So it’s hardly just been two or three years for your LCD screen to serve you with all the entertainment and one fine day, what you see is, you have a big dent in the screen, probably due to some obvious reasons or perhaps some internal technical reasons. Whatever be the reason, the bottom line is- you have a broken LCD TV screen and you are on a high to either learn to fix it or replace it entirely. The broken LCD screen problems can not only arouse in television sets but laptops are also prone to such issues. Many people have this tendency of repairing a particular piece of electronic item rather than going for its overall replacement. While many others believe that if the repairing cost is tossing out to be more than the cost of the whole replacement set, it’s better to purchase a brand new LCD screen and fix it to the old unit. Well, this thought isn’t bad either! But there are two most important points one has to look out while going for the replacement procedure and they are: firstly, see that the screen hasn’t extended its warranty period. And secondly, the consumer needs to find a reliable seller or manufacture if he/she wants to buy the LCD screen in a good price. Later on, they might also have to find reliable service men who can fix the new screen and do the overall job correctly. The cost carried for the same is different. So, although replacement sounds like a good option, it is bit lengthy and fallible. It is advisable that one should go for the broken LCD screen replacement procedure only when there are a chain of problems in the whole working unit and not just one or two.

Step #3: Also what else you would see is an inverter board mounted at the side end of the motherboard. Remove all the inverter screws and expose the whole unit. There will be a bunch of cables connected to various ports. They transmit electrical power to the LCD screen.
Step #4: Your first job to do is, check for all the connections of the inverter board to see whether they are properly secured or not. If they aren’t, unplug the cables and try plugging them back into the ports. Power the screen and see if its working, if not, then go ahead.
Step #5: Remove all the fasteners, plugs and connections from the ports in the board and pull out the whole board from the TV set and keep it aside.
Step #6: Now replace the old for a new board. Fit the new replacement board in the television, and hopefully you have marked the positions of the cable connections. Join the cables together and attach all the screws back in place. Lastly, replace the back cover of the inverter and also the rear panel of the television carefully.
