TV Repair Questions? Ask a TV Technician for Answers ASAP
Hey there! Welcome to Just Answer, an independent, paid-support site. Sorry to hear you're having problems, my name is Wes and I'm going to do everything I can to help you find the information you need.
What is the model number of the TV? The model number is usually on a sticker or plate on the rear of the TV. If there is a product code, version number, or serial number, please let me know what the first 5 to 8 characters are in addition to the model number of the TV. Fuses don't make noise when they blow... the sound you heard was likely a capacitor bursting. That likely means it's time for a new TV unless you want to open the TV up and look for the board with the blown capacitor and replace the board (or the capacitor).
What you will need to do is take the back of the TV and check the boards over for a burst capacitor. Capacitors are the cylindrical components on the boards. Once you find that, make note of the board's part number and purchase a replacement here: https://www.tvparts.co.uk/index.php?route=product/search&search=PS43D450A2W [Click the blue text to visit/view the link]
One of them must have blown.
If you can't find the board, you may have to replace the boards one at a time. I would start with the power board which is this one: https://www.tvparts.co.uk/bn44-00442b-pb4-dy-samsung-ps43d450a2w-power-supply
