My AKAI PDP5016H 50" plasma TV turned off suddenly and wouldn't come back on. When it happened we heard a "Fizz" or "Pop" sound. I took it apart looking for a bad capacitor or obviously fried component. When powered on, not even the standby light would come on. When I couldn't find anything wrong I called my electrician neighbor who looked at it with the power connected and started looking at the fuses and started jiggling cables.

When he jiggled one of the cables, the TV came on! It was a bad cable connector on a power supply board. Look at the photos to see the problem:

The circled area is the problem board and on the second photo the arrow points to the power connector that was bad.

Disconnect the bad cable and find a connector that is identical (try RadioShack) and replace it.

Now I hate to tell you that the solution was to open up the back of my TV, connect the power, turn on the power switch, and start jiggling cables - But it was! You may get yourself electrocuted or worse by doing this, so BE CAREFUL!

Here's a clue: on the bad connector on my TV the connector itself had become discolored brown as if it had been cooked or something. Once the my electrician buddy jiggled that cable the LEDs on the main power board came on and the TV made it's characteristic "coming on" noise. In your instance it may be a fried cap or a lot of other things. Keep an eye out for anything that looks out of place or funky.

While I was watching my Emerson TV I heard a loud click and the screen went black and audio went off. When I press tv button on cable remote the tv button glows red, and nothing happens on the tv.

Hi the power supply might have shut down through overheating turn the power of at the wall socket & wait for a short time before trying again the TV might reset itself if this doesn't work its probably shut down from a faulty component. good luck

I have a Vizio p50hdm while watching heard a pop noise and tv went out cant turn back on.I replaced main board and power board and still doesn't come on any Ideas?

The power amplifier chip (which goes "pop" when it goes bad) may be located on the board where the IR sensor is. Sometimes (but not always) you can make the TV come on by holding the power button in _until_ the TV comes on. But that usually only works when the chip is "going" bad. If you heard the pop, it's probably shot. Also, check for a fuse on _any_ of the boards, and possibly a main fuse at the back of the TV.

Heard pop an my panasonic tv shut off. can't get it to turn on again

Power supply is suspect number one---in most cases there will be a for example 10 blink code from the power light---damage to the board may be hidden from view--so even if looked at you will see nothing.

Watching tv. heard a loud "pop" and the power shut down. got nothing. have the tv apart now but i cant seem to find the problem...any help?

If you heard a "pop" usually thats a good indication that one of the capacitors blew. Make sure that all of the capacitors are smooth on top and not bulky and check around to see if any leakage happened. This happened to my kdl-46z4100 and saw that it was a capacitor that i recently changed that had popped, reason for mine popping was because I had shorted it by using too much solder on the joints which created a bridge and it recieved more voltage than it would handle. That being said, just make sure everything is in order and hopefully its just a capacitor that went bad. Good Luck!

Pop sound then no picture, just sound

I assume this is a plasma TV? You will have a fuse blown on either the Y or Z sutain board, there is also a possibility one of the driver IC's has blown on the buffer board, this will shut down the screen & leave the audio working normally. You can check these boards which sit on the left & right hand sides of the screen.

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...

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
