Sony KDL-55W805C infinite reboot help needed

by keristos

Hi Guys,

Would really appreciate some help and insight into the issue I'm facing.

  • Wife called saying TV isn't turning on and keeps restarting
  • Get back from back and, well, she's right
  • I notice it's rebooting after a few seconds, sometimes reaching the Android logo (not the floating dots, but android being written with colourful lines etc...)
  • I try pressing Vol down + power on on the back of the TV - this shows a green LED for around 3 seconds and then continues in the reboot cycle. -I try turning the TV off for a while, pressing Vol down + power on and then plugging in the TV. Same result as above. -I tried downloading the firmware from here and placing it on 3 different USB files, all tried in different ports. The TV does not recognise any.
  • I tried renaming the firmware to upgrade_uploader.pkg - no difference
  • I tried the sony_fw_2014_RECV_STEU1.pkg - no difference

I finally got help from someone on a sony forum and after going through all these steps again whilst performing some checks the (partial) solution was to format the drive using the windows command Diskpart and the following:

  • list disk

  • select disk TYPETHEDISKNUMBERCORRESPONDINGTOTHEPENDRIVEFROMPREVIOUSCOMMANDHERE

  • clean

  • convert mbr

  • create partition primary size=2000 offset=1024

  • format fs=fat quick label=2GB_FAT16

  • assign letter=s

  • active

  • exit

This showed the 'updating' screen on power on, but after a minute or 2, when the bar reaches about a 1/3 or 1/4 of the way the LED flashes blue, the TV reboots and the updating process starts afresh.

Any ideas please?

Get it serviced. Bootloops are almost always caused by solder failing somewhere (generally the SoC) as seen with the LG bootloop fiasco that plagued their devices for years.

It could also be an eMMC failure if it’s doing it at the same point in the process every time you attempt the recovery.

Either way, this issue is almost always a hardware problem unfortunately.

This is why I'm not fond of Smart TVs. Manufacturers should at least build in a failsafe that allows the TV to still function as a basic TV should something like this happen. Had a similar experience with an eMMC failure on my TV that stops the TV from booting.

That said, your issue could be a range of issues, but if you can get it serviced at all definitely do that.
