    Same as all. Started with loosing the picture, but the sound remained. Then the picture and sound left this Earth with no known destination. The speakers thumps, the blue light on the front flashes, then silence. Nothing after that just a stupid flashing blue light on below the power button.

No audio on a hln617wx/xaa

Sounds like a defective main board. Something not right in your audio circuit.

Jvc 56 inch television went black, then a large thumping noise, and I tried shutting off the power and could not, so I had to unplug the television; the television now will not come on.

sounds like the WP30 or WP74 series that has a convergence shutdown which will usually cause the thumping through the speakers. Unplug the convergence power board and see if the set will power up. Do not remove the rear cover the board is up front behind the speaker grille. Never remove the rear cover on a JVC rear projection as it can damage the digital circuits due to the safety interlock on various JVC models.

The tv turns on but there is no picture. just an audio thump thump. like a drum. any ideas

Look inside front panel. Look under right side picture tube for oil leakage on signal board. If you see a puddle and possibly corrosion, then the tv is toast.

Hello, all of a sudden the tv made a fizz out sound

Souns like bad HV transformer. Remove thedeflection board and send it to PTS for rebuild. At this point there are also other components that have failed.

Our JVC 56in rear projection tv cut off and when we tried to turn it back on is makes a thumping sound and the blue light on the front blinks and the thumping sound gets louder... Help??

The problem is one of the video drive IC's on the crt boards is bad. These IC's are located behind the front speaker grille. The board connected to the bottom of the crt's will have these ic's on them. They will be screwed into a metal "heatsink" The part number is TDA6111Q

No picture ... thumping sound from speaker1

Check the horizontal output transistor. If that is good you will most likely need a new flyback
