Sounds like fluorescent tube has gone, but you say this is LED? Newer tvs are LED. What you have, may be LCD, in which fluorescent tubes were used. You have no recourse.

Sounds like a bad lamp to me

Your ocilater on your main power board has gone bad it should be on a heat sink with 2 other oscilaters. Please have tech check it and replace it.

Sounds like a problem I had with a Polaroid t.v. Take the cover off the back and look for capactors that are buldging on the top. The top should be slightly concave. If they are convex at all, you can buy new one at Radio Shack and replace them for under $5.00

When the tv goes to a black screen does the sound remain on? Also,if you listen carefully can you hear any arcing noises in the back of the tv?

my first question is have you checked the bulb. the loud pop sound like the bulb blew and the rattling sounds like the lamos trying to fire. remove the bulb cover and unscrew the bulb

someone shot your tv.





no really, I am just a smart a$$ --- but the loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..
