Hi all.
I've looked on xda and the Internet for the last few weeks but haven't been able to find anything to help.
About six weeks ago the problems started I think after an update to the o/'s.
To turn the tablet on I have to hold the power button on then the battery symbol is shown if at this point I push the home button then the battery symbol shows its charging even though it's not got ant USB plugged in. Then I have to hold the poem button again to turn it off then holding the power button in for a 3rd time the tablet boots up into android and I'm able to use it. When the tablet is on with nothing plugged into the USB port if I push the home button the tablet beeps and then shows the charge symbol. Push the home button again and it removes the charge symbol.
When a cable is plugged in charging then I get a red cross over the battery symbol when I push the home button. Push the home button again and the red cross disappears.
The only info I can find says change the internal USB ribbon and/or the battery. Which I've done both and still the same.
I was thinking of reinstalling the original rom but I cannot get it to fire up in the correct mode as it won't recognise the volume button on start up.
Any help would be great. Thanks
USB port may be faulty or loose I reckon
HI, after a full charge, i unplugged my ze551ml, it showed up lockscreen and everything seemed ok.. after natural automatic screen lock it never went on.
Black screen and no signs of activity at all, neither vibration or sound.
tried to long press power button => no response
attached to pc => no fastboot / adb
tried combining power/up power/down power/up&down buttons without success
no update where made but yesterday it showed MM update notification which wasn't accepted.
is there any chance to make it live again before doing RMA?
Just to check
Press and keep pressed Vol+ and power for 3 mins, then connect usb lead to phone -- dont have it connected to charger or any device, then release button then try power on,
just a test to see if your usb port is at fault - try a combination with cable in and out
Hi!
The TV was not mine to begin with so I don't know how it got in this mode, but i suspect that the last owner was fiddeling with the service mode settings(I bought it as defect by an insurance company)
So. As soon as i plug in the TV it loops the colors Black, White, Red, Blue, Green. No response to any buttons on remote/TV, ONLY the powerbutton. But that rarely. I need to press the powerbutton many times so it responds.
I tried many key combinations, Input + power, menu + OK etc etc. I tried spamming everything, no response.
I wanted to try to get the TV to reflash android software by plugging in USB with android 8.0 and pressing power while plugging in, but no response, the USB led lights up on the usb stick but the TV doesnt show if it's reflashing or not. it just loops the colors.
I tried leave it on, maybe the test ends by itself and goes to normal, but after 15-20 minutes the TV turns of by itself. no help
Any idea on what I can do? can I factory reset it in another way?
How much did you pay for it?
Hello everyone,
I thought I was technically sufficient, being an engineer, but apparently I only know about physics and the world of electronics is lost on me.
so my tv, a philips 55PUS8700 was not starting up correctly and in a frenzy of utter frustration I smashed some keus on the remote.
Now it’s in a loop, flashing alternating colours green red and blue and bright and dimmed white which I read is a colour test mode. Now I also read it should do this once, however, it’s a never ending loop that I cannot get out off. Tried the obvious things like powering off, waiting, various key combinations but the set is not responding as I would like. Is this a problem perhaps with the eprom (don’t laugh at me, I’ve been reading various dubious sources), or something else?
Hi,
try to access the recovery mode ...
- pull power cord
- press cursor on the back of your TV down and hold it down
- while pressing down, reconnect power cord
- still hold it for at least 5 sec
- recovery should start

Thanks for the reply, but unfortunately I had already tried this several times to no avail.
Hello
I think i f#cked up and gain an new dart target.
So, i had an eletric problem that shuts down the power a few times.
Betwin the power shuts the tv was on.
After the tv starts to behave like this:
Turn on, show tcl logo, and goes screen off (back light on), when i touch any button (remote or local) it show the gear with the red cross and reboot.
Other times same behaviour, but before goes black it shows the android loading animation.
So i thinked, ok something went wrong, i grabbed an pkg file (at this time i dnt know which one) put it on a pen, on port usb 2.0, and rebboot tv holding power button... Its show update bar.
After a while screen went black, waited 30min, nothing... So i did a reset, removing power.
Since them when i power on, the white led goes on, and nothing more.
Tried power cycle.
Tried power cycle holding power button while off grid, while pluging it in etc.
Tried a bunch of diferent img zip pkg files, and nothing.
I suspect it will be necessary to jtag the SoC... Hope no...
So two point
1) where to find an main board to buy on europe, in case i need a new one... And part number if anyone has open is tv.
2) is there anything i can do at this moment? Recovery? Etc
Thanks you all
Hello,
