Ok, so about 3 days ago I was running my computer through an hdmi from my r9 270 to an Emerson tv. Then a power surge occurred and my tv was fried, no light, nothing. The day after I went and replaced the tv with and Element 32" and as i was plugging in my gpu, boom, a huge spark comes from the hdmi to the tv and fries that one too. Luckily, it was under warrenty and I got it replaced. I went and got an old 24 inch tv and plugged my gpu into the tv, but no matter what I try, there is just no signal. My pc doesnt have a vga and I dont have any dvi displays so I cant actually see what is going on. The fans on the gpu turn on and the pc seems to be running fine, but I have no video output. Is my gpu damaged? Also, I have tried 3 different hdmi cables (in case that helps). thank you for any help in advance.
