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 motherboard could be defective & needs to be replaced.

Hello, I have Toshiba TV Model #47L7500U. When I turn it on the TOSHIBA (red) logo comes on for a several seconds, then screen goes black. Green LED on front continually flashes green. No pic or sound


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.

When the tv plugged up the power led blinks 3 times. When the power button is pressed the tv comes on for three seconds and turns back off. What could be the problem? Could this be a convergence problem?


Do the self check when power light goes out:

ON front of set (not remote) press and hold both the Menu and Input (Device) buttons at same time for 5 seconds or longer and release both buttons.

Power light will blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know code.

Sony KV30hs420 0 Stanby Light Timer Blinks 3 times and powers TV off


Led blinking Three times means B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672. If you have electronic knowledge you may be able to fix it. Let me know if I could help you further.
Hope this helps.
