HDMI Port Not Working After Fuse Blow Due to Missing Earth—Repair Steps for TV

Hello. Im new so I just ask a simple question.

My power outlets dont have earth and my extension cord has earth and - together.

So I powered my tv on and everything worked fine, attached antenna and still everything works. but then I attached my HDMI cable and boom, 16A fuse blew. Removed the antenna but hdmi was still conencted. Then I powered TV on again and attached antenna. boom fuse blew again. now my TV wont reconize HDMI anymore. First it says no cable connected. Then I attach the HDMI cable and It shows No signal. So it reconizes that something is attached but no signal. With other TV hdmi works. I took my tv appart and 2 diodes showed 0.001 with my multimeter so I replaced them with almost same ones. And still no signal. Power board is working fine and I see no burned areas or blew up capasitators. Is it possible to revive hdmi signal somehow?

I am 4 year electical engineer so just tell me where to look or am I missed something.

Hi,

First of all, what kind of TV do you have? The model? This is for easy reference. Second, I doubt that a fuse would blew if you connect an HDMI. The power requirement for an HDMI to work is just so small just like a USB of only 3 - 5 Volts. But maybe your right, It is maybe caused by a power surge from the HDMI. If its true that there are no burnt components, there are suggestions that you may opt to revert to factory setting on your video if there is that option in your TV.
