Tv sparked when plugged in
Hi I have a pretty old tv its a samsung LE32A456C2D Its worked great for 10 years until i decided to plug it in with a different cable. As soon as the cable went in a bright white light flashed from behind the tv and it made a loud noise. This also tripped the electricity in the house. I cant see any burn marks around the cable or the back of the tv I took the back off the tv and I saw a slight black mark on the powersupply im a complete noob to electronics so im not sure if this is normal or not. Is it safe to try to turn the tv back on with its original cable
Any help would be appreciated
