Re: Samsung PN50C450B1DXZA Screen flash, red LED blink, Logic Slow Blink

Thanks Awyatt! You basically said what Alastair said, but the part about the boards having nothing to do with it was a little more e guidance. I was still under the impression something was causing it at the board.

Alastair.... Damnit man. That's an in depth reply. And I know you know your shit. I wish you had just said that earlier! Haha.
So, vertical red lines in a plasma are not fixable with a replacement board and are due to a bad COF. That's_______ on film... Right?

That's...

Looks like I'm not going to get any other information out of the community =/

I was hoping for some insight and not just a "throw it out" answer, unless it really is worth nothing. The boards are cheap, so I hate to throw it out if something board-wise can be replaced and clear up the issue.

I was saying that I was just asking for more input on the symptoms and possible issues. It seemed that the vertical cool bars could be fixed with the Ysus board and y main board being fixed.

Just looking for information. Not really just a "scrap it" type deal. I'm trying to learn as much as I can.

And as far as Alastair's word, I was saying that it's not a matter of it not being good enough or incorrect or that he knows nothing. I'm just looking for more. I'm sure he is...

Anyone else? Not to say Alastair's word is not valuable or correct... I'm just curious on the thoughts... Is it really a complete scrap case? :/

Hmm. That's disappointing. I reviewed my photos I took and left everything taped in place.... Its pretty impossible to route cabling anywhere else since they taped so closely to the connectors.

My vertical colored lines appeared the same as this, just not in the same quantity.

Model: PN50C450B1DXZA
Symptoms: Colored thin vertical lines in two places on the right side of screen. One approx. 2 inches wide and the other maybe 1/2" wide. Developed a different issue upon reinserting the cards. Upon power on, screen flashes brightly, then solid black. Red standby LED light flashes red 5 times and stops. Logic board light flashes about 5 seconds on, and two seconds off.


So, I was messing with an old TV that got lines in it a few months back since I have some extra time on my hands. I have read just about every justanswer reply, badcaps article,...
