Roughly about a week ago my pc started to either turn on with a strange static. If i restarted it would start fine. I then turned it off the other night and when i woke it wouldn't turned on. I tried the onboard graphics, changed card and tried the vga slot but none of them work. I eventually gave up and took it to the shop. It turned out it wasn't the pc but the tv. So i came home and tried it on the small tv and it worked. I went to the shop and got a new tv. This is when it started to drive me crazy. It worked for all of 3 minutes before the screen went black and when I restarted it wouldn't come on. I couldn't get it to work on the smaller tv either. I got an old pc out to try ot use that. Last night I tried it it again last night on the small tv on a punt and was happy when it worked. I left it on for a while to make sure it didn't turn off and it didn't. As soon as I tried it on the big tv it didn't work. This morning I tried it again with the same results.I then switched back to the old pc and that wouldn't work either. So i'm losing my mind. I've never heard of it but is there anyway my pc could blow out the tv? Also what is going on and how do i fix it. .
Please help i'm losing my mind!!

what version of Windows and what video cables are you using?
Windows can get confused sometimes when there is an HDMI output available. it will for some reason default to outputting through the HDMI port(s) even when others(DVI/VGA/DP) are connected.
the only solution i've found when this occurred was to connect to the defaulted HDMI output, then while that is still on and working; plug in the secondary display and disconnect the original HDMI connection. it always then auto-switches to the available working screen.
if this was the case you can then choose which is your main display through Windows display properties. and it should stay this way until you attach more screens again.

they seem to have been working on this issue with Windows 10 updates but i had a terrible time with it on Windows 7 and 8/8.1. having a TV via HDMI & a display via DVI-D was a major pain for a while. should be easier to solve if this is the issue since you only use one display at a time.
guessing you are plugging it into the correct output; PCIe slot and not the system's I/O plate? and that you have the proper input selected for the TV? my LG TV needs to be changed via remote to the proper HDMI signal every time i want to use it.
