What's the model number off of the back of the TV and how old is it?

Tv is like 7 years old
TV Technician: Aric, Technician replied 1 month ago

Thanks for the reply. The green blinking light on a Mits LCD indicates a fault of the Mainboard and generally requires replacement of that part to fix the issue.

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.

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

Tried the steps listed. When I turned it back on, green light was still flashing
TV Technician: Aric, Technician replied 1 month ago

That's bad news I'm afraid. Please give me a minute to type this up.

Unfortunately this indicates the set's Minboard 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 $55:

Alternatively, if you're not comfortable with this type of work, then at a shop this is $250-$300 parts and labor, which is typically not cost effective as a brand new 46-50" LED Smart TV starts at around the same cost. 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.

What do you mea by minboard?
TV Technician: Aric, Technician replied 1 month ago

That was a type. Did you click on the link to the part? It's the "Mainboard".

"Typo". Ugh. Sorry.

Mainboard can be purchased for $50?
Just want to be sure?
TV Technician: Aric, Technician replied 1 month ago

Please scroll back to the answer. Click on the link I provided above. It takes you right to the "Mainboard" for your TV (your model is listed). The price on that part shows $55. That is the board that's needed to fix the TV.
