My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
This sounds like the input is on the wrong one. Press the input on your remote a few times, pausing between each selection to see if the picture comes back on.
okay, press the menu button and see if you can get the menu feature on the screen.
okay, this sounds like a problem with one the main control boards. Try unplugging the power cord from the main outlet for 15 minutes. Then reconnect the power and try powering on. Let me know what happens please.
okay, does the sound come from the tv speakers or do you have an external connected speaker system?
okay, is the video device that you are using connected via hdmi cable?
okay, since the menu function isn't working that rules out a bad cable. The next likely cause is a bad t-con board, after that is the screen itself may have failed. We have seen several of these units with screen failure after two to three years.
The t-con is not very bad(around 100 GBP), if it is the screen then it will be cheaper to replace the tv.

Do u mean the tv issue?
Yes, if you want to test the tv to see if it id a board or if the screen is bad I can help, you will need a voltage tester and be comfortable taking the back off of the tv.
or if you want to have a local repair shop to check it I can find the closest one for you.
