But I do not know where to find these tips. HI Fidel, Yes if all the voltages are tested good because it is not cheap and easy to find the lcd panel replacement Jestine Likes 0 Dislikes 0.
Dah check supply voltage? It will be on for a while then it shuts off. Like Us On Facebook. Also notice that Far East components are often marked without the leading ‘2S’ markresp. That means if you want to test the voltage in primary side of power supply your meter black probe has to be connected to the HOT ground. It was very informative as I am totally new to electronics. Is it possible that i can measure the output high voltage of the inverter using an analog volt meter having a capacity to measure a large amount of voltage?
August 19, This is one of the semiconductor types. The CPU can be the cause too.

Adding up, Datashee am still enjoying your very imformative E-book testing electronic components and LCD repair by: Bought your testing electronics book couple of weeks ago. Justine is not such a person, I will give the witness because I am one of the user of your system. Package form SMD Picture – number of pins. Follow my ebook at chapter 27 testing FET.
Hi Jim, I suggest that you check the surrounding components that have connection to the burnt resistors. Hi my dear jestine. Jestine Yong April 26, datasheer 8: Likes 0 Dislikes 0. Again you could see the fake one at right has some uncut plastics between the pins.
You need to check from the spec: And your book helped in providing general knowledge and good tips on how to troubleshoot a scenario. How to know these two pins exactly if there are no marking on the board? Download windows microsoft excel free. Libro matematica finanziaria pdf. It is unusual that all inverter ICs have problem.

Since this board had been repaired by someone before thus it may give a little bit problem for you. You can use voltage testing to pinpoint which section have problem for example checking the supply voltage to power IC and the output datasheer from the SMPS.
We will endeavor to search this type and inform datashret in the ECA forum. We all know today the notebook repair is the best in terms of its repair fee, but only a few of us doing this kind of repair. One of the Monitors Power Supply is very damaged because two of the was burned and one of the Mosfet also. Datadheet mystery I found was this, when the idle value is changed to These manufacturers made us repairer have headache by coming out with those funny part number.
If the value change then you know that either that component or the corresponding component have datasbeet. Whishing you and your family fro But lately i have had little success. HI Lazarus, Make sure there is power to the fan.
ST Microelectronics, Part Family: If all testes good then suspect Gm IC have problem.
Thank you in advance, Regards, Damian Dubrocq.
