Hello,
I turned the TV off at night and tried to go to sleep. Everything was
working perfectly with the TV and it had been working perfectly that
way since I bought it (9 years ago!). There was no malfunction
indication of any kind (bad picture, bad sound, smell, etc.) before I
turned it off. After I turned it off for no more than 5 minutes, I
heard a loud sound like something bursted (sounded like "pak!") and
there was burning smell coming out too. I believe there was a flashing
light coming out too -- but not sure because my eyes were closed and
the loud sound may have caused the brain to imagine the flashing light.
It was late at night and I figured it must be a blown capacitor or
resistor. In the morning, just by curiosity, I tried to turn it on with
the remote controller and it didn't turn on. No sound, picture, red
indicator light, or relay clicking or anything. I tried to push the ON
switch on the unit directly and there was nothing -- complete quiet.
Obviously there was no power feeding anything. I made sure by
unplugging and plugging in. While plugging in, I observed a small spark
at the outlet too (just like when you plug something in and you
occasionally see a small spark). Looks like there was still power
circulating on some part of the circuit.
I opened the back cover, removed the circuit boards, and tried to find
a blown component. I tried for a few hous but to my surprise, all
circuit elements appear to be 100% inact! The only fuse in there is
also not blown. There was no indication of what may have bursted at
all. Everything looked clean or evenly covered with a thin layer of
dust. The picture tube and the copper coil looked ok -- no burn,
broken, or anything. Do you think it's the flyback transformer? From my
understanding, it generates most of the other voltages used in the
unit. Or anything else I should be looking at? I'm still wondering
where the burning smell came from. Thank you!
