Ouch that sucks.
If that plasma is generating enough heat to compensate though, it might be time to look into a TV that is more efficient.
Had my furnace stop working last year in January, but sometimes it would eventually start. Then it got to a point where it just flat out would not start which sucked in the morning when I woke up to it being like 10 degrees. I decided to diagnose further and found it was the pressure switch which was an easy part to temporarily bypass till I can replace it. Replaced it and it's been ok since.
Blower is a bit more involved though.
