Won't turn on power cord good - Protron PLTV3250 32 in. LCD Television

Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?

There are three possible reasons why it's acting like that.

1. Defective AC Adapter or Power cord
2. Defective Motherboard
3. Defective Battery

First off, you need to isolate the part which causing the issue. Please follow the following steps:

1. Remove the battery and use the power cord alone in powering up your computer. If it goes well, then you need to replace the battery. If no go, then try using a different known good outlet.

2. Check the acer power adapter (the box) if there's a light lit. If it's green, then it's should be working fine. If it's amber or nothing at all, then there's a problem with it. You might need to replace that.

3. If the AC adapter looks good, then try to wiggle the cord so that you can check if the cord is properly connected to the computer. Usually, cords get loose and it causes problems. If it has this kind of problem, then you need to get a technician to check that for you because you might need to buy a new motherboard for that.

Please do the above simple steps, and let me know if anything happens. I hope this can solve the issue.

Are there any lights or indications on the battery itself that might tell you if the battery is good? I had a laptop with a similar problem and it turned out to be both a bad battery and a bad "power brick". replacing both fixed my issues. Also, try holding the power cable at the point where it connects to the laptop and push to the left or right. A friend's laptop would only start if you held the power cable to the left. Otherwise, it sounds like a mother board issue. Sorry.

Check your power supply cord or your power socket. If they are OK maybe there is electrical problem in your printer.
Good luck.

The battery might be dead. Batteries only have a useful life and after that they have to be replaced.

Does your laptop work ok off the AC Adapter Power Cord? If so, your battery is dead and your power cord is good. If the laptop does not work off the Power Cord then either your Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. In either case a good battery will not charge if the power cord or the DC Jack is bad.

Check your DC Power Jack which is where the power cord plugs into the compute. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

You need the power cord which has a polarized plug on one end. The other end (a figure 8 like shape) will fit into the printer. See http://gdlp01.c-wss.com/gds/7/0900005347/01/ip1600esi_us.pdf . Amazon and other sites have replacement power cords for Canon inkjets and inkjet multifunction printers. One source: http://www.amazon.com/Canon-ip1600-ip6600d-ip6700d-Printer/dp/B003XT2LKC .

I hope this helps.

total dead usually means the fuse---unplug the set for safety and remove back cover---follow power cord just inside and you will find the fuse in a snap in holder--check to see if bad.............if good let me know and I will try to assist you.

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

Try to unplug the power adapter from the printer. Unplug the power cord from the power outlet in the wall. Replug the power cord after at least 10 seconds - bypass any power surge devices or power strips. Replug the power adapter into the printer. Your printer should automatically power on, otherwise, press the power button. If the printer still won't power on, please contact Lexmark technical support for additional assistance.

There is only one way to find out if it is an issue with the printer or the Power cord or Power Adapter.

Normally every HP printer has 2 parts. One cord connects the Printer to an Adapter. the Adapter cord then connects to the Wall outlet.

Now that you have connected the printer to working outlet, Check after 10-15 mins if the Adapter ( black box ) is warm or cold. If the Adapter is warm and the green LED light on adapter is glowing, then it could an issue with the Cord or the Printer.

Try with another Adapter or power cord to diagnose.

For Other brand printers, there should be a power adapter ( black box ) and it should be warm when connected to wall outlet, if it is not warm then it is defective power adapter that you need to replaced. Else it is a problem with printer mechanism.
