Could be.Some do some don't.Some have a circuit breaker. Take the cover off and check. Be careful though as some parts in the power supply can hold a pretty significant charge for quite a while even after the power supply is turned off.If there is no fuse or if you change the fuse and it blows again I would say a new power supply is in order. Good luck.

Lightning damage can do a # on flat panel TV's. The power supply could be damaged along with other boards. The 5VDC circuit will be the only active supply until the set is turned on. Get a diagnosis done

How do I test a High Voltage Transformer on my Vizio VU42L-FHDTV10A?


It could be the main board. The main board controls the standby light on the front of the set. Check and verify that your 5vdc standby voltage is working. Next, I would check the "on" or "ps on" input on the power supply board. When you turn the set on (either my side buttons or remote) the main board should send a 3.3vdc signal into the "on" terminal on the power supply. This "on" signal from the main board turns on the other half of the power supply thus turning on your set. If you are not getting this signal from the main board, I would suspect the main board. To test your power supply, you can simply put a jumper from 5vdc to the "on" terminal on the power supply. Your 12vdc, and 24vdc power supplies should then become active.

E Machine ATX 250 -12E replacement PS


With emachine MOBO's you have to make sure you plug in the 20 pin plug from the power supply to the mobo. Also make sure all hard drives, cd/dvd roms, floppy drives, etc are turned on. Make sure the red switch on the PS is set to 115. Make sure the PS is plugged into a known working outlet. Make sure MOBO is properly in place with all grounds/screws in place and nothing metal near or touching board which may short it out.

You can review the E Machines PS replacement guide here for further instruction.

Good Luck,

Jesse

Want to use the atx-300-12z as a hobby power supply. Need 12vdc.


You're asking for a fire or just burning out the power supply. But,at your own peril, check the yellow wires for 12v or buy a power supply test adapter from ebay. It bypasses the power switch usually done by the motherboard & will fire up the power supply like it was connected to a board. Then test the wires for 12v. Should be any yellow wire,red is 5v. Green is 3.3 or 3v.

Vizio P42HDTV Power on Diagnosis


Relays are the first big clue, triggered by the 5 & 12v supply you should be able to trace back using a dmm and see if you have both of those voltages present... The lead coming from the smps to the y-sus board is a good start. On a Vizio I believe the voltages are listed per pin right on the board...
If you had any kind of relay sound then you could suspect the y-sustain or z-sustain board or something else. With the relays being silent I'd strongly suspect the power supply.

SFX-1211J no -5vdc


The -5 V requirement for ATX supplies was dropped after V1.3. It was used primarily for the old legacy ISA slots - though not exclusively. If you test any contemporary supply made in the last few years if will show a -5 V failure because it just ain't there! Unless you had a really old MB, the supply is probably fine. Look at the 20 or 24 pin MB connector and if there is no line where the -5 would be ( pin 18 ) then you have no problem.
