Yes you can repair all kinds of electronic equipment especially on lcd screen repair. Why i want to bring up the word “Passion” because only passion that can help you to repair the lcd screen and power supply. Passion in you will tell you not to give up and continue to find the answers for the electronic problems. Passion in you will drive you to even a greater level of learning and understanding of lcd screen repair and troubleshooting. Passion in you that motivates you to come out with new ideas of repairing and passion in you will help to guide you on what are the next steps you should make.
If you do not have the passion for electronics especially on lcd screen repair 
, I guess you will find this article boring and immediately exit this article as fast as I sent it to you. Well, I hope you are not because I presumed you love electronics otherwise you would not read this article.
First you must know how to test and measure electronic components. There is no point for you even if you could able to identify the defective circuit in the equipment if you don’t know how to check and measure basic electronic components. Assuming you have locate that the vertical section was at fault causing one horizontal line in the display, but because you are weak in testing electronic components, voltage checking or even scope probing, your percentage of able to repair the Lcd screen and power supply would be not high.
In order to overcome this problem, you must be able to test and check electronic components accurately by doing lots of practical test and read more information about electronic components either from the repair books or from the internet. You must pass this test first before going further. Once you had grasped the techniques of accurately testing electronic components, you have won 50% of the battle.
Second, no matter what kind of electronic equipment you are repairing it will always start from “how this electronic equipment works”. If you don’t know how the equipment function or work, you will have the disadvantage and may completely can’t repair it, i mean for lcd screen repair.
Take a look at this example, if the lcd screen problem is in the horizontal section and you conclude that the problem is in the vertical section, you will lost countless of hours trying to find the faulty parts where actually the cause of the problem is in the horizontal section. In the other words, if you don’t know how electronic equipment works you will not know at where you want to begin the repair the lcd screen and power supply.
This scenario happened very common to beginners where they just started out in the repair field. In order to solve this problem, get the electronic board back home or whatever place you find convenience where you can slowly analyse the electronic circuits. Ask yourself these questions such as “why this board need to have the optoisolator in the power supply”? Is the optoisolator functions are for overvoltage or overcurrent protection and etc? What is the part number of the optoisolator? What is inside this optoisolator and how to test it to confirm whether it is good or bad? What would happen if the optoisolator developed a short circuit? Will it cause the power supply to shutdown, produce low power or even power blink?
Hope you get what I mean. By asking questions yourself, you are actually training your mind to understand more about electronics (in the above case is the optoisolator). Using this way on other parts of the circuits in the board and I’m sure one day you will definitely truly understand the electronic equipment that you are trying to repair. If you can’t find the answer to do lcd screen repair or power supply repair, refer to electronics books, electronic repair forum or just surf the internet from different search engine (we have google.com, yahoo.com, msn.com, ask.com and etc) to get the answer you want.
