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.

The red light on my Memorex MLTD2622 does not shine and the tv doesn't even come on anymore how do I fix it


Aside from checking you have power to it and the fuse inside connected directly to the cord is good:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Tv was working fine yesterday. got up today and nothing.


Dear,

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.

regards,

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 !

Not turning ON, fuse blows.


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. I'm a tech with over 25 years of experience, by the way. I appreciate honest rating of this reply if you find it helpful.
