Its always good for that piece of mind in the future. Please check the pictures for part numbers. Do not trial and error my parts as you see they work and pulled from a broke screen changing the knob changes the picture light from dim to bright so it functions.
If it does not work in your tv you own extra parts I sell cheap to get rid of things. Please make sure your part numbers match to the ones in the pictures. Tv looked practically new from the back to the inside. I will help and even call you if needed.
There is no return on these parts due to as you see they work and the only way a return would be is for trial and error.
