If you read through my posts, you will see that I had challenges with the LC-50LE550u. I thought I tested on the 60le550 but it may have been the 60le650. Time to take my pronto back to sears!

The 550 is crap. Everyone is having problems with it. I would take the codes that I confirmed for Component/AV for the 50LE550, run in into IRScrutinizer, then generate all 255 and start blasting codes. This is what I would do if I had this problem and your TV. Fortunately, I haven't been stuck with these entry level (possibly) mid level Sharps that clearly used different production parts for their products.

The suggestion above may be more worthwhile than expecting someone to produce a code for you. How do you think people figure this stuff out? If I had more time or was stuck with that TV< I'd do it for you. :-)
