Picture of Replace the fuse in your TV
Hi guys, recently my second hand TV stopped working. After quick detective work utilizing the vast electrical experience on Google I figured it was the fuse that had blown. I'm no electrician but I like to fix things myself and I'm too cheap to buy another one at Wal-mart. If your TV stops working like mine you can follow these steps to fix it.

Symptoms. My second hand TV (I traded it for a memory card and micro SD card reader) would not come on by either the remote or on switch. It would not light up or make any sounds.
Diagnosis: The diagnosis was that the TV was not receiving any power. After trying different wall outlets, and plugging in known working appliances, I ruled out that it was not a faulty wall outlet. (I would use a lamp but that doesn't work either). No sense in cracking open a TV and risking your life if the wall outlet is not working or not on at all.

Step 2: Step 1

Picture of Step 1
First unplug the power from the TV. Resist all temptation and leave the TV UNPLUGGED during the course of the repair. There is a 120V area on one side and high voltage area on the other side, either one you accidentally bump into is going to leave a big ouch or might make someone rich when they cash in your life insurance policy.

Set the box glass side down. Unscrew every screw and place them in an organized fashion. After you remove the screw, carefully lift the plastic case off the front. Set it aside.

IF you know what your doing you can go ahead and discharge the tube. If your inexperienced like me just wear thick leather or rubber gloves and avoid touching anything other than the edges of the PCB and the fuse.

hi I looking to fix my Samsung tv im not very sure what the problem is all I know is that the lamp burn out after about a month I tired of replacing the lamp thank you
My tv is bought beginning '90's. Does it work for those as well?
Or is this only for those LCD/LED/LASER TV's?

i dont have any flat TV's in my house they are all the old fat style. Replacing the fuse will work for your TV if you dont have any picture or sound coming from it.
If you cant fix it with a fuse then just go on Craigslist or drive around until you see one on the side of the road. Everyone wants the new skinny tvs and just practically dumps their older tv.
Old TVs is a big source of e-waste and I think it is important to utilize existing good TV's as much as possible instead of buying a new high tech TV.

*Thumbs up* Thanks!

Blown fuse is very common reason why TV does not work at all. This is very useful guide since it does not take much time to replace fuse and than you can watch tv on your LCD television or CRT TV.
Nice. Good info. Thanks.

Now I can stay in my room and watch TV instead of having to leave to date women or work on my social life.

Yay television! TV makes living much easier and interesting, especially if it works.

I was going to use my CBRN gloves but they were in my vehicle and I was too lazy to get them.

I have no idea, it didn't even looked burnt out but it started working as soon as I replaced it.
