Samsung UN55JU650DF network/streaming problem

[howardc64]

Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.

This TV runs older Tizen OS (updated to latest version, see pic) and have problems with network (wifi or ethernet) connection. The Tizen UI frequently switch to coax input source while changing content sources. . If no good signal (coax not connected, no prior antenna/cable scan (snow) or just poor antenna reception) launching streaming apps often encounter network problems (not network connected popup menu (WAS0003) despite connection properly setup and working previously, or app like youtube would be slow or freeze) If a good signal on coax (I used antenna) then streaming apps is quite robust.

This Tizen smartTV OS is slow by today's standards but still usable. But I guess Tizen has some problems dealing with no/poor signal coax input which impact other streaming apps network connection. Anyone else encounter this?

I've tried to change the Wifi Region to A (TV defaults to S) in Service menu and seems no difference. In any case, ethernet having similar problem suggesting its Tizen OS related.

googled WAS0003 error code and looks like Samsung firmware update introduced this problem ( link ). Sounds like maybe best to avoid all Samsung TV updates as they regularly mess up the firmware and can't rewind.

Indeed, have seen many times where updates took away some features of previous firmware. Guess they figured they would sabotage peoples tvs and hope the consumer didn't realize it, maybe hoping they would buy a new one from them. Shame on them.

Did a bit more testing. Seems like this older slower Tizen just require a bit of patience.

• First turn on the TV, apps menu pop up on bottom. But in reality, app system is just setting up and network getting connected. Need to wait until this menu disappears before popping it up again to launch apps. If earlier (like when it first pops up which invites user to launch the app) will get either wait for system to setup msg or the network not connected msg.
• Sometimes apps hang and unfortunately older Tizen has no "quit" app mechanism. Go back to home screen, switch to a none steaming source (I did coax air/cable, maybe HDMI would work too), wait a little, then launch app again seems to restart the app. Some people says online they pull the power cord haha.
• If antenna/cable tuner not scanned and setup, then get noisy snow screen which unfortunately usually cause user to press app launch buttons sooner.

Anyhow, slowish smart app system. So user need to be patient or wait to resolve the crashed apps. Easier to just use latest generation cheap 4K streaming sticks.
