Well, you said the contacts were burnt out so that means it is either an electrical short or something overheating on the inside. Have you been near it when it cuts off? Have you smelled anything burning? If so, you will need to get that looked at by a professional and see what they say could be burning (if anything is).

When my unit was set at 120volts...I plugged it into a 250volt circuit ... loud pop ...can it be fixed


Hello, Doing something like that,chances are you blew the powersupply , and hopefully nothing else. You can replace just the powersupply 50 dollars or less, if that doesn't fix it will have have to be serviced.

I have a KDL52s5100 it is not working(no lights, dose not t turn on) due to a thunderstorm. I have bought 2 powersupply board and a new main board and still nothing turns on no even a light.. please help....


make sure that all the voltages in the power supply output are present before connecting to the control motherboard. also confirm that the cables supplying the voltages to the motherboard are all matching e.g do not make a mistake to connect the 3.3v cable to the 12v terninal. just be cautios and your system will power up

Our Polaroid FLM 3232 has worked for four years and now all of the sudden it won't turn on....seems to be no power supply...the red standby light is not illuminated....please help we love this tv!


I hate to say it, but it is prob the main board that went bad. (the board where all the inputs get plugged into) It is possible that it might be the power supply. One thing to check is to make sure you have 25v coming from the powersupply board to the connectors that plug into the main board. If you do have 24-25v than you will have to replace the main board. If not than the powersupply.

DELL HIT BY LIGHTNING, WILL NOT TURN ON. HOOKED UP ANOTHER POWER SUPPLY TO IT, BUT ONLY AN EMBER LIGHT CAME ONE. BUT IT WAS A 20 PIN, AND MY DELL IS A 24 PIN.


you'll need to match the power supply, if it's 24-pin, you need to use a replacement 24-pin power supply, otherwise you will not be able to power up the system. I recommend checking dell's site for a replacement, or tigerdirect for a compatible aftermarket power supply. They're relatively inexpensive.

Hi my samsung lcd tv model le40s8, it won't switch on when i press the power button on the remote the red light starts to flash and it makes a clicking noise and won't turn on


if you can do soldering work, replace two 1000uF10v bulging capacitor with 1000uF 16v or 25v in powersupply board. you will save $200.

RCA TV Model F32444 Will not power on


The noise you are hearing is probably the degauss (it demagnetises the screen every startup). The most likely problem is the power supply. Do a replacement of all the caps on the powersupply board and it will likely fix your problem. Because it still has power to the degauss coils it hasn't blown the fuse. Power supply not starting like that is usually caused by a small electrolytic capacitor near the heatsink on the mains side of the powersupply. They can be replaced for about 10 cents.
Hope this helps

Brand new coolmax cug-950b power supply. everything appears to be hooked up correctly, but it wont power up the mother board


the best thing when you can't see power going through your computer is
1. check the obvious once again (the current setting in the back of the ps.. is it 115??
2. replace the powersupply for known good powersupply.. if it works, your powersupply is defective (likely) if it doesn't your motherboard (unlikely), your memory (likely) or your cpu (unlikely) maybe the one defective.
