Have TV Questions? Ask a TV Technician
Thanks for TV model number, I'm working on it and get back to you in 5 minutes.
Sorry for delayed reply, do you have multimeter and can check volts inside TV if looking to repair it yourself?
OK, does the TV show Samsung logo screen before it turns Off and back On itself?
OK, - Have you tried to unplug TV and cable box power cords 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?
