Turn your TV off and let it rest for 15 minutes. Doing so will cool the screen down, making the screen safe to clean.
Use a soft cloth with a mild soap solution to clean the TV. I recommend to avoid use a cleaning solutions as it may damage the screen in the long run.
Please let me know if you require further assistance. Thanks for understanding.
sorry to say, but your best option is replacing the set.
If you can even find anybody willing to try and replace the screen, I do not recommend it. The factory procedure to assemble the screen to main circuit board is complex, automated, and is performed in a clean room environment. My experience is that repairs of this nature will not provide you with the same picture quality, if they are possible at all.
