1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The power button could be bad.
5. The motherboard could be defective & needs to be replaced.

If the power led blinks its an error code such as 3 blinks means convergence failure which is the most common error for your model.Let me know the error code and I will assist you with what you need to do.

UNPLUG IT AND IFF YOU CAN TAKE THE BACK OFF ,,AND CAREFULLY LOOK ALL IN THERE FOR A FUSE ,,SEE IF ITS BLOWN,,

I have xfinity Comcast cable connected to my Disney's CARS TV/DVD combo. I did not have a remote for it because I bought it at yard sale without it. I used Comcast's remote control. I followed their "Searching For Your Code" instructions. #1-turn on your TV. #2-hold SET till red lite blinks twice. #3- enter 9-9-1. The red lite blinks twice. #4-press nd release the CH+ key until TV turns off. #5-once it turns off press SET key nd red lite will blink twice. #6-Now u have locked in ur code. Press power and TV should turn on. Then CH+,CH-,VOL+, and VOL- should work for ur TV.

1. Try resetting the TV by disconnecting the power for 30 seconds and then plugging it back in. If this has no
effect, try moving the TV to a different power outlet that has been tested and is known to be good.
2. If your unit continues to fail, please contact our Customer Solutions Department at 1-800-631-3811 Monday
through Friday, from 8 a.m. until 7 pm CST for a local Toshiba Authorize Service Station Hope this helps you with your problem.

It is most deffinately a convergence chip issue. The die for no reason. They can be bought online for around $10 dollars and anyone with experience with soldering can replace them pretty easily. I have done it.
