LCD replacement on Laptops and notebooks

Often it's not the costly LCD panel that is broken. It's the ten dollar inverter. So before shelling out hundreds of dollars for what you were told was an issue with the LCD replacement. Change the inverter, It's a 15 minute procedure that is easy to do as pulling out a plug and putting it back in. It is located in the frame of the lid where the LCD is housed. And can be accessed by removing the little rubber bumpers "which are normally just glued on" underneath are small screws, usually 6-8. Then the frame snaps off, it's held on by clips. Just be careful not to force too hard, but there is a lot of flex in the frame due to the need to get in there to fix many parts. Now at the bottom there is a small rectangular or pen shaped tube that has a plug on both sides. Just copy the model number and find a replacement in a local computer parts store or on Ebay, I have bought several there myself. Replace the part the same way you took it out, and you can actually reboot it once you do that without even re assembling it. There you go, you just saved $300.00. HP told me "a tech" that it was definitely my LCD, and it was off warranty for 1 day, They told me it would be about $400.00 plus shipping. Get the picture. The diagnosis without proper equipment is almost impossible. If you lost your picture or it's very very dark almost impossible to see, there is more of a 50/50 shot that it's just the inverter. Happy computing

My lenovo g 475 lcd screen was broken. How much would it cost for me to change it?


Usually screens cost a few hundred dollars to replace, because the inverter (what powers the lights that make the screen bright) has to be replaced also, adding to the cost. I would call Lenovo and see how much they will charge you. Sometimes manufacturers will do it for free, but that isn't a guarantee.

Hi, while i was watching my Sinotec TV, it just switched off by itself. For a moment i thought it was the power that tripped but i was wrong. I tried to plug it on different endpoints but still not switching on. suspect a power supply on the TV is blown.


Yes, Look up your TV Model Number, then youtube assembly and disassembly instructions to replace LCD Inverter and/or Power inverter.
On Flat panel televisions its usually a standard power inverter, sometimes smaller LCD inverters though.
a relatively cheap replacement part and a job you could do yourself to save yourself a few hundred dollars.

The LCD  is fine as you can see the display.

This is a backlight fault.

 

This may have been caused by dropping (breaking the backlight tubes) or the inverter circuit has become faulty.

 

This should not cost hundreds to repair.

 

I think you should talk to the seller with a view to getting your money back first though.
