dig up yr purchase papers, make report to sharp service to start warranty case.

i see green line instead of yellow

Oh wow! 
Changing the screen is very big fault.
I would have thought only need to change the motherboard

I cannot use Netflix on my LC-50UA6800X because it demands the Android Software to be updated. But whenever I try to update the TV via OTA, it says "cannot access the network". Also tried to google if I can download the software manually and put it in a flashdrive, but I cannot also find anything.

Does somebody here experienced the "cannot access the network" thingy?

Is there a remote control app (Android/Apple) available for the UA6800X ? There's a Sharp app but can't use it, both Android and Apple.

Yea,
technician didnt show much interest to check deeply.
I google that this kind of failure is mostly "TAB error" or losing connection on ribbon cable to screen (a simple re-seating of the cables usually helps).
As is under warranty.let them to change panel.

What's this upgrade all about?

may i know the ATV version for SHARP LC45UA6800X?

is it android 7.0? upgradable to 8.0?

Update my case
Sharp technician bring Blu-ray player come to test
And still the same after few settings

Noticed nothing changed but security patch update.

Is this model 60ua6800 a  good value for money tv or topup rm1000 for Panasonic x740 65inch?

All Sharp UA6800X owners, not sure whether you faced the same issue like mine. I just bought a new 60UA6800X from Harvey last week @ RM2880 (5 Years Warranty). Not sure whether it is a good deal but it's below my budget of <RM3K. They do have 60UA6500X @ RM2500 but some of the missing features make switched last minute (no ATV, less HDMI port, no ARC, panel color gamut lower). Initially wanna go for Samsung Q60R 65" at RM5500 (5 Years) but have to let go due to much higher price.
When I test HDR color capability of the TV using 4K HDR videos from Youtube, the color stat always show bt709 (below). By right if the video support HDR, it should be bt2020. Anyone face the same issue like mine on their UA6800X ATV? I have updated my ATV to latest and UNiFi speed at 50Mbps.
Technically I think this model support HDR. I dont think it support HDR10 though, after all it is a 1.5 year old model. Nevertheless, the quality is way better than the LG 55" UB850T TV it replaced. The LG smartly went kaput right after the 5 year warranty ended and the quoted repair cost by authorised LG service center was so expensive.. will never never buy a LG TV again. Sumore, it was so expensive last time @RM5K.

Any ideas? Do you all face the same issue when running HDR content from Youtube? Thanks

Woke up this morning saw this kind of vertical line across the screen. This month will be 2 years for my sharp. Is it possible to claim warranty? Bought extra warranty from senheng.
