Facing TV Problems? Ask a TV Technician.
Hello, I'm Shahid and will be happy to assist you. I need additional info to troubleshoot the issue. - Does TV screen glow/ show backlight or any graphics appear when turn On the TV?- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?
OK, turn On TV and playback a disc in DVD player, press Input button on TV remote several times to change video input source in TV, do you get sound of DVD playback in TV?
OK, have you tried to unplug TV power cord from wall outlet for 10 minutes to reset, replug back in and check?If not yet, can you try it now and reply back with the result?
ah OK, based on TV symptoms it seems BE2 Board failure which process video/audio signals in TV including menu graphics, it is the board that has couple of HDMI inputs and replacement of BE2 board will help to resolve the issue, required BE2 board part number is ***** that can be used to search/ google to get price and stock info to order it.
Please check following link to view the board image which will help to locate it in TV..

Sound output chip is located on AV board where AV inputs are located but processor is on same BE2 board, we tried to switch AV inputs of TV to get sound of DVD playback but it didn't work that means sound processor may not be working any more along with video processor on BE2 board and this board replacement is required to get picture and sound in TV.
I wanted to briefly follow up with you and see how the info worked, and see if that accomplished what you were looking to do!
Please reply back here if there is additional questions.
Sorry to hear that, let me send this question to other experts to have a look and hopefully some one will soon respond to assist you. I'm opting out, please do not rate my answer and leave it as it is.
Is this the behavior of your TV model??
SYMPTOMs -- No Backlight, and Green Power LED lights, but won't BLINK, nor will it activate a FAIL code (red blinking). Backlight ON control line never switches to 3.2 Volts.
Oh and I am NOT ready to be rated...Just answer locks my box so I can't turn it off. I'm just asking questions to be sure that I have your answer correct.
The lights are the KEY to analyzing this.
