We often see these sets develop faults after a few years, and in most cases it requires replacement of a component (the Power Supply Board being the most common).

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.

Simply view my reply and try those steps to proceed.

Were you able to try those steps? Are you still having the same problem?

TV Technician: Aric, Technician replied 3 months ago

If you're still having the same problem, then unfortunately this indicates the set's Mainboard has failed and needs to be replaced. This is a "plug and play" part- meaning no soldering or special tools are needed to replace it. Only a screwdriver and about a half hour of your time. That part can be purchased for your set at the link below for $46:

Alternatively, if you're not comfortable with this type of work, then at a shop this is $200-$250 parts and labor, and this TV can be replaced for that same cost if you went with another RCA. However if you'd like to inquire on repairs, or seek a 2nd opinion, you can use the link below to locate a shop in your area:

Other than that, I'm sorry for the bad news and wish there were a quick fix.

That's bad news I'm afraid and does indicate a hardware failure. Please see my answer posted just above for the diagnosis.

TV Technician: Aric, Technician replied 3 months ago
It's not considered cost effective to repair this set again considering it can be replaced for the same cost. Other than that, do you need further assistance with this?

It's not the power supply- it's the Mainboard I linked to above.
