Television turned itself off and won't come back on again
Please can you help. I am in Australia so I don't know if our TV set up is the same as yours. The actual product is a Panasonic Plasma TV VIERA TH-50PX70A, your list doesn't recognise this model. Anyway the problem is this.
We were watching a film on Foxtel (equivalent to SKY etc) and the TV turned itself off and could not be turned back on again. It seem to go into Standby mode. The red light on the TV near the on button flashes on and off when you push the remote control on/off button. When you turn the TV off at the main switch and then push it on again, the TV clicks like it is going to come on the light goes green, then immediately goes red and the TV doesn't do anything. No picture, No sound.
We have only had this for a couple of weeks and the manual doesn't give any idea as to what the problem could be or how to solve it.
Thank you for your help, regards Tracey.
Re: Television turned itself off and won't come back on...
Tracy it sounds like a power supply problem, not anything you have done.This day and age the new electronics are only built for min running requirement, as in the working capacity of the power supply.Not like a few years ago when things where built to last and some still do.
It has a standby mode thats why most things have a led to show you if its on or off.This only come about for some reasons and that was to keep the old Tube Type Teleivision warm so you have instant picture, if you have turned this type of teleivision off at the wall it would take a few minutes to get a lets say a stable picture.
Enough of showing my age.
But this means the the powersupply is only in sleep mode only and uses bare min, to run and when you push the power on button you have life and then your picture.
Try this if and when it comes on and stays on, then it goes off on you, turn it off from at the wall and leave it for 5-10 min and try again, if it comes alive its a heat problem in the supply and maybe a dry joint which needs to be looked at.
If it does not try turning off and on at the set not at the remote, it could be the remote section is not working properly and have the same sort of fault. If you think it could be in the set up, try your sleep mode set up, it could be turned on, so check if the TV goes off at the same time say 5 min's everytime??
If it's the first fault you will have to get it back under warranty very quickly, these are inherent problems, companies want the dollar and not so much the quaility you get....
I hope I have helped???
P.s. if its the type where you have a power lead that plugs into the set and the wall Check that too, I have fixed many of things because the moulded lead has let the pins inside them open up..
Think basic first ok!

If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.
Tries tv unplug,replug it back like about an hour later for the tv to do it resetting itself back to the factory setting,tv might work again.If not still same problems.The tv 90-95% it is the board that call the tv power supply board is having a problems.That the board where the tv power a/c cord plug into it.U have all tools and know basic electronic and also can do basic soldering works too?Yes,take the tv aparts,check the tv power supply board carefully for dying and soon to be dead capacitors components parts.These capacitors components parts are alway bulges up or puffing up onto it tops.These dying and soon to be dead capacitors components parts are bulges or puffing ups on to it tops must have to be replaced will solved ur tv power unstable and flashing red light.Or try website like Ebay.com to buy a whole new refurbish tv power supply board for the replacement.
This shouldn't happen. When the standby light is flashing there is a problem with the television and it needs servicing. It could be the main board, the power supply, or both. This is a costly repair when a television is not in warranty. Now there are times when a television has to be turned on from the power button located on the top or side of it when first being unboxed. At a time like that the remote control will not work to power on the television. I don't believe that is the problem you are experiencing.
The troubleshooting for this is to unplug the television overnight and when you plug it back in the next day wait for the standby light to start flashing. Hold down the power button on the television set itself. Wait and see if the standby light stops flashing and turns red (or a different color). Let go of the power button. Press it once more and release it once more. The television should come on.
Even if the above works you don't want to risk something really being wrong with the television and a costly repair being needed after the warranty expires.
Turn off your television. Try disconnecting all external signal sources (except the antenna or cable) from your television.Turn on the television and see if this resolves the problem. If it does then you may have a faulty cable connection to your television. Change out the cables one by one to find the bad cable and replace it. If this does not solve your problem. Turn off for a period of hours(This may allow your television set to reset itself) and test again. If you still have the same problem, Then you need to call customer service for servicing and technical advise. Call this number for service : 1-877-467-4289. Hope this helps you with your problem.
