To fix LCD screen power adapter is simpler than the CRT monitor power supply. It really is tiny and also compact and generally has only one outcome that is 12 volt and even varies from 2 ampere to above 4 ampere. Quite a few created have 18 and 24 volts additionally. Currently a lot of LCD power supplies are usually develop to the major board like the HP Pavilion G60 LCD Screen as the elderly kind were definitely separated as electrical power pack module.The energy pack module type is easy to help detect since you cancan easily take the place of another working unit simply to ensure could be the electrical power pack which giving issue. You might also make use of the external dc power supply to help switch on the LCD to verify if your power pack is defective. If you dont possess the exterior DC power supply, you are able to usually take this solution to isolate the problem particularly the signs are usually no power, low energy as well as power blink. While using rear light bulb (12 volt) from the car and also connect this towards the power pack output jack. In cases it light brilliantly then a power pack is actually right. If this blink or even dim the power pack currently have problem. Exactly why need to make use of this method to test it? Simply because if there are elements shorted or leaky in the LCD principal board, it would affect the overall performance of power supply.From experienced, almost all LCD power issues whether in the power pack or even constructed into main board were because of the failing of electrolytic capacitors (most likely caused by heat) within the major and also secondary part. Lots of the capacitors have a very big ESR that causes the power supply to provide low output, blink or absolutely no power at all. Typical value electrolytic capacitors within the major side are usually 47 and 100 micro farad 50 Volt and also the secondary aspects are usually 1000 to 2200 micro farad 25 volt. Occasionally you will notice the capacitor best casing grew to become bulge and also the sleeve which covered the capacitor casing converted into darker color just like brown.The power section in most of this LCD screen continue using the UC3842 pulse width modulation (pwm) ic. This kind of ic is pretty easy to find available in the market compare to some power ic that is really hard to get. lp133wx1-tlb1 screen is actually using the TOP247F electrical power ic which is certainly rather easy to troubleshoot in case electrical power fail in such a model. Quite a few electrical power pack which usually came in only get minor burnt and also right after cleaning this and also replaced the fuse, itll work as great as the brand new one.Troubleshooting LCD power adapter isnt that hard given once you learn how a power adapter performs. In case you are not sure of how to troubleshoot power adapter, I want you to definitely study all my own power adapter articles at the power supply page. I am going to continue to submit much more power adapter posts and also wish you can drop by more regularly to look into my website.
