When you plug in to the aux audio jack, that cuts out the speakers automatically. There is no switch.

Try the following troubleshooting steps.Check power cord and power outlet, possible light switch problem.
Check if you TV savy check the P board if the P board is not good check the fuses on the P board.
If the P board is OK check the A board.
To check these Unplug the TV , Disconect A5 A6 and A7 on the A board and plug the TV in and see if you get a white screen if this is the case your P board should be OK.

Almost sure you have a power supply issue. Or it could be a Y sustain board which for my set is no longer available!!!

Tries tv unplug,replug it back like about an hour later for the tv to do a resetting itself back to the factory setting.Go into the tv menu go to PICTURE to go down to do a resetting to the tv Tuner signal board.Tries scanning for channels again.The tv should be work again,if it still have the same result.The tv main board,the tv Tuner signal board is bad.Can u do some mechanicals work like take things aparts and putting it back together again?Yes?Try website like Ebay.com to buy a whole refurbish tv Tuner signal board for the replacement.

have you tried switching the imput settings

Sounds like a power supply problem. The blinking light is never a good sign. Is it still under warranty?

Yes, the unit has a problem. I work for Panasonic in New Zealand and the unit needs to go in for servicing. 10 flashing lights means a fault has occurred (if I was at work I could tell you what 10 flashing lights means).it should be repairable.

it could be as simple as the tv feeding back on itself in a dark room.
it is adjusting the light level because of what it sees ambient in the room.
turn on a light near the tv and see if it stays constant now.
