Have TV Questions? Ask a TV Technician
Hello, Sorry you're having problems. What is the model number off of the back of the TV please?
Thanks for the reply.
Offhand these symptoms would point to a hardware issue with either the power supply or the mainboard of the set. In many cases, once these sets get on in years (yours is in the 5-8 year range based on the model) these components are prone to fail and need to be replaced.
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), 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.
If it is hardware, then you're generally looking at between $250-$275 parts and labor, with parts being hard to find (most are used/pulled) and it would be more cost effective to put that same money into replacing the set versus repairing it.
I'm sorry to hear that and that would be money better spent as a brand new 46" LED would cost about the same as repairing it.
Other than that I'm sorry for the bad news and wish there were a quick fix.
