Panasonic pt 50 lc 13 tv 50 ins
There is a flat 3 to 4 ins long sort of ribbon connector made up of abount 20 strands all blue except 2 gold that connects between the engine light assembly kit to the signal board.
it is the only one of its kind in the back of the tv.
I need the correct description of the part and its number to order a replacement.

TV Tech - well another issue has cropped up today. The TV turns on for about 15 secs and then automatically shuts off. Seems like a power supply issue but not sure.. Your thoughts?

Going through bulbs that quickly would indicate to me a problem with the ballast or smps (switch mode power supply). It's not something you want to just run out and replace (expensive).. Call a reputable shop and tell them what you're experiencing.
I do know that they should check the value of C1330 in ballast circuit. If it is a .22uf, There is an upgrade kit available for it, panasonic p/n# LSUC0022

I don't know why that guy told you to replace your "DC" board (that is the one you mean, right?) More likely than not, it's your convergence amp integrated circuits (ICs). I had what I think was the same problem (on the same exact model TV) you described, and I looked around alot of blogs and DIY websites, and this seems to be the most prevalent root behind these convergence problems. I ordered the two chips for twelve bucks (for both), spent a few extra bucks (like $35) on some electronic tools / solder supplies, and followed procedures laid out here at http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-i.html, as well as paying strict attention to the service repair manual (which you said you already have?). The result? No more convergence problem, and I saved myself around $400 - $550 over having it done by a professional.
Seriously-- I bet this is the culprit. Just make sure if you're gonna do this that you FIRST check the six resistors (located at spots D-7011 thru D-7016) to make sure there are none burnt out / opened. It may be that one of those is fried also / instead. Since they are far easier to replace, it's good just to rule them out first.
And by the way, just FIY, when I did this I had kept the TV unplugged for about two weeks first, cuz I wanted to make sure all the capacitors were discharged and safe. Did I need that much time? Maybe not (some have said a few hours is sufficient), but I was also primarily concerned about the Flyback Transformer and its wires, which have the highest voltage (up to 30,000 volts) and can hold a charge pretty long. And I'm still here to write about it. So, check out the link, and see if you'd like to try this yourself, as well!

Enter the tip of a pointed knife between the left side edges of the connector (circled in black in the attached pic) and gently tilt the knife away from the connector. Do the same on the right side. The connector should pop up.

IF it is dust, is good idea asking for and estimate to see if can works.
