Re: Sony XBR-49X700D: Vertical Lines
You are exactly correct: I damaged the ribbon connectors at the panel when I flipped the panel over. D'oh!
Truly a bummer. I had successfully repaired the source of the "5 blink" code on this TV--a bad LED strip--and in doing so, managed to jostle the panel just enough to break the connection somehow.
Oh well... live and learn.

ID and Sourcing a Microswitch
The microswitch in the image below does not work.
What, exactly, is this type of diminutive switch called? Where might one source such?*

Two boards, left and right, each with six ribbon cables affixed (i.e., "bonded") to the panel.

Re: Sony XBR-49X700D: Vertical Lines
Did that (sans pencil eraser). Both ends. I disconnected the two short ribbon cables btwn the TCON and panel buffer boards and "cleaned" the ends with isopropyl alcohol and a Q-tip. No change to the vertical lines.Leave a comment:

Re: Sony XBR-49X700D: Vertical Lines
Perzactly.
I'd like to fix this two year old TV. I'd like to confirm this TV is irreparable (i.e., damaged panel). I'd prefer to [I]not[/I] spend a few hundred buck on a new TV.
But my time has value.
On another subject...
I read in other forums that the Sony TV "six flash code" is basically a harbinger of death for the affected TV.
In my case with this XBR-49X700D, it began one day with a dark panel and a "six flash code". My problem morphed from one problem (which I seemingly...Last edited by lothian; 11-22-2019, 10:27 AM.Leave a comment:

Re: Sony XBR-49X700D: Vertical Lines
The panel must be removed to access the backlight, and I was especially careful when I removed that thing. Nevertheless, the vertical lines appeared after I put the thing back together.

Re: Sony XBR-49X700D: Vertical Lines
I have no idea what [I]tab bonding[/I] is. But I'm guessing it refers to the hard connection between the many flex ribbon connectors affixed to the panel display. And I'm further guessing a problem with tab bonding is game over.
In any case, I've jiggled, pressed and yanked on each ribbon at the panel with no apparent effect on the display. So, other than palpation, how do test these things?Re: Sony XBR-49X700D: Vertical Lines

Yet another post complaining about vertical lines in an LED...
I have a Sony XBR-49X700D that decided one day to display a black screen and the dreaded "Sony Six Red Blinks". I buried my face in my hands, fully aware that this particular error code typically means either of two things: a failed T-CON board, or (more likely) one or more dead backlight LEDs.
I did the easiest thing first: I swapped the T-CON board... with no change in status. I heaved a plaintive sigh, and began the onerous chore of complete... -
