unplug TV and Bluray power cords from wall socket, replug HDMI cable in both units, replug power cords back in, turn them On and check.
Let me know how it worked. it seems Bluray player set its display resolution bit higher that TV doesn't support.
Please connect Bluray in TV by usual AV cable (yellow-red-white) and go to BD player setup menu and reduce HDMI Out resolution like 1080p to 1080i, then check it in TV HDMI input.
If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ Line faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent. Faults to all LCD & Plasma screen are similar, irrespective of its brand and screen size.
Bright and dark spots on screen might be due to the fault of the screen itself. In some cases, it will be reparable. Contact any service technician, because, if it is a repairable fault, the panel might need to disassemble.
For problems which are potentially heat related like this one appears to be, you can try a few different troubleshooting techniques which may help you narrow down the problem to a specific component or circuit board at least.
When you first turn the set on, before the screen artifacts appear on their own, you can use a hair dryer to artificially heat up certain areas on the circuit boards to see if you can induce the faults to appear earlier than usual.
Once the set has warmed up and the faults become visible, use a can of compressed air cooling spray to cool down specific areas on the circuit boards to see if that makes the artifacts disappear temporarily.
By systematically heating or cooling the various components and circuit boards you may be able to isolate the general area which is generating the fault.
Do not forget to test the TCON board as well. It seems to be the most likely suspect, even if you did just swap it out for a new one. It would not be too unusual to get a wonky board which is DOA right out of the package. You must remember that most spare parts for LCD TVs that you order online are just salvaged out of other broken sets with "unrelated" problems.

I believe this is a decoder issue, you need to get is checked by a qualified repair tech. and get it replaced/repaired. If the decoder is fine then unfortunately you need to get the main control board replaced.
Please do accept the solution if the issue is resolved or else revert for further assistance.
