Apologize for not getting back to you sooner. I have been attending services.

This symptom is typical of a failing T-con board. There is no easy fix like pressing some buttons. The board inside the tv will need to be replaced. The part number of the board is RUNTK4400TPZB. It is hard to find in stock because it is on back order. Here is a link:

I am here to help you. If you need more help reply back. Please be sure to click the 5 STARS or SMILEYS rating now. Doing so does NOT close the question or prevent us from continuing our conversation here. My livelihood truly does depend on your positive rating.

I understand this is upsetting news, but clicking the "bad/poor" rating does NOT do anything to fix your issue, nor does it issue you a refund.

Thank you,
