Menu itself is fuzzy too.

OK it does sound like the t-con board is bad its just the horizontal lines that are causing some concern here, did both the lines and the fuzziness happen at the same time?

Let me check for fuzzy menu. I will be back in a couple minutes.

Yes you need to do these checks or it will lead to wrong diagnosis

Vibrating fuzzy menu almost continuously. 3 seconds vibrating, 1 second off, then repeats continuously.

It does sound like the t-con board is bad,this drives the LCD panel cost to replace this assuming you did this yourself around $80,let me know what you think here

Ask Your Own TV Question
Customer reply replied 5 months ago
Can you give me replacement part number for T-con board?

If a tech done this $250 depends where you are

You can look up the t-con board for this MODEL at shopjimmy.com to give you an idea however I can't give you a part-number because there may be upto 5 variants of the board in the same model,so you have to do this yourself

Ask Your Own TV Question

And you MUST use the part-number found on the original board

Ask Your Own TV Question
Customer reply replied 5 months ago
Is T-con board the one with the Component Inputs / Audio inputs ? Should I get a part number off old board? What will it look like? Number of digits etc.

Each variant will not be interchangeable some may work others will not

No the t-con is usually mounted upper middle of the set and may be covered by a metal shield, the board with AV connectors on is the mainboard

Customer reply replied 5 months ago
I will go to shopjimmy.com for the T-con board. How do I cancel this 7 day trial service?

I am a tech using the site like you are I have no idea what you have been offered you need to speak with support from the homepage about that, I only receive a fee from the site (from your payment) when you rate me hopefully 5 stars with the rating bar of stars at the top of the page, note the question remains open for 30 days
