Re: I was watching TV and it just cut off. There is no...
Good day sir/maam, chances are yout tv just blew a fuse, when a fuse blew up, there are several reasons.
- It protects your tv from further damage.
- a part of your tv got bad, causing it to blew.
You have a choice of calling your service center/dealer or do it your own.
If you decide to do it yourself, these are the steps you may need to do.
- Open the TV's back cover, to access the circuit. locate the blowned fuse.
- you may need to pull out the entire board, to test it.
- test the switching regulator IC/transistor for shorts, (you may need a multitester).
- check for open low value resistors, less than 100 ohms.
- You really need to find the cause of the blew up fuse. part by part checking is necessary,
- replace the bad parts and test again.
- if everthing else fails, you really need to call your service.
note: if you simply replace the fuse without tracing the blew up shorted bad part, chances are the fuse may blew again.
