42" Panasonic Plasma TV won't turn on after power outage/surge. How can I fix?

The first, and the most obvious thing to check would be the TV's fuse. Not all of them can be easily replaced, and in many cases it requires the opening of the back of the TV - but You may get lucky.

The question is - is the set dead-dead (won't even show a hint of life), or is it trying but just not quite making it? Are any lights on at all, like the little stand-by light?

Sometimes the power supply can get hit pretty hard with transients (when the voltage isn't stable but varies, sometimes wildly). In many cases, however, the fuse blows quickly enough, and the circuitry remains unharmed.

All in all, checking if the fuse is blown is probably an idea worth exploring. Two words of caution: ALWAYS replace the fuse with the exact same rating! A fuse is not there to protect Your equipment, as many people believe - it is there to prevent Your death, as otherwise the overstressed components could fail in spectacular ways and cause a fire. ALSO, leave the set unplugged for a good half hour BEFORE You go inside it - the part of the circuit where the fuse (or fuses - there could be more than one) will be is the power-line side, and that particular area has stabilizing capacitors that can hold a lethal charge at line voltage (230V in Eu, 110V in the US) for some time. If the fuse is NOT blown, they would be charged by Your power-line each time the set is plugged into the outlet.

Also... You mention the TV being plugged into a surge protector? These protect from overvoltage, but they can't do a damn thing about UNDER-voltage and variances that occur below their rated activation threshold (they also usually can't do a damn thing about over-current conditions, because even if they sport a fuse, it is most likely rated for the potential current draw of the entire strip, not just one outlet). Modern appliances (like TVs) are driven by switchmode power supplies, and the way they keep the internal voltages steady is by drawing more current when the line voltage drops. Since the set was powered on and operating at the time, the power supply could've experienced what is known as an over-current state (that's why brown-outs in particular are bad for electronic equipment). In that case, some component in there might've gone on to the better plains, but only a technician can diagnose that.

You aren't exactly clear about the outlet and the surge protector. You say the outlet still works - the outlet that the surge protector is plugged into or the outlets on the surge protector itself?

Some surge protectors have a overload breaker and it is possible that the power outage caused the surge protector to trip. If tripped all you need to do is reset the breaker. Surge protectors are also designed to absorb damaging voltages before they reach sensitive equipment. This can cause the surge protector to sacrifice itself (burn out) so that your TV won't. If that is the case then you would need to buy a new surge protector.

If by chance you mean the other outlets on the surge protector work but the TV does not, I would at least try the working outlets on the surge protector just to ensure that it isn't the outlet that the TV is connected to.

If connecting the TV to a working outlet does not get your TV working then it is very possible that the power outage has caused your TV to fail. If you bought it just last August then it may be covered under warranty.

My Panasonic goes out each time there is a power outage and it has been doing it for over 3 years now. I have it on a surge protector, so when a storm comes up, I just cut the tv off. However the last time, which was this week when I cut the tv off before the power went out from the storm, I tried to turn it back on and it would not come back on even after I had cut if off. It did, however, come back on 3 days later. Just learning to live with it and keep a good old dependable tv in my bedroom to watch when this happens, but I will never buy another Panasonic either. I am 65, and seldom curse, but this makes me say a few choice words especially when my favorite place to watch tv is in the den where the Panasonic is.

My Panasonic takes a 4 day "break" for the following reasons: 1)A power outage 2) any power disruption-such as the surge protector coming unplugged 3) the TV being on overnight--it likes to be turned off regularly.

We'll get any number of blinks to no blinks . Regardless, 48 his later it works again.

Surge protectors have not helped at all.

Also, when we try to turn on the tv at the box vs remote before the 48 hrs has expired , we can feel what seems like a dangerous amount of electricity dancing around in the tv. I don't recommend touching the tv before 48hrs has expired. We leave the tv unplugged during this time.

Also, when we suspect a storm may cause a power outage, we unplug the tv in advance.

