Hi,It seems that there is a Problem with Power Supply Failure.
Unplug the TV for Few Minutes, say 30 minutes and then Turn it ON. If
Problem Persists, you need to Open the TV as it would be an Internal
Failure.You need to Open the TV. Make sure it would be
Unplugged. You need to Take all the Precautions. Locate the Power Supply
Board. Remove the Connectors and Pull out the Board. Once you Pull out
the Board, with the Help of Magnifying Glass, locate Cold Solder Joint.
If Everything is OK, then you would Locate Bulged / Leaked / Swelled
Caps. They would have Ammonia kind of Odor. You need to De-Solder them.
You could take the same to Radio Shack / Fry's / Order Online. Once you
get the New Caps, Solder them and it is all set.You also need to Check
Fuses around that.If the Problem Still Persists, get back to me
with Make and Model we would Troubleshoot other Components.Let
me know, if needed further assistance.Hope i helped you.Thanks
for using ' Fixya ' and have a nice day!!
