Fuse blows when it gets plugged in

The tv was not powering on at all and I tracked it down to a blown fuse. I replaced the fuse and when I plugged it in to the wall I saw the fuse blow again. Everything I have looked up tells me that it is probably a bad resistor. How can I find out what all the different resistors are suposed to test at. Or is there a likely resistor that it would be?

Re: Fuse blows when it gets plugged in

No it doesn't sound like a resistor, it sounds like you have a short in power supply, you can look for bad Diodes in bridge rectifier,or solder bridge, or transistor short, start from beginning to end. It is definately a short and most of the time resistors open and this will not cause a blow just a dead set.

Jvc tv av36230 was working fine one day tried to turn it on the next and nothing. its like its un pluged but it is. is there a fuse or something inside?

Yes, TV sets have a fuse inside (in a holder on the circuit board near the power cord connections) and it may be bad, but that's unlikely to be the trouble. Fuses seldom just go bad on their own, and if you find it's blown there's usually some other part that causes it. A dead TV is not always easy to fix, and you generally need the services of an experienced technician with the tools and information to track down the problem.

Have you tried unplugging the TV from the wall, letting it sit for a minute, then plugging it back in? This will reset the computer inside (if it's getting power), and sometimes that's all it takes. If not, you can take the back off the TV (MAKE SURE IT'S UNPLUGGED!) and check the fuse, but that's about all. As I said, if it's blown it will probably go again if you replace it, and if the fuse is good but the set won't come on it will need professional help.

Good luck, and thanks for using Fixya!

Is there a power fuse in this tv. sony 32" 1998 trinitron. Had great color, picture & sound. Will not turn on/no power.

There are fuses in most TV's... and in some cases, it's nothing but the fuse. BUT, the fuses are there to protect the circuits... so unless you know that there is nothing wrong with the TV, you shouldn't simply replace the fuse and plug it back in. However, if the TV is an older TV and it's either fix it by replacing the fuse or get rid of the TV... then I'd certainly take out the screws and check the fuses in the TV. But many times the fuse blows to protect it when something else fails... so if you find a blown fuse, look around for other signs.

WORKING ON ELECTRONICS should be done by professionals!! Proceed at your own risk!

Keeps Blowing The 5 Amp Fuses

There is a short in either or both the main power supply or one of the scan amplifier sections and or the high voltage section.

You will not bel able to service this yourself. This type of repair can be fairly involved and complicated to troubleshoot.

An expericed TV tech should be able to service this for you.

Main fuse blown on CT-32G11 32" Panasonic TV, Replacement fuses continue to blow.

If the main fuse keeps blowing, check the horizontal output transistor for a shorted condition and diodes in that section as well.

On some models the reset is unplugging for a minute or two and plugging back up. Otherwise you have a blown fuse where the power goes in. If you decide to replace the fuse do no go over 5 amps. If the replacement fuse blows there is a short in the set and needs a repairman.

Tv wont turn on

Hello tvlover, The outage actually is not the problem but the spike that happened when your power came back on did the damage. That aside, you may just have a blown fuse. If you are able to and feel comfortable work with electronics, with the TV unplugged from the wall, take the back off of your TV and take a look at the line cord going into the circuit board, this will lead you to a fuse holder, look at the fuse and see if the filament inside has been blown (opened). If the fuse is blown relace it with one of the same amperage and voltage which should be written on the metal part of the fuse. Once the fuse is replaced, plug the power cord back into the wall and power it up. If it comes on and plays, that was your problem and you can turn the TV off unplug it and put the back cover back on, plug your TV back into the wall and enjoy. However if the fuse blows again, that could indicate a problem with a short somewhere in the powersupply path and that will require troubleshooting the set. Now I we have to troubleshhot this TV you will need a multimeter, an oscilloscope, and a schematic of the TV (at a minimum). If you do have electronics experience to this level and do not have this type of equipment, You will have to take the TV to a repair shop. Thank you, and I hope that it is just a blown fuse.

Power surge I think

If you do not get any clicking or sound when trying to turn on the TV set, most likely the main fuse went out. This is almost always due to something else blowing out along or making the fuse to blow out. DO NOT SIMPLY REPLCE THE BLOWN FUSE! If there is other shorts inside the set, and you replace the blown fuse, you can cause more damage to the TV set. The best way to test this set if the fuse is blown would be to hook up a 100 to 150 watt light bulb across the blown fuse, and if there is a short in the TV set the light bulb will glow bright and stay bright. If the bulb lights up and goes dim maybe just maybe you got luck so replace the fuse and see what happens. If the light bulkb stays bright, there is a short in the set somewhere and if you do not have a service manual and a good multimeter and a knowledge of how the TV power supply works, you really should call in a pro to assist you in the repair of this TV. there is just too much High Voltage inside these TV sets to be experieenting around inside of it. Good Luck.

TV does not turn on

If you have no indication of power(no lights,no clicks) the main fuse is a good place to start but if he is blown and is black in color you will have a shorted component ahead in the circuit and if you replace the fuse it will blow up as soon as you plug the set in,in all honesty since you are not too familiar with tv service you should be safe and seek the assistance of a servicer.
