You need a live input source to the port that the TV is set to, or turn on the tv and switch input to a live input source, anything else and the tv shifts to standby.

The TV switches it self off


Sorry to here about your TV problems but it is almost imposable to help someone with technical problems if they don't list a product, model or P/N number.
Either-way, I would try moving the unit in an area where it has more breathing space if poss-able.
Also, is the unit in a air conditioned area or in a Damp basement or Florida room ?
I would also, go on line and see if Panasonic has any call backs on this unit.
This may be a feature which can be reset without to much trouble.
Next time please list the size & model #.

We have a Hitachi C28W1TN, which is just under 10 years old that has recently started switching itself off. It goes onto standby by itself and when we switch it back on, it instantly does it again. At...


It's been a while since this post, but I may have had a similar problem with my Hitachi. With no reason it would switching on and off randomly. The problem was with a solder joint on main relay - it was cracked and would not keep the coil powered so i kept flickering on/off. This relay is located on the front of pcb, between high voltage area and the switch and on my tv it is blue. Check all four joints and apply some new solder onto them. Make sure the tv is not connected to mains ;-) Hope this helps

Tv cuts off and green light flashes


If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

The flashibg red light


John, I do not know of a code, but it is a good idea in the design to have several goes at starting a circuit, before completely shutting it down. Oscillators are supposed to self start due to noise generated. Some electronic circuits require a reset pulse to be generated before the start up is allowed. The reset circuit may not be generated if the set is turned on again too soon, so it will stay in standby. This may normally be a few minutes to 30 minutes so it seems something in your set is faulty and could get worse. Try a test run with the back off and clean it out of dust with a long brush to keep it cooler. Make sure little fingers cannot get near it. Look to see if anything is obviously overheating.
