SOURCE: Turns itself off
Sharp LC-13AV4U - turn it on and in ten seconds it turns off.
Happens every time.
DO THIS AT YOUR OWN RISK!
This is NOT a fix, this is a permanent band-aid.
All you need is a phillips head and tiny diagonal cutters....
Heck, even a nail clipper would do it.
Just disable that faulty protection shut-down circuit!
Remove all the screws from the back cover
and look at the main board with the
unplugged! power cord towards you.
In the upper right corner of the board, you will find
a tiny red-striped zener diode, labeled as D409.
It is to the right of an electrolytic capacitor marked C403.
Snip this diode, at either end, or snip both ends and discard it.
Re-assemble the TV.....and you just got your tv back!.
I only run mine when I am sitting in front of it,
I never leave it running unattended....just in case!
Don't blame me it yours burns up....but mine is just fine.

The bad news,your set needs a new inverter board installed.With persistence to sharp,you might be able to get them to pay for the parts.

Aquos has the same problem. I'm not sure how I discovered this, but
when I lean the TV forward and hit the power button it will turn on
every time. If the screen blacks out and I don't lean it forward when I
hit the power button, the screen will just remain blank. It is very
weird, but at least repeatable.
- Thank you, Guest. That did it. It definitely seems to be a problem with the TV. Tilting it and hitting the power button helped me get the video back.

Your control board seem's defective or the inverter board (associated circuits) are bad. This is common in most TFT-LCD Tv's.......

I have had exactly the same problem. Sounds daft but by not using the remote, and only using the power on/off switch on the TV itself, it is working perfectly...no idea why
Use the remore for changing programmes etc but not for on/off
Try it anyway because I know how annoying this is
