Facing TV Problems? Ask a TV Technician.
I'm reviewing your details and will reply shortly.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (non the lower left hand rear corner of the TV), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.
Excellent and you're very welcome!
Also, you paid the website a deposit to work with me, but I am not actually paid unless you click a positive rating. Could you do that for me please?
