It could be. But make sure the power outlet is ok. Please try on a different power outlet.

SOURCE: TV won't go off of

You might wish to unplug the TV for an hour or more. If this power reset does not allow the TV to turn on component failure is indicated. These sets are assembled using the wave soldering process they are known for having cold solder connections.

The safety circuitry shuts the TV set down or will keep it from turning on when it detects a problem. This model of TV has over 2,000 parts, which includes millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Diodes and IC can go bad.

This may have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again if the parts that caused the failure to begin with are not replaced.

The only way to know for sure which parts that are no longer within factory specs and for a proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment specifically designed for TV service and the skills to use the test equipment. I wish I could tell you there was a quick fix or button to push that would fix the TV but that is not the case or the solution needed to get the TV operating correctly.

It's the problem of overheating in the power supply board of the TV.on the power supply board of the TV there are few capacitors and IC.any of this IC is got short or may be weak.so due to this when you start the TV the current passes from electric outlet to the power supply board of TV.but when the current passes from that weak/faulty part at that time current gets stopped or slow and the board overheats and TV shuts off.

This is a common problem faced by many other users too.the possible option to solve this issue is to check the power supply board by a meter and continuity tester and replace the faulty component on the board which is short due to which power supply board is getting overheated.its bit technical job but yes its not at all a costly repair to do or get it done by the technician. for required parts it can be easily available from local electronic hardware shop.

Hope this will help in solving the problem.......

If the standby light is on and it does not respond, it is most likely to be a problem with the power supply . First try this, unplug and leave the set like that for a few hours. Then plug it back in to see if the tv attempts to turn on when you try to power it up. See if you hear a "click" even if it goes back to standby. Let me know what you found so that I can help you test the power supply board to confirm, if necessary.

I have an acer aspire 5100 and here recently the


Could be a bad battery and/or charger/AC Adaptor/DC Connector. Try to isolate the problem by removing the battery and then plugging the laptop charger in and starting the pc up. It should boot on the AC adapter alone. If it won't boot on the AC adaptor or it flickers and flashes while on the AC adaptor, I would first suspect the AC adaptor or the DC connector on the laptop (try wiggling the power plug at the PC to try and check the connector). If it behaves while on the AC adaptor without the battery present, I would suspect the battery. Either way, you may have to replace something.

My remote speaker system works with the batteries but not with the AC adaptor plugged in to the speaker.


I would suggest to check AC outlet first where adaptor is pluged in,if Ok measure output voltage from adaptor to see if there is any (using any voltage multimeter with AC/DC)
Check label on adaptor shold be writen AC or DC output ,and value 3V,6,9,12,24,48 etc...
If adaptor is ok then problem is power jack mounted in to the speaker (cold solder joints' or damage)

I have a HP dv7 laptop it does not work with the ac adapter but worked with the battery, whenever it is working with the battery and the ac adapter is connected it shuts down.


Remove the battery and plug the ac adaptor in check wethere the light on the port where you connect the ac adaptor glows or not, if no then check the wethere the ac adaptor is getting warm or not after you plug it in for few minutes if not then ac adaptor has to be replaced.
If the light on the port is glowing then it is likely that the power supply of the notebook has gone bad as it is not able to switch to ac adaptor or the port where you connect the ac adaptor to the notebook has a short circut when the acadaptor pin is connected , better try with a different ac adaptor to be sure wethere the issue is with ac adaptor or the notebook.
My best wishes

I have a Dell D600 (PP05L), its not powering up no lights. I noticed on the power adapter the green light goes out when plugged into ac power. What could be wrong here? please help


Hook up your power adaptor to ac power without it being hooked up to the laptop and see if the green light stays on. If it does then you know your adaptor is okay. if your adaptor is only hooked up to ac power and the green light still turns off then you know your ac adaptor is bad.

Take out the battery from your laptop. Now hook up the ac adaptor to the laptop and if it stays green then you know your battery is bad but you also want to make sure you can get your laptop to turn on. Hopefully it will turn on with only the ac adaptor hooked up to it.

I bought a targus ac adapter, it worked the first time I charged my Dell 5100 Notebook computor, now a message comes up saying it doesn't recognize the ac adaptor, how can I fix this?


AC adaptor may not be correct. Check label on AC adaptor with label on notebook for voltage (e.g. 19.5V or 20V) and current (e.g. ??A or 90W)

Voltage must be same and current must be same or higher on ac adaptor.

Lightning strike ac adaptor is fried


Your phone did expirence a surge that probably blew the ac adaptor which happens most of the time, u can buy one of those universal adaptors and look on the back of the old adaptor for the output voltage it will usually read between 3 and 8 volts DC.Set the universal adAptor voltage to the setting right below the voltage output on the back of the ac adaptor.

Lap top problem


Hi

If the AC power light is blinking, try the following steps:

1 Cut off power to the computer by disconnecting the AC adaptor and removing the battery. The error condition will be interrupted, and the AC power light will stop flashing.

2 Put the battery back into the computer. Do not connect the AC adaptor. Try turning the computer on again. If the computer starts normally, the AC adaptor may be
defective and will need to be replaced. If the AC power light starts flashing, remove the battery, and continue with the steps below.

3 Connect the AC adaptor to the computer. Leave the battery out of the computer. Try turning the computer on again. If the computer starts normally, the battery may need charging, may be depleted, or may be defective. Turn the computer on, insert the battery, and then leave the computer running for several hours, which will deliver a slow, steady “trickle-charge” to the battery. Once the battery has been trickle-charged, it may begin working correctly again. If the trickle-charging does not prove effective, consider replacing the battery with a new one.

4 Connect the AC adaptor to a different power outlet, preferably in a different room. If the computer starts normally, there may be a problem with the AC outlet itself, or the voltage level available from it.

5 Verify that the AC adaptor is the correct unit for your computer model. The computer may not be able to start from an AC adaptor that is rated for less current (amperage) than the computer requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket. The labels on the bottom of the computer and the AC adaptor show the specifications for voltage ("V") and current ("A") for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the computer
