SOURCE: No power
I had the same problem and i fixed it by unscrewing and installing the lamp cover on the bottom.. give it a try!
SOURCE: Power supply suddenly 'dead'
You check the power supply using multimeter. but before everything make sure the you are getting power from the power outlet.
Here is how you can check the power supply with multimeter
If the wall outlet and the power cord are good, make sure the connection at the motherboard is secure. Then you may have to face the fact that the power supply itself is bad. If you have a multimeter, you can test the power supply output before purchasing a new one. Simply follow these steps:
SOURCE: Computer will not turn on....how do I check to see
I just went through a heap of troubleshooting with power supply issues before swapping psu's and finding this was the solution to my problem. Had a closer look at my psu that was faulty, the green light was flashing on the psu, unplugged all components and thought that I now had a non-flashing green light on my psu, on closer inspection the light was actually flashing very fast so appeared to be an almost solid light...the psu was stuffed so replaced it and no more issues. If your power supply has a green light check to see if it is flashing when plugged into voltage with nothing connected to it. If it is a solid light then it is probably ok.
SOURCE: My Sony KDL-32M3000 has dark
It will be either BM board (Video Processor board) or Tcon Board (top side of panel). I have similar problem...my TV turns on, lamps turns on (you can see them from back side panel holes) but just a dark blue picture appears with no image (like picture when external input is selected without signal), no OSD appears....some times I can heard audio (using Antena).
I'm thinking getting the BM board.
SOURCE: No Power ...checked power supply fuses ok normal
HI there as per your information all is ok from the out side. But you did not say about power adopter. Its may damaged. replace that and try. If you face same problem then its a printer circuit board short problem. Thanks.
If the engine has no spark, check for
voltage at the coil positive terminal when the ignition key is on. If NO
voltage, then problem is on the trigger side of the coil (pickup, crank sensor,
ignition module or primary wiring circuit).
But If there is NO voltage at the coil
itself, then in that case the problem is on the supply side (the ignition
switch or ignition wiring circuit).
But if the coil has voltage, then problem may be a bad high voltage output wire from the coil to spark plugs or hairline cracks in the coil output tower.------Getting this all possibilities checked will point towards the exact faulty part which is to be replaced.----------This should help.Thanks.Helpmech.
