TV suddenly stopped working

@gosu_d first use your multimeter and check the 1.fuse for continuity. No power to the TV (keep it unplugged). Use a multimeter put in on the ohm scale. Then place one probe to the left side and the other probe to the opposite side. If the needle (analog meter) move than you have continuity. A digital meter will show continuity as well. Next test is a bit more complicated since you are going to test a live circuit. Use you multimeter and place it on ACV (250V) scale. Plug your TV in and see if it turn on. Yes/No don’t matter since you will still have power going to the connector on the power board. Careful now since this is a hot area. Do not touch anything with your fingers etc. Use the black probe on one end of the fuse and the other on the neutral contact of the connector. You should have common household voltage on there. After that you want to check the 2. connector and see if it has something listed a power STBY. If so you want to measure that as well. This will be DC voltage so set your meter at something like 10V or 50 V DC scale. To measure that place red probe on the Stby contact and one to ground. Any screw that mounts the power board to the chassis will work. With all that let us know what you get. It sounds like a lot and a bit complicated but it really is not. MAin issue is keep your fingers/hands of any contacts on the board. even after you disconnected or turned the TV off. The large capacitors on the power board will still be charged and you could get zapped. Not pleasant :-)
