Hello, I see you were chatting with the site's automated response system. I am Mike, the real life technician assigned to help you. Sorry to hear you are having problems....
Since you have backlights (and audio at one time), and replacing the tcon did not work.... The bad part is actually the Main board, that's the board with all the audio/video jacks. Be sure to get an exact matching board. Let me know if you need help with that, will need the numbers off your current board.
If you need more help or don't understand something use the REPLY option.
I hope you appreciate the answer that I provided so far. All of the technicians here, including me, take your question very seriously because helping you is how we support our livelihoods. Please be aware that every moment spent helping you goes unrecognized until you submit a positive rating for the answer provided.
Please submit a 5 star rating at the top of this page now so that I am recognized for helping with your question. If you are not sure about giving me 5 stars, please tell me how I can possibly change that! If you having issues with the ratings try refreshing the page.
Rating does not close your question or prevent future replies which are at no additional cost. The longer you wait to submit a rating, the less chance I will receive recognition.
