I have an LG LED TV model 50LN5600-ui. It has no picture, does has sound and the backlight turn on for just a second. could it be the T-com or LED strips?


Hi Omar,
Most likely it is the backlight in your TV causing this problem. Please check the backlight strips if you can. T Con board has nothing to do with this fault. I hope it helps.
Good luck.

Vizio 420i-A0 Backlight issue. Screen was dark in the center. Checked the LED light strips. Only top and bottom strips were working.


It could be a defective LED strip you bought. You may swab the top & center strip to check it out.

Hitachi LE55A6R9A has sound but no picture. Passes flashlight test. No LED backlights appear visible at all. Trying to determine whether to start replacing boards or LED strips first.


The led driver may be on the main board or on it's own board. Led strips don't fail all at once so if you had a dark area of the picture then I'd suspect a led strip. TV Parts Universal TV Stands DLP Chips ShopJimmy This is the place to get parts.

I have a Samsung un46eh5000f.i replaced all boards and still can only see picture with flashlight. Should I replace led strips?


Hi,
After changing all the boards the only thing left is backlight. Please check and replace the faulty LED or the strip if you can. Opening the panel for changing the faulty LED or strip is a tricky and riski job. Please be careful.
Good luck.

Vizio Customer Service said that I have a Partial backlight failure and unrepairable. My question is how do I repair this?


Hi Chad,
Partial backlight failure in LED TVs means some of the LED bulbs in the backlight array have gone bad. It is repairable by replacing the bad strip. Some times when the strip is not available, the defective LED alone can be replaced. But, the job is risky, and delicate. There are chances of damaging the panel if you are not in practice of doing it regularly. Your set being 55" means you have to be extra careful while doing this.
Good luck.
