I want to find a solution, perhaps an ultimate, solution to this dilemma with your expertise. As it stands, the diffuser is too close, if not directly on the joint, there must be a way to separate without affecting image quality, I'm thinking with small glass strips or maybe pieces that make it a little distance, melan, them, or what do you suggest?

Originally posted by bohaboha View PostTHANKS diah but is it a specific SAMSUNG problem? because I see it on many other brands like Sony Philips and many other not well known brands like Voxicon etc ect... So maybe it's time to think about coming up with some kind of preventative solution
and any thinmgd u put to push the diffuser to top.. it will left shadow light on screen edge

Originally posted by bohaboha View PostThat's exactly what I want to avoid "shadow light on screen" therefore I thought of small glas pieces that you can put on the joint, it might raise some mm. Haven't tried yet but will try with a Philips that I have lying around here
about increase current sensor,. it work for HD TVs, but within 4K 8K TVs specially with HDR / HGR (10) & HDR (10)+ you will lost the color calibration value. and need to calibrate it again again which need tools. no one of us own it... just because its belong not for repair but for lab only.

Hello all .many nice advice, lower the baklight level. Or to reduce the backlight current in the power supply sure if it was my own TV and you should do from the start .but here are 8 tv s with different brands that have the same problem and the customers want me to fix them. Therefore, I turn to your experience and try to figure out something from your proposal.
Let's try again guys.

You have the answer, you are NOT going to reinvent the wheel, if the diffuser is melted it's junk and needs replaced, this video shows the upgraded diffuser. Do a search and see where you can get them, the end: https://www.youtube.com/watch?v=sawYS2pWS5k
