It has No Back light, No Image, No Audio but the green power light is on. I was watching TV when the screen kind of glitched or froze then went blank. Nothing since. Your professional opinion would be appreciated. Thank you. Mark Attachment(s) 20170107_110352.jpg
If there is power light at the front panel, the fault is with the main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
If there is no power light too, the fault is with its main power supply regulator [SMPS] board. In both cases, a board replacement is the remedy. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

I checked for back light through back cover in the dark also took back cover off and tried in the dark.(nothing) Looked for image on screen in the dark and even tried a flash light to see if I could see any image.Tried all control buttons to see if anything might show.(nothing) With the audio I could not hear any kind of sound when plugged in and volume on full. Green light on when plugged in. That's all I tried so far.
Will take it in to a repair shop. Cheers
