I have a Viore 42" plasma with no pic but has sound

Sounds like main board fault. Contact any "Experienced" service technician, or, the authorized service center for Viore.

Is this problem occurring while watching any channel or while playing any DVD?

check first at the sound set up menu might set to off. if the settings is ok and the speaker is also good, the cause is either bad amplifier circuit or sound processor at the main board. at this time you will need a trouble shooting.

speakers switched off?
volume on set or a box down or muted? check both the set and box.

Does the set have normal sound when playing a DVD etc via the audio and video jacks on the rear or side?

Hello kdmuszik,

Welcome, and thank you for using FixYa!

Your issue is with your Tuner Board. This piece will have to be replaced. All commands for picture ratio, color, and size transmit to the TV through this board. I have inclusded a link to the board you should be looking for, below.

Have a great day!

Check high voltage circuit. This is near where the 120 volt cord is plugged in and a high voltage transformer, where there should be capacitor (or two). Check the voltage - should be 390 to 400 volts. If not less than 390, near to replace the capacitor.

The tv was working fine until this morning, then the picture went out but the sound is still working.
TV is only 3 years old, no real electrical problems

the sound suddenly stopped working on my Viore 42" plasma.

The video IC module seems to be giving problems. Open the back cover and take a peep inside. Look for the module just short of the screen. replace it if need be.

19 in wont turn on. red light just solid , unplugged for a day still same , is there a reset button
