Hello team,
hope you are well.
I have this tcl u55c7006 for around 5years.
Sudenly it started crashing 5-20 seconds after booting up, either on TCL moving logo or android logo a bit later.
I've tried factory reset (holding power button on boot for 20secs+) or tried several images flashing without success.
The original build on this tv that shows on the board sticket is V8 t658t01 lf1v162.
I've tried also to disconnect all unecessary output from the board (button, speakers, wifi, leds, IR receiver) without any change.
Was anyone here successfull to overcome this problem?
Would a hardware store be able to resolve this problem? The tv is still ok , and the panel is ok, so i'm a bit sad throwing it to the trash :X
Thank you

I've just bought a 2nd had vega off ebay and it switches on and runs everything (including the touchscreen) however there is no display, the screen just remains black.
I know that everything else works because I connected it to my telly with HDMI and I can control my device looking at the tv (its not easy)
I've reset the tablet back to stock rom etc but still the screen remains black
Is this a duff device or does anyone know a simple way that may fix this?
Thank you in anticipation
If you also don't see Android's and Manufacturer's logo shown when booting up your tablet then I would say that it's dead and need to be returned.
If you have trouble rebooting it, press and hold power button for 9 seconds. It should be completely turned off now. Then hold the power button for 2-3 seconds in order to boot it up. Company logos should be shown now.
Hi thanks for your help. Vega now fixed. I took off the back and reseated the connector and hey presto it now works.
Glad you fixed it yourself!
It just shows that the build quality of Advent Vega and its clones is really low.
Hello evryone,
I'm a bit in a pickle here, i got a smart TV (zephir store brand) that costantly loops trough the zephir logo and smarttv logo.
As far as i know the tv fuction perfectly fine until the previus owner tried to performe a firmware update, during the update something went wrong and now we are in this situation.
Till now i have tried the following:
Turning it of and on
Un plug the power and wait for 1h
Tried to perform a factory reset via remote
Tried to perform a factory reset while holding the power button
Tried to perform a factory reset while holding the power button and the volume down button
Tried to perform a factory reset while holding the power button and the volume up button
Tried to connect an usb keyboard
tried to connect via usb to PC
Nothing of the above showed any sing of response at this point the owner has given up on the TV but i still wana try to use it as a second monitor or something, so with all of that i'm coming here to seek the wisdom of the XDA forums. Any and all help would be apriciated form jailbraking to rooting, turning it into a monitor with no android fucionality, how to access the shell file anything at all.
Alright, so I couldn't find any firmware anywhere whatsoever for the Zephir brand. Tried loading a differend brand one for the same logic board. Managed to boot it but the picture was inverted and doubled. Made it to the source selection screen. Attempted to load a different firmware. The tv crashed while loading the booter. Now it won't even turn on the power indicator LED. So I guess it's well and truly cooked.
I could find the board online for like € 40 but I'm pretty sure they come without any firmware or OS? Does anyone know if it'd be worth a try, especially without being able to source the OEM firware?
Does anyone know if there is a way of making just the screen run on an arduino or something, I only need it to run HDMI anyways, 'cause I was planning on using it as a monitor anyways. The logic board is a CV538H-a.
If anyone has a suggestion I'd be glad to give it a go, otherwise i guess I'll bin it.
Hi Guys,
I got an issue with my tv, it's an android tv sony bravia xbr-49x805e, it seems an update failed pr maybe a virus but the home is not working properly, it blinks like it's trying to open an app but then I can't, I tried to unistall apps and it does but when it's restarted it has them again like no changes are allowed.
I've been trying to do the hard reset which according to SONY should be pressing the volume - and the power button while unplugging and plugging again the power cord, doesn't work. So I've been trying to reset the firmware using an USB drive, I was excited because it seem I finally got a solution, however at about a quarter of the firmware update the led at the bottom of the tv flashes in blue an get restarted, the process starts all over again and no solucion.
I'm not sure if this is a software issue or if there's something wrong with the hardware. In case it is a software issue, would you have any advices I can try?
Good morning,
I bought a TCL 32S5200 TV recently.
A problem appears at launch. The TCL logo is displayed followed by the Android logo. A loading bar appears but scrolls to infinity which prevents the use of the TV.
Note that the remote control is no longer functional at this time. It's as if it had no more batteries.
It is necessary to restart the TV several times (by unplugging the plug) to be able to use it.
Is there a solution? Should I reinstall the internal software? If so, do you have a link?
Thanking you,
Hey guys, I've been playing with my device, trying to set up a booting logo (to be mazda instead of android) and the device asked me to update and restart, so it completely froze. No button works, nothing works it's just a screen with green lines, you can see the pictures below. Only the RST hole that I can poke, but it just brings me back to the same thing when it restarts. There's nothing else I can do, so I found a software to update it, I've tried many, with a USB, it brings me to the updating screen but it doesn't move, I've waited for hours with different softwares. What can I do? Is there a better one I can use?
Thank you
