It looks like the power supply failed on your TV.
You might be able to find a power supply for your TV for around $125.00 plus shipping and handling.

Tv has sound but no picture


This is almost certainly a problem with the backlight power supply, not the ac adapter. If the backlight isn't working, you will see nothing on the screen.

Dell Inspiron 1521 battery not charging


Laptop batteries power a laptop when it is not connected to an electrical outlet. If the laptop battery fails to charge when the laptop is plugged into an electrical outlet, the battery is likely dead and needs to be replaced. Unfortunately there is no way to fix a dead battery. However, while a dead battery is the likely cause, it is not the only cause. The AC adapter may be broken, in which case the battery won't charge, or the battery contacts may be dirty and need cleaning. Prior to replacing the battery, perform simple tasks to ensure a dead battery is the cause of the problems.

1.Power down the laptop. Gently pull the AC adapter from the side of the laptop for removal.

2.Place the laptop in front of you, bottom side up. Locate the battery release mechanism. This can be a button that slides or needs to be pushed to unlock or release the laptop battery from the housing unit. Press or slide the mechanism. Slide or lift the battery from the battery bay for removal.

3.Insert the AC adapter into the side of the laptop. Power on the laptop. If the laptop does not power on, ensure the AC adapter is securely plugged into a working electrical outlet. If the electrical outlet is working and the laptop won't power on, the AC adapter is not properly working and needs to be replaced. Remove the AC adapter.

4.Dip a cotton swab in a small amount of rubbing alcohol. The cotton swab should be damp, not dripping wet. Lightly rub the dampened cotton swab onto the battery contacts and battery bay contacts to remove dust, buildup and grime. Allow the contacts to air dry.

5.Align the battery over the battery bay. Either press or slide into place. A clicking or snapping noise produced from the locking mechanism will confirm the laptop battery is securely locked into place.

6.Install the AC adapter. Allow the AC adapter to fully charge the battery for 8 hours.

7.Remove the AC adapter. Power on the laptop. If the laptop does not power on, the battery needs to be replaced.

I have a Protron TV that went dead. Although it


Are you getting the 12vdc and the 24vdc from the power supply?
Since your TV uses AC ADAPTER type power supply, you need to check and see if you do have 5vdc (5vdc is converted from the 12vdc power) for the processor.

if the pc is not getting power without the ac adapter then most likely the battery is dead if it does not take a charge via the ac adapter then then the battery is no good or the ac adapter is busted

Unable to start the computer. power button will light up for a second but no fans or other noises and then the light goes off


i would say try replacing the battery or the ac adapter. I had the same exact problem on my toshiba a105-s171. my battery was dead because the ac adapter failed to charge. Replaced the adapter and it works now.

The laptop just went dead. Does not power up off


check the pins on the adaptor connector that goes into the laptop socket....
they all must align correctly....
normaly it will have three pins, even if one is bent or mis-aligned it will not work....use a small screwdriver to slighly adjust the pins to the aprox correct postion...use a mignifying glass to have a look into the pins....

Dead Sony Laptop


If power supply is supplying correct voltage, then you do not need power supply PCB.

Try starting the laptop with AC adapter and no battery, if battery is shorting out you may get same problem.

Test the soldering joint on the AC socket and laptop motherboard, if there is a bad soldering on laprop ac adapter socket, you get same symptoms.

If it is none of the above, and the adapter is fine, then it is usually a faulty motherboard.

TV seems to be dead


Yes with an LCD it can be dead. The life of LCD is not nearly that of a tube TV. It depends on the hours of use. Most likely time to replace it.
Good luck,
