Tv powersupply fuse is blow, replas new fuse but same problam.
There is some short circuit in the power retulator side of your TV. Never put a fuse and switch it ON, as it may damage more components in your system. A power voltage surge can damage the regulator side of your TV. There is a short [Direct short] occured inside it. Check the rectifier section first, with the help of a multimeter set to Ohms range. Measure the resistance accross the main filtler capacitor. if it seems to be very low, say less than 12 Ohms or so, resolder out the mains rectifier stalk, or diodes, whichever may used, and chck it for juction short. If shorted, replace it. Check out the switching regulator also. In most cases this regulator may get damaged due to power supply spikes. In some sets, there is a MOV [Metal oxide veristor], connected accross the main AC line, after the switching point. this component is used as a protection, and if there comes any overvoltage or voltage spikes, this veristor will get shorted, blowing off the fuse, and further damage is prevented. Check this also. This component will look like a disc capacitor, normally black or green in color. Check these, and further check most of the power regulator components, such as Zener diodes for short. Before switch on your TV. make sure you have tested all the componets in the power regulator side. OK.
