[4 Fixes] Sylvania TV Won’t Power On (100% Working)

If your Sylvania TV doesn’t power on, get issues like having a faulty power cord out of the way first. That leaves us more precise reasons, such as a bad audio/video connection or improper coaxial connection. Solving either of these is no big deal at all, as you only have to reconnect cables in the correct manner.

However, you might be dealing with more technical faults like a blown-out fuse or a faulty capacitor. The solution to such problems requires an intermediate level of expertise in tasks like dismantling the TV and soldering. If you are uncomfortable with such things, a visit to the repair shop would be highly recommended.

Is There a Reset Button on a Sylvania TV?

Unfortunately, most Sylvania TVs don’t usually have a dedicated reset button. However, you can use the power button on the TV to get the job done. Simply press and hold the power button for as long as 10 seconds to reset the TV.

The above trick should work for most Sylvania TVs regardless of their model. But don’t worry if it doesn’t, as it is pretty usual after a power outage. An alternative way can be the self-reset mechanism found in many models.

For this method to work, switch the unit off and unplug the power cord from the electric outlet. Then, wait for about 30 minutes or so. Meanwhile, the TV will reset itself before you plug the power cord back.

How to Fix the ‘Sylvania TV Won’t Power On’ Issue?

First of all, you have to accept that electronic devices often fail, and more often, they can get fixed. That said, you’ll need to go through a few troubleshooting steps before deciding whether or not to seek professional help.

1. Faulty Audio/Video Cable Connection

The first step is to check the audio/video cables connecting your Sylvania TV to the satellite or cable receiver. Generally, a multi-colored cable having three prongs on either end establishes the connection from the receiver box.

Each color must match its respective connecting points, which are also multi-colored. And if there is a mismatch, like a white cable going into a red port, it will prevent your TV from powering on. If you find such an issue, try reorganizing the prongs according to their colors.

2. Loose Coaxial Cable

You should be able to notice the coaxial cable on the rear side of the receiver, attached to a port labeled as ANT IN. Once found, check if the connection is a firm one. Generally, a loose coaxial connection results in the display appearing static.

The solution is to tighten the cable. You can do so by pinching the silver band on the end of it and rotating it clockwise. Keep twisting to the point where no more adjustments are possible.

3. Interference

If the distortion continues appearing on the TV screen, it may be due to some interference nearby. Generally, power-hungry appliances cause electronic interference, which in turn gives birth to display irregularities. So, keep your computers, speakers, and stuff like those at a distance.

4. Blown Fuse

There is a fuse close to the connection between the circuit board and the power cord. We recommend opening up the TV to get a closer look if you’re used to technical stuff like that. Once you have the TV open, check if the fuse got blown. If so, replace it with a new one having the same rating as on the metal part of the fuse.

Bonus Tips: How Do I Get My Sylvania TV to Work?

The above troubleshooting section tells pretty much how to deal with what in terms of malfunctioning Sylvania TVs. Nevertheless, if you’ve tried all methods but in vain, here’s a more general approach.

• Switch off the TV.
• Unplug the power cord from the outlet.

• Press and hold the power button for at least half a minute.
• Release the button and plug the power cord back in place.

Now, try to turn on the TV to see if that helped. If not, you might be dealing with a faulty power adapter or a damaged picture tube if yours is an older unit. In the latter case, there’s no other way than to contact a professional. But as for the flawed adapter, you can get a replacement in the after-market.

Wrapping Up

Chances are, the built-in protection mode is kicking in each time you try to turn on your Sylvania TV. It is basically the device turning off automatically as it fails to power up the screen. Sometimes, a bad inverter transformer causes this issue though the culprit is the power supply being unstable due to bad DC filter caps.
