I lost power on my TV (nothing else on the circuit). Is this a blown fuse?

Hello
Open your TV and check the protection fuse inside [on the power regulator board] is blown up or not. If blown up, repalce it with same type and ampearage. The ampere ratings can be noted on its edge rims. If the replaced fuse again blows Off, make sure that there is some short circuit with the components on that board.
This is the picture of the power supply board to your tv. There is no repair to it. Just replace it as card basis.

Please check for burnt out fuses at the back of the TV. It would be located in the power supply section of the board.most likely you might have blown a fuse/s that's why there's no power.
Good luck and thanks for using Fixya.

Hi.
If your tv is totally dead check the the fuse for blown and power supply cable for malfunction. If nothing problem with them, you've got problem with power supply circuit and suggested to repair it at local tv shop.

If the main fuse blows, nothing works. Not even the dash lights. Look under the seat for the fuse box. Once you find which fuse is blown, then you can trace out that circuit.

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!

check the power supply section" if the fuse is blown check the circuit after it.

The power management and protection circuits have taken over. There is something taking too much current and the protection system has shut the system OFF to prevent further damage ...............if you are familiar with tv service you can check the main fuse that should be close to where the power cord comes in,if you find the fuse blown it needs to be replaced with an exact replacement for AMPS rating and VOLTS rating as well as size,if the fuse is blown black we might have more problems ahead in the circuit and it will blow up again as soon as you plug the tv back in,if it blows again it will need a more involved repair,the problem could be in the primary side of the power supply.......Check horizontal output transistor.............

If you don't have any indicators working, you have probably lost your power supply. With no picture and no sound the chances are you have either lost the power supply or blown a fuse. If you remove the cover and look at the circuit board there is a fuse located near the rear of the chassis near where the power cord connects to the chassis. If the fuse is blown, it is advisable to replace your damaged power cord before replacing the fuse. The cord could have a short and this could create a fire. Be very careful when working on any television. Be sure it is unplugged for more than one day to allow the high voltage to decay from the picture tube. Do not touch the picture tube, it still may have some residual voltage and could shock you. If you replace the cord and fuse and still have the same problem, you will probably find that the high voltage transistor is bad and needs to be replaced.

For starters, remove the back cover and turn on the TV. You should see 8 green LEDs on the circuit board.

You may have lost power for the audio amplifiers.

• blowing fuse is a short circuit problem in your tv.
• please do not replace fuse unless you know the reason otherwise it may damage tv.
• fuse blowing is due to
• main filter capacitor
• power output transistor sort or regulator short circuit.
• good luck
