some kick ass BOSE computer speakers for my home theatre and they need RCA out... FUDGE!!!!! What to do? Use this as an excuse for new speakers?
I've never bothered with the receiver... I've always wanted one but never really been able to justify the purchase as I can funnel all my video sources through my TV via HDMI and then out through the audio out on the TV. My Bose speakers have served me well, I purchased them for my PC many years ago then when I stopped using a desktop PC I pulled them into my living room and hooked them up to my TV. I've been really happy with the sound (though granted I'm not a massive audiophile) and their low profile. I have this setup: http://*******.com/kn78me6.
Looks like I can get a digital audio to RCA converter for about $30:http://*******.com/pzv7dt9. I'll do that for the time being. Once I move into my new house in the new year I'll investigate getting a more robust speaker system for my TV.
