The RCA F27242GY uses the CTC185 series chassis. If it blows the main fuse the instant the power plug is inserted in the wall, then you most likely have a shorted power supply IC. This is a large almost-rectangular black IC mounted on the metal heat sink with STK730-020 (or -010) printed on it. Some sets have a metal clip over the top pressing it into the heat sink and some have 2 screws holding it in place. If you change it yourself then you must unsolder and remove the old IC, clean the surface of the heatsink, get a new STK730-020, apply heat sink compound the the back of the new IC, bolt it in place and solder its pins. Replace the fuse again and if you did everything right, the set should play fine.

My 4x4 fuse is poping on my 1994 cheve silverado 2500


a fuse only blows when it is overloaded eg.if you have a 10 amp fuse & the unit it supplying power to is drawing 15 amps it will blow, that is why the fuses are there,firstly make sure you have the right amperage fuse,if it keeps blowing,whatever it is supplying power to is faulty, don't try and overcome the problem by using a bigger fuse as you may start a fire......hope this helps.....cheers

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

What do you do when your amp keeps blowing fuses


First off which fuse is it? The inline fuse from the battery or the amplifiers power supply fuse? Blowing the main fuse from the battery is caused by either the load (your amp) drawing too much current or you have a short to ground somewhere. Maybe there is a tear in the 12Vdc line and it is shorting to the chassis of your car. If the amps power supply fuse is blowing as soon as it turns on your amp has a shorted power supply. This will require internal component changes by a technician. If it is blowing after operation at high volumes I would say change the impedance that the amp is driving. If you are at 2 ohm try to rewire your speakers for four ohm. (go from parallel to series wiring then bridge mono or operate the amp in stereo mode)

Blows fuse when turned on


this is a normal behavior if one of the power supply transistors have blown. take the unit to an enlectronics repair. they can either change the transistors affected (usually more than one) or replace the power supply board.

Blow fuse


If the TV keeps blowing fuses, there most be a short somewhere. Most likely the power supply board itself somewhere. But take it to a repair shop to find out for sure. The sad part maybe that you'll have to pay over $100 for someone to look at it.

Fuse keep blowing off


If the fuse keeps blowing, that is an indication that something has failed and is drawing too much current. Most likely it could be a problem with the power supply, such as a shorted rectifier diode or voltage regulator. Another possibility could be a shorted audio output module. Unfortunately, you'll have to take it to a repair center to be serviced.

Please let me know if I can help you further.

Good luck!

If it keeps blowing fuses then #1 its internally damaged or "blown" .. Or #2 i would make sure you have the battery power hooked up to the + terminal and the ground wire running from the car body to the - terminal.. so if its hooked up correctly and keeps blowing fuses then it requires repair.. I wish i had better news but thats all it can be...
