Hello, I'm Shahid. Sorry to hear that you're having trouble with this and I'll do my best to help

2 short and 5 long flashes of power light is an error code that indicates Panel 12V line failure, it means either 12V from power board to t-con board isn't available OR the t-con board itself is defective.

Please check 12V at PL connector of the t-con board with a multimeter while turning TV power On, if volts are available even for a second then replace the t-con board that should fix the problem. Please click the following link to view t-con board image and part number info...

Similar t-con board would be installed on your TV located under metal shield at the bottom center of the rear of the screen. I hope this info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page so I can get the credit for my work on the website.
Thank you.
