I get flickering horizontal (moving) lines. Is this the tcon board. Or something else? Fixable or should I throw away the tv?

Flickering can be adjusted. You have to enter its service mode option do do it. If you wish to get some details; visit the site linked here. Pull up older posts. Surf the site with patience.
Type in the keyword " flickering" , in the search box [at the top right] of the home page. It will make surf easy.

This is the common problem with this model of RCA TV, the problem is not defective LED strips, but the power supply.

You may purchase a power supply on the net, but you can't guaranty that it is a good one.

This is the trick to make this TV work:

On the power supply, locate the R410 100K resister, solder a 220K/0.125W resistor in parallel with it, this will race up the oscillation frequency of the back light power supply circuit & make the voltage stable.

It is not a proper service procedure, but it works for us.

When i plugged it in the lights started flickering and some smoke came out. Now when i plug it in it won't turn on

sounds like you blew some resistors, or perhaps melted something. Take it in to a specialist and get a quote for repairs

Save the time and frustration these units are hard to work on. Make sure there is power to the unit other than that throw it away and buy a new one for $100.

When filled with water & put on to boil it start's boiling as normal then after 10 or 20 secs.the lights inside flicker off and the kettle ceases to boil then the lights flicker back on and boiling...

I think you would only solve this problem by cleaning the thermostat contacts, or replacing the thermostat which wouldn't be worthwhile as it's likely to be cheaper to buy a new kettle.
Besides this , just getting into the kettle needs special 3 tongue screwdriver and then a certain technique to open it up without damaging the plastic parts. Im'e afraid its a throw-away world now and its not good .

I open the fan and again fixed but it doesn't work display open as flickering

Im thinking english second language here so I'm going to have to guess a little.
Sounds like your video display is flickering and your video card had a bad fan.
If that is the case and it overheated it may have popped some capacitors on the video card. you can throw away the card and get a new one or try to find replacement capacitors to solder in. If the card looks really clean then the heat may have damaged something else. Either way the video card is likely bad.
