This usually is heat related. Is the filter clean? The fan working? Otherwise there is most likly a "so called" cold solder joint...where the connection on a board is not positively made...often when it warms up the joint will 'open'..disconnect. This needs re-soldering.

Jvc i art av 36f475: no sound


Good Day sir/maam, my guess are several, lets start at the common ones, make sure that the AV cables are good. you can try swapping cables to make sure. If possible try the cables on other units such as any DVD player. There is a possibility that the sound jack, is bad, try to vibrate the plugged cable, and see if the sound goes back if it does, you need to solder the terminals. Worse is the Amplifier section of the TV. does the TV sound normal on broadcast? check the volume, mute. or the TV setup. hope this helps. if you have additional info please feel free to ask again, let me know any progress. thanks

Jvc i art pro doe not turn on


The clicking sound is the TV trying to restart itself. It generally attempts this several times before giving up. The blinking code indicates the type of error (error codes are documented in the manual for the TV). The most likely cause is a burned out bulb, but could be something else.
If it is a bulb, it is usually replaceable without a service technician, and at a cost far less than $450.
Good luck.

TV SHUTS OFF AFTER A FEW MINUTES


Very likely to be a heat issue, the first thing to do would be to clean the ventilation slots in the back.

Tv turns off by it self


Ours 60" (60P8342) turns off after a short period of time also. My husband researched it online. The cheap solution he was told to try is to unplug the TV (or plug into power strip and switch off) when you are done watching it. A computer board inside over heats and it's a protection mechanism for it to turn off. Otherwise, it's over $100 to fix the computer board.
