So first check voltage at the main input ON the power board next to the fuse, If you have voltage there then either your test on the fuse was incorrect OR there is a broken joint either at the incoming side of the fuse or at the terminals for the Main input OR your meter/leads are faulty/set incorrectly
voltage at the main input of the PSU measures 240V. I then place the red probe on both ends of the fuse and the black probe on the ground and measure both sides as 134.4V. Long capacitors still 0V
Ok this is the point a Schematic would be very handy but not finding one anywhere.
You will need to get a good clear photo of the underside of the power board so it is possible to see all traces and read and markings clearly.
I am useless at tracing out circuits so someone else will have to take it from here, our member budm is very good at this and hopefully he jumps in when he comes online.
hi newtothis, thanks for your patience and help in guiding me to check on my PSU. i'll have to continue tomorrow as it's almost midnight here in Singapore. Gotta rest now and work tomorrow. I'll remove the power board and will try to take a clear picture of it and hopefully budm will help me out with it. Thanks again
There is a secondary side of the power supply, marked with that thick line. You use the black probe on the mounting screw. On the primary side, the black probe, goes to the negative of those big capacitors.
hi tibimakai, thank you for your suggestion but is it possible to circle on the board so I won't make any mistake as i'm a noob in troubleshooting tv. Thank you.
