Question about Flat Panel Televisions

1 Answer

I have a 42" sanyo plasma flat panel tv. I was watching, and all of a sudden the screen went black. I did still have sound. I messed with the remote for a few minutes...then heard a pop...then tv was completely dead. When you turn the tv on, the only sign of life is the little green led light in the corner indicating the tv is on. When you unplug the tv and replug it in, there is a click. Any ideas??? hubby has it tore apart looking inside now.

Hello, you have a (shutdown circut) it happens when the tv senses trouble in the circut.
becuase these type of tv's run hot at high internal voltages parts can become overheated and loose proper resistance or ability to handle voltages that have to reach other parts of the circut and other internal board panels. a shutdown it is for protection. you may want to check your power supply if there was a pop that is something inside that went bad. be careful to touching inside theres is high voltages stored in the components.
i can not tell you specifically what your primary cuase was without your model service manual. no power means power supply trouble.
replace or trace.
what ever blew out cuased the power supply to go bad you will need a service manual to know for sure.
the wise chioce is to have a service center check it for you they will know what to repair or exchange.

good luck hope this helps

42 inch Plasma TV


who ever told you it was a bulb doesn't know anything about plasma tv's
they don't work like that!
it is a digital video processing board that put out the picture
then there is whats called a back light which highlights the screen and has nothing to do with a bulb
you will need to call a tech to come out to determine the exact problem by doing some test
if you have a warranty then use it , otherwise it going to cost to get it fixed!
sorry about your tv
