Hi, Guys How are you? So today in this latest topic we will discuss on How you can do the LCD/LED TVs Inverter IC Protection Bypass. This will be a complete guide about Inverter board IC protection bypassing and removing. SO if you want to learn it please read this article till the end.
Guys, This is the very largest topic in LCD/LED TV repairing so we will follow every step one by one In this article. So lets start.
Sometimes LCD/LED TV backlight blinks and suddenly turned off. If the TV set is ready and on but the LED Backlight is not glowing. Then this issue can be solved by removing the protection of the Inverter IC.
When the LCD/LED TV suddenly goes to the Protection mode then to remove the protection, we want to do some adjustments with the Inverter IC in the inverter board. To do this you must have the theoretical and good practical knowledge about it which we are going to provide here.
Basically we cant tell you hole process in a few words becasue this is not the simple process. First of all you need to confirm, is your LCD/LED TV gone to protection? if yes then move forwanrd to remove it.
To do that you need to read the inverter IC numbe, it can be anything the collection of some Characters. SO n ow lets assume you have the IC number and now you wan tto remove the protection of this IC. Now, just scrol down and search the IC number in this post.
If you have found it then just see the complete process to remove the Protection of that particular IC.
