Re: Where are the fuses in this tv
That is the only fuse. Its purpose is not so much to protect the
TV parts but to establish the UL rating by protecting against
overcurrents and fire.
Next thing to check is the B+ voltage (125 to 160Vdc) on the big
electrolytic capacitor near the power entry. No volts here tells
you the problem is before this in the power supply parts. After
here means the high-voltage supply.
Check that and get backl to us.

Hello Check the On/OFF switch first. Then check the AC cord. If both are OK, open the TV, and check the fuse. There is a glass cartridge type, replaceable fuse on the power regulator section. If found opened, replace it with same type and number.
Yes, it will certainly have a fuse, probably near where the power cord attaches to the main circuit board. Be careful if you open it up though. Even if you unplug the set, you can still get a good shock from the set's capacitors.
Yes you can change out that fuse yourself just be very careful and have the tv set unplugged at all times while you are changing out the fuse.Remove the back cover to the tv set, once removed look towards the power supply where the power wire is coming into the pc board the fuse is right next to that, once you have found the fuse take it out and check it make sure that it is defective sometimes the thing that happens with old standard tv sets is that a component will give out because of the years that it has been working so this problem can also be caused by a component as well.Ok lets get back to step one if the fuse is defective on the side of the fuse on the chrome part it will tell you the voltage and the amps that the fuse is rated at,remember that when you go get a fuse at your nearest electronic store that the voltage and amps are identicle the same as the fuse that you are taking out.Put the new fuse in and the back cover back on and your tv set should be working back to normal in no time thank you.
take the back off the tv and inspect the glass fuse off the ac power cord, it will probably be black and open, this is a common problem, it blows because the degaussing circuit works too slow, the original fuse is an 6.3 amp fuse, you need to replace it with a 6.3 amp slow blow or a 7 or 8 amp fuse to keep it from blowing, if you put an original 6.3 amp fast blow fuse in it, it will work for a while, but will blow again someday.
You will need to remove the back of the TV. Don't worry, it's not that bad.
There are 4 screws across the top, one on each side, one right next to
where the power cord goes into the back of the case, and the two more
by all of the video connections **These are the most important to
remove because they attach the main board to the back of the case.
Once you have remove the screws then the entire back of the set will
slide off. If you look where the power cord attaches to the board you
will see a small fuse. This is a 6.3 Amp 125 volt fuse. You can replace
it with a 6.3 Amp 250 volt fuse from your local Radio Shack. A four
pack costs between $3 and $5.
Make sure that you check that it works before putting it all back
together. Check for any loose connection cables while you're back
there. I found a few when I did this.
can u do repairing or have you ever troubleshoot the issue by yourself. if yes, then open the cover and check the continuety of the power cable because it can be the damage cable. if all of then check the fuse inside the circuit board where the main power cord goes. the must be a glass fuse. Check is it in working condition means having continuty too. if this component is ok then u have to check the other circuitry.
You'd better make sure that there's no power on in the TV by checking the red light in front of it. If it's sure there's no power when the TV's plugging in the outlet, then the problem may be the fuse.
The GLASS fuse locates right after the power cord where is connected to the TV. Using a screw driver to open the back (make sure the power cord already taken out from the outlet !), try to have the power cord side opened as wide as you can. You can use your finger tip to push straight from bottom to up to take the fuse out. For sure, you can see the fuse having the core disconnected in the middle.
To my case, the fuse was 6.3 Amp and 125 Volt, but I can only get the 6.3 Amp- 250 Volt at my local Radio Shack store. However, it's fine to replace with this higher volt fuse.
It costs about 4 bucks for a bag of 4 glass fuses. Worth to try with the "practice" and for having your TV back on again !
In most cases, it is either a shorted component in the power supply or a shorted horizontal output transistor.
It will take experienced electronic troubleshooting to fix it.
TVs have lethal voltages (both 110V and 25,000V kind) and improper repair can result in shock, injury, or the emission of X-rays by the TV!
Be safe and either replace the set or have a shop work on it for you.
