Hi... If i understand the french posts, i think the problem will happen again (unplugging a tv from wall never repaired a tv set, guaranteed!).. but if the set is 6 months old, i don't know why not to invoke the warranty!

yes its now out from service menu after it sitting long time out of wall so its complete discharge.... don't worry it will not happen again unless if you play with service menu... so keep it.
to some one don't know Hisense if its with out Wall connected over 5 hours will reset and back to last state when it was working... and this the service center will advised in first place .Comment

Hello fellow Badcappers,
I have a Surface Pro 7 that's turning on (CPU heating up, USB powered, LCD powered) stuck on a boot logo. BIOS should be correct (ME cleaned, worked in a different S7Pro), no shorts. Only thing that seems a bit weird is the pattern in which the SSD chip is heating up. Is that normal behaviour? Rest of the SSD is 10 degrees colder.
I have replacement SSDs, but it's quite a hassle to reball and install them, so I would like to avoid doing this step if possible.
Thank you! -
The tv is stuck in service mode, i have unpluged it for several times, tryed to power it separate from remote , tryed some reset method using menu button and 4725 typed twice in a row to enter or disable the service mode but it didn't work. The board has no damaged components, could it need a fresh firmware or the emmc could be dead?...

Hello to all friends of the forum and well found, here I am asking for your help and sorry for my translated English.
As per Hisense tv title LTDN50K220WSEU stuck in standby
PSU rsag.820.5687 HLL 4855WF
Main rsag 7.820.5842
I enclose the psu diagram, after the first routine checks I find myself with a regular standby voltage of 3.3v blue light on steady when the power button is pressed nothing happens, psu disassembled and bench checked ... forced ignition by sending a signal 3 , 3v on the SW and PWM2 pins the psu turns on and delivers all the voltages... -
Background:- Hisense 65H6570G stopped working and I root caused to a burnt out LED in the backlight. (For anyone interested the power light pattern when the backlight has gone is 1) two long flashes, 2) a very short third flash, then 3) back to solid red )
- I replaced all 6 of the backlight LED strips with these replacements: amazon
- The TV worked again perfectly for ~2 weeks.
- After that 2 weeks the colors became "inverted". The TV powers on and shows the boot screen in correct colors initially (aqua hisense logo on black background, pic on the left) but a few seconds after boot

Hi this is my first question here so hopefully I can stay out of the naughty corner. I have spent time looking on here for solutions and now will ask.
The TV was given to me as it stopped working. It is almost certain there was a power surge around the time it stopped. When turned on it says Hisense powered by android. Then the screen goes black then displays the next image which the colours change a bit but never goes past that. I have tried all sorts of reset etc and believe it has corrupted firmware. I have contacted Hisense Australia and they say they have no firmware available...
