Question about Televison & Video
I have replaced twice and the same resut fuse and D2498 both gone
If it's not the main board that's causing the fuse to blow then you have a short circuit somewhere in the power supply. Check things like the electrolytic capacitors. The ones that look like little cans. They should all have flat tops. If any are bulging out at the top they will need replacing. Also check the bridge rectifier which is a black component usually standing up on the board with four legs. If there is no bridge rectifier there will be 4 rectifier diodes together. They are black cylindrical items with a sliver band on one end and a lead out of each end. They are usually located near to where the mains lead enters the power board. Other things to check are power transistors, they are usually 3 legged, (sometimes 2 legs if they are used as a diode) black items with their case fixed to a heat sink (aluminium block.)
