We lost power, (not a storm) and when power was restored tv would not turn on. We checked the outlet and the fuse. Is there anything else I could try before taking it somewhere for repair? This tv is only 2 years old.....I'm hoping it's not a loss. It was working perfectly fine before we lost power. It was not on when we lost power. Help?
Last night, my Panasonic television went off due to a partial electrical power outage that affected my house.After the power was restored, the TV would not come on.The electrical outlet being used is good.I was looking at the parts list for the TV at Panasonic website and saw a fuse (6.3A-125V) listed.Maybe an electrical surge last night burnt this internal fuse out and that is the only thing I will need to replace. I wonder if this was the fuse that Leen14 was referring to in the original post that checked out good.Any additional information will be greatly appreciated!

Did this unit fail after a power outage or passing storm? If so could be lost of component in the low voltage power supply circuit or degausing relay circuit. I would strongly suggest you seek help from a qualified repair center. Don not attempt to repair yourself...to dangerous.
First, make sure the outlet where the TV's plugged in is working. Unfortunately, a set that's dead after a power failure (especially if it was storm-related) isn't something easy to diagnose without looking at it in person. It might be something as simple as a blown fuse. But the damage is frequently more extensive. Without electronic servicing skills, the proper test equipment and a circuit diagram of the set, there's nothing you'll be able to do to repair this on your own. If you want to keep this set, the best thing you can do is find a servicer in your area who can check it over and make an estimate for the repair. For a small TV, you may find it more economical just to replace it.
next time dont leave your tv pluged on power, the power supply got burnt, check your power supply on the following components
fuse, power transistor, zener diodes,also rectifier diodes
if you can manage do it at home
or take it to a w/shop
Pull the back Off Disconnect CRT board connected at End of picture tube then turn set on and see if it comes on with volume, high voltage you can feel front of tv for static elect.... Let me know what happens then i can tell you what is wrong with TV.
A: Is there a humming sound coming from the TV set? Check the brightness/contrast. If nothing still, remove power to the set for 24 hrs. and reconnect and retry. If it's not coming back up, the PCB ("motherboard") for the set has most likely died. Check for warranty information in your user's manual for further instructions.
B: Is the TV sharing an electrical line with a wall switch? Remove the set from that circuit and try another outlet. If not, follow the Steps for "A".
C: Was it during a power storm, when it went blank? Check the outlet with another appliance - if that device works, try the Steps in "A".
