It's entirely possible that the TCON is causing this, the problem is that there's no guarantee. The problem can also be the panel (the entire screen), and that, of course, would be bad news.
Also, a TCON board is about $76, so even if a tech were replacing it, it's hardly the cost of a new TV.
But if you want to try it, you have nothing to lose (except $76!).
The part number for the board is 1-857-128-12, and if you click on Encompass and log in as a guest, you can order it from them. Note that you will initially have to pay $166.15 for the part, but when they get the old one back, you get a $90 refund.
Best of luck to you, let me know how it goews or if you have other questions, and thanks for using JustAnswer!
It looks like it, but I can't be sure. And I'll bet they just transposed the last two numbers.
Z, I'm afraid the only other thing it can be is the screen, that's what I was afraid it would turn out to be.
A new panel is in the $860 range, let me know if you want ordering information.
Z, I can absolutely positively guarantee you the problem is not the main board, it's the panel.
Sure, but I need the serial number of your unit. Get that to me and I'll be happy to give you the info.
OK, the original part number is XXXXX but my supplier says it's no longer available, and to use part number 1-802-932-43, which they sell for about $528, but apparently they also say there is an equivalent part (part number 1-802-932-61) for $449.
This is available from Encompass.
Best of luck to you!
