You rely on your Panasonic TV to bring you entertainment, whether it’s through a cable service or video games. Without it, the world just doesn’t make sense anymore. When your Panasonic TV won’t turn on, what do you do? Well, running around in circles certainly won’t fix it, but there’s a few solutions that can.
Take a look at the methods below and use the process of elimination until you come across one that works for you. Best case scenario your TV had a hiccup; worst case scenario you witnessed its final day.
Give It A Clean
Do a quick Google search of your problem and chances are you’ll come across plenty of individuals saying that your TV needs to be serviced. Now, they aren’t necessarily wrong, but before you start spending money, clean the TV. There may be tons of buildup back there, you know?
The reason being, any kind of dust and grime can cause a Panasonic TV—or any TV for that matter—from working. You can buy cans of compressed air at your local store for pretty cheap. Give the back of the TV a good dusting, but keep the air duster level or else you run the risk of spraying liquid.
With that said, you should also consider being really thorough. Grab a soft blanket and lay your TV across it, screen down. Obviously the TV should be unplugged at this point. Take a screwdriver and remove the back panel. Dust the inside with the air.
Check The Outlet
It’s a stretch, but have you checked the integrity of the power outlet? Try unplugging the TV and using a different power outlet. You want to rule out any possibility that it’s your home and not the TV itself. While you’re at it, give the power cable a once over. Is it connected properly?
Reset the TV
Most televisions these days come with a sort of soft reset. You can perform a soft reset with the power button. No remote required.
Here’s how it works:
1. Press and hold the Power button in. Hold it for about 30 seconds to a minute.
2. Turn the TV on.
Replace the Power Supply Board
One possible reason, though unlikely, is the power supply board went bad. If the name wasn’t obvious, it provides power to every function of your Panasonic TV. The good news is that it’s a separate piece and replacing it doesn’t require replacing every circuit board.
It goes without saying that any repairs attempted by you should be avoided if you do not possess the technical knowledge. It’s better left up to professionals. To be fair, it isn’t terribly difficult to replace the power supply board. With that said, any damage that may or may not occur while attempting to replace the power supply board is your responsibility. Techzillo is not responsible.
You will need:
- Needle-nose pliers
- Flat-head and Phillips screwdrivers
- Replacement power supply board (PSU)
- A blanket
1. Start by unplugging the TV and gently laying it across a blanket so that the screen is resting on it. Remove the screws along the outer edge to pull off the back cover.
2. When the back cover is removed, you’ll notice a circuit board in the very middle. That’s the power supply board or PSU. See the cables attached to it? Those can be removed. Press the locking tab down before removing the cables. Be gentle, but firm.
3. Examine the PSU until you find the ASSY.NO. It’s followed by a series of letters and numbers. That’s the part number, but not the full code. You’ll find the suffix part number printed nearby.
4. Visit an electronic shop or website that can order the part.
5. When the replacement PSU arrives, unscrew the damaged PSU from the chassis and replace it with the new one. Screw the new PSU board into place.
6. Reconnect cables and back cover.
Now that the PSU has been replaced, it will supply power to the rest of the TV. Unfortunately, that’s also the end of the line in terms of fixing your Panasonic TV. If the TV still won’t turn on, a professional will have to take a look at it. The likely problem is the circuit boards themselves and not the power.
