If you own a FLAT PANEL and POWER SUPPLY section keeps blowing the fuse , check the voltage regulator ( IC ) AND CAPACITORS , beware that most of the manufacturers have control of their own parts , meaning that you ll end up buying the POWER SUPPLY SECTION, Good luck , AJ

Somewhere up the circuit something went bad and is throwing to much voltage when it shouldn't be. Possibly the AC-DC converter went out, or is on the freak out.

My Panasonic tc p55st wont power up.


Bad power supply circuit board. (very common).

Ps... Many have a fuse on the board, but then you need to know why it is blowing. If you use a bigger fuse you _will_ blow the board or something else.

With that said, you _could_ try replacing the fuse and/or even try a ''slow-blow'' fuse, just as long as it is _exactly_ the same amperage fuse.

Wy fuse keeps blowing


Fuses blown when an overload occurs. More often than not caused by a short circuited transistor in the main amp section. Possibly also on the power supply too.

No power or light, plus power supply keeps blowing fuse


you have a short most likely on the power supply but could be on the mainboard, inverter board, av/input board. The T-con board is fused and should blow its fuse before blowing the fuse on the power supply. I'm going with a faulty power supply, most likely a shorted Mosfet.

the power board is what is my concern here.

Things to check

Black screen no video no audio suddenly now


This set is a 50" plasma. first check the AC power fuse on the filter board then: if it is bad: check the power supply by marking and, removing all the cables; (so you can put them back in the correct spot) except the filter board to power supply cable; that connects to the Power supply board. Then: replace the blown AC fuse and, re-power: If the power supply blows the fuse: again, the power supply is bad and, must be replaced or, repaired. If the fuse does not blow: turn off the set then: on again, reconnecting and, disconnecting each board cable in turn, untill the fuse blows again this cable leads to the bad board; replace or, repair the board that blows the AC fuse every time the bad board is connected, irregardless of which other cable to the power supply may be connected also; or, not.

Blown fuse on a ilpi-009 power supply


hi, i don't know the exact power board you speak of, most fuses for power supply protect ac inboard power, and backlights. if backlight inverters touch ground or ground out, this will blow fuse. otherwise, the fused circuit is used for main inboard power going to primary capacitor. take an automotive fuse holder and solder test leads long enough to work with, install 4 amp blade fuse and jumper/solder the circuit to the fuse on the board and power on the monitor. if all goes well, probably just power surge or outlet grounded. if blows fuse, check to board for obvious burns or blown capacitors. if not there, unplug backlights and power on, if still blows, check to make sure no direct conact with board and back of screen. just be thorough about looking carefully for shorts if there is one. and don't forget to replace the factory fuse on the board with the correct one after you finish repairing, don't leave that automotive fuse in. good luck.

Hi i changed colour cartridge tried trial run printer died; changed fuse in plug; still no power any suggestions please


in the printer there is a power supply board.there is a same type of 3amp fuse on the power supply board.if there is any kind of overheating in the power then the fuse in the plug and fuse on the power supply board blows out.in some cases only fuse on power supply board blows out.this fuse is placed on the board for safety reasons.because in the older model printers when this short circuit problem was happening at that time whole board used to blow out.so in the new model of printer a fuse is placed on the board ,so if any overheating or any power outage or any short circuit occurs.the fuse blows out instead of whole power supply board. You just need to replace the fuse on the power supply board by disassembling the printer.the power supply board is the green color square shaped board.its the board to which your power wire of printer is connected. the fuse is available at any local electric hardware shop.its not any special kind of fuse. This will help. Thanks please keep updated. please please do rate the solution positively .thank you for using fixya
