Failure of Capacitor In NEC TOKIN M200 Toshiba Laptop

The complaint of the Toshiba M200 Laptop was no display with power lights on. Normal procedure to diagnose this kind of problem is to check on the cables, LCD panel and etc.  Sometimes you could locate loose connection in the cables and sometimes the motherboard was the cause of the problem.

A bad NEC Tokin capacitor sometimes will not show any physical damage-please beware of this. Since the NEC Tokin was faulty, one has to remove and replace it and this part is available from China for the cost of about USD1.30. Just in case if you could not get this part, don’t be despair because you could use a 330uf capacitor as replacement. Another way is to put the 330uf capacitor at the Processor socket slot (use this method for M200 Model only).

It is not easy to remove the capacitor. You need to use hot air to blow on the top and you also need a heater station to place it at the bottom. Set the temperature to 200 Celcius for the top hot air and 200 Celcius on the bottom and the capacitor will be easily removed. Make sure to cover the surrounding components with aluminum foils otherwise the components will get burn.

If you did not use the heater at the bottom and only blowing the hot air on top, the possibility of the NED Tokin capacitor will be damaged. Soldering back the capacitor will be another problem because the solder will not stick on the base of the motherboard. In order to solve the problem you need to use a small wire cut off from the capacitor or resistors leads. By using the hot air and the heater at the bottom, it will be easier to soldered it back.

After I have done with the replacement of the capacitor, the display came back upon turning on the power. This is a simple repair and it only cost about USD1.30 to solve the no display problem in the Toshiba M200 Laptop.

I am 17years ++ going to 18 start repairs while in Form 1 now 5 years in repairing. I repair PC related hard wares like motherboard LCD and CRT monitors TV and recently Laptops. I learn it from Professional repairers and also from Jestine by his E-Books. Though still learning, my willingness is to have fellowship with fellow repairers for more knowledge and experience. No one will claim he is perfected haha. Hope to gain more experience and to make more friends in the repair field .

    I just happened to see this useful post today. I have recently replaced NEC/TOKIN OE128 capacitor in my Toshiba A200 laptop without using any hot air gun and it is working perfectly now. I have provided a number of useful links, photographs, etc here:
