Hello, I'm Shahid. Sorry to hear that you're having trouble with this but I'll do my best to help.- Could you please get me the model number written on back of TV?- How old is the TV and how long it have had the problem?Thanks.
Thanks for the info.
Does power light on TV blink in specific pattern when TV refuse to switch On?
OK, have you tried to disconnect TV power lead from wall socket for 10 minutes to reset, replug back in and check?
OK, solid red power light doesn't indicate any trouble in TV so have you tried to press power button on TV itself or put new batteries in remote that you use to operate the TV?
This is odd symptom, does TV screen glow/ show backlight or any graphics appear on screen when switch On the TV?
Unfortunately it seems hardware related failure and either power supply board or main board of TV has got internal failure which is causing the problem. It needs further troubleshooting with multimeter after removing back cover of TV to check output volts of power supply board which will help to determine what board is bad to get it replaced and this will fix the TV problem.
Please reply back if you have multimeter and can check volts on circuit board in TV to assist you further and if you are uncomfortable working on it then local TV repair shop will do this for you. 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. Thank you.
This is strange symptom, have you tried to press power button on TV itself to switch it On?