I do NOTrecommend a Panasonic--a brand 1 once liked.

Good information, that I do not believe is strictly to Panasonic.

I ve had a Panasonic 58" Plasma that the power board went out, and I have another brand, I think Insignia that recent got hit and is having issues staying on.

I also have a 42" Panasonic that "Knock on wood" I have never had problems...

After reading these and other sites, it appears that it has something to do with modern technologies versus old school power in a home.

Recently, I asked about buying a surge protector that protects equipment and trips a fuse, before tripping the home fuse. (basically I wanted to plug a stand alone heater into it, so that if it drew too much power, it would trip the strip and not the house) I m told that this doesn t exist.

This type of circuit breaker power strip would serve to protect other electronic equipment in a home. I wonder is some creative genius could drum up a marketable solution?

How many of us would pay $50-$100 for this type of Circuit Breaker Power Strip?

It looks like there are a lot of people beginning to report this problem. When I looked a couple months ago there weren't many people experiencing the same issue but it seems like things have changed now. I have this exact same issue with my TV and guess what? Mine failed about 15 months from purchase, just outside the 12 month warranty period. Obviously I'm never going to buy from Panasonic again and I've already replaced the TV. From what I'm aware of, Panasonic has discontinued Plasma TV's so I highly doubt they will replace anything or even respond to warranty queries.

My Panasonic TV is now just sitting in storage until I can find a solution. I opened the thing up a couple months ago to try and fix it but now luck. I'm not going to bother paying someone, I'll probably sell the TV as-is soon if I don't find a fix. I'm going to share some information here in the hopes we can all compile what we know and come to a solution. I have no real experience repairing electronics but I'm guessing there is a single component that is failing. My TV takes about 2 days of leaving it unplugged until it works again. Since the device will work eventually it indicates that the broken components role involves holding some king of charge and taking time to return to its normal state. I opened up the back and looked at the capacitors on the board and they all seemed healthy, I checked the inline fuse with a multimeter and it was working fine as well. That's where I gave up. Someone above mentioned that a faulty resettable fuse may be causing the issue. Maybe the fuse was tripped too many times because a component with the wrong rating was used? I'll open up the TV in the near future again and take a look. I noticed that no one has posted the serial number of their TV yet - I'll edit this later and post it since I don't have it with me. Whichever component has failed should be replaced without question by Panasonic. Good luck getting them to do that though. Anyway if anyone finds a fix or can offer advice please post here. I don't mind replacing the components myself to see if anything works. I just need to be pointed in the right direction but I'm thinking its a bad resettable fuse.

My Panasonic Plasma is a couple years old and every time we have a power outage, no matter if only a couple seconds, my TV will not start for 24-48 hours. When this initially happened I checked various on-line sites and couldn t believe what folks were saying, "It will start in a day or two", but that is so true. This only happens when the TV is on when the outage happens. I m in a rural area and the nearest Panasonic repair service is 3 hours away. I called Panasonic several times but they were no help - basically told me to make certain the outlet had power, otherwise bring it in for repair. I won t buy another Panasonic.

Panasonic Plasma Tv

My SKY decoder stalled this morning, so I switched the power off on the wall.

The SKY decoder came back on and re set itself, but my 42" Panasonic Plasma which i bought 15 months ago shows no sign of life, lights etc...

I hope it'll fix itself like some people here said.

If not I'll ring their customer service and see what they say. Maybe get a technician over to have a look.

If no one can help=Never buy Panasonic again, as simple as that.

I have just had mine go out after a short power outage last night. This is the third time in about 3 months we have had a power outage (no storm) and everything else works fine - including the 46" Panasonic Plasma I have upstairs.

The repairman replaced the control panel the first time and it worked fine - until the next outage. He ordered another panel and came out and replaced it again (he gave me a warranty on the part so no charge). Now it's out again. He's going to come out again tomorrow - but now I'm not sure it's worth fixing if it's going to just keep doing this.
