The front panel has a blue light and power , but i am not getting a picture or sound.


The blue light on the front panel merely indicates that power is getting to your TV. It is likely that there is a failure of the internal power supply

I have sound but no picture. What is wrong.


In order to ensure, it is not caused by the input device, connect a DVD player and see. Switch off TV, switch off power, remove plug and wait for 48 hours and retry.
If problem persists, I suggest it is better to refer it to a qualified service technician, since the back cover has to be opened for investigation/rectification.

Power light lights up but no picture or sound


Try changing the input device to something you are sure, works such as a DVD player. Look for any loose contacts in RC jacks/sockets/Cable.

Check your power outlet for any loose contacts.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

Power light blinks , no picture or sound , just the speakers pulsating.making a heartbeat sound.


Sounds like the TV needs some type of serivice. But just to cover your bases try unplunging it from the power from the wall and let it rest for about 5 minutes. Then plug it back in to the power and try to turn it on using the power button on TV rather then the remote. See if that works. If it doesnt call JVC.

No Picture / No Sound


What was happening before can put you close to what when out. If you had color problems or sound, or even picture going small. these are symptoms that causes the set to go out. If color look in the convergence area and look for blown fuses and bad resistors. If just went out the look at horizontal output transistor.
