Turns on green then goes to red and blinks four times done this once before when electricity and cable went out due to weather and now its doing it again

when a television turns off by itself and flashes as you say, it indicates that there is a problem inside the tv. If you keep trying to turn it on you may do more damage. It could be something as simple as a faulty fuse inside. If you have no expierience with electrics I suggest you get it checked out by a professional. I had a similar problem with another tele model and it was the fuse in the back of the tele that needed changing. I did try to this on my own but unfortunatley didn't have the right fuse so i took it to a repair shop and he done it really quickly.

It's a power supply related problem.
The flashing 8 times is a trouble code. A Service Manual for your TV model will have the info on the codes. It could be a bad capacitor or a transformer on the power supply board.If you have some electronic experience, you can find a Service Manual for your TV over the internet. Cost about under $20.

You have a bad main board most likely. You can try unpluging it for 5 minutes.

could have bad caps in the power supply.They will swell up when bad,heat damage.These caps should be replaced with high temp caps.Capacitors go bad in monitors because cabinets are made thincausing less ventilation,more heat.bad caps will have round instead of flat tops
