Toshiba 49U6863DB blinking red/green power indicator

[mad_philly]

Hey all,

I have a Toshiba 49U6863DB with a blinking red/green power indicator, although it's intermittent. I went through https://www.badcaps.net/forum/showthread.php?t=45796 which is the same issue on another model.

There are no online updates per the settings menu and I cannot find any firmware for this model, only software from Vestel. I downloaded this and extracted to a blank FAT-formatted flash drive. Turned on the TV and inserted the drive. Media browser popped up and of course didn't recognise the files. Tried powering on with OK pressed but that didn't seem to do anything.

Any tips for this model?

Many thanks in advance

the wrong you are in,
1- that USB drive should be inserted in TV USB ver 2 not V.3 blue one while the set out from wall socket.

2- the USB drive should be Formated FAT32 in MBR mode. so it will boot up

how to Great Bootable ( MBR ) USB Flash drive.:

using “diskpart” at windows PC
Launch the “diskpart” or “diskpart.exe” utility from the Windows Start/Run menu or the Command Prompt (CMD)
# Show all disks (hard drives or removable media).
DISKPART> list disk
 
# Select a disk yours USB drive.
DISKPART> select disk [number identifying USB flash drive]
 
# Delete all partitions, resulting in a blank disk.
DISKPART> clean

# convert the USB Flash drive to MBR
DISKPART> convert mbr

# Create a primary partition (using MBR).
DISKPART> create partition primary

# Show all partitions (should just be the one newly-created partition).
DISKPART> list partition

# Select the primary partition to operate on (only 1 partition exists).
DISKPART> select partition 1
 
# Make the primary partition active (aka bootable).
# This command will fail if the USB drive is using the GPT layout.
DISKPART> active
 
# Format the active primary partition using FAT32.
# To do a full format, instead of a quick format, omit the "quick" flag.
DISKPART> format fs=fat32 quick
 
# Assign a drive letter to the primary partition
# (just in case Windows didn't already do it).
DISKPART> assign

# Quit DiskPart.
DISKPART> exit

at end copy the firmware you want to flash and start with Point 1 + pressing OK on RC while you plug the set in wall socket.

I don't have a blue USB socket. Both are the same. When I plug the TV in holding OK, nothing happens, in either socket.

if you did as i explained about MBR. then the firmware you have not bootable to recover the TV. so you need to seek after recovery firmware.

Re: Toshiba 49U6863DB blinking red/green power indicator

BTW: a full firmware to recover the tV should contain at least 4 files.

mb130_en.bin
mb130_PM51_connected.bin
mb130_RomBoot_AMZ.bin
usb_auto_update_G10.txt

you can try this

Re: Toshiba 49U6863DB blinking red/green power indicator

I did everything you suggested, including MBR.

Here are the files I have...

Mode         LastWriteTime     Length Name
----         -------------     ------ ----
-a----    14/04/2021   13:13   181906690 mb130_en.bin.gz
-a----    14/04/2021   13:13     65536 mb130_PM51_connected.bin
-a----    14/04/2021   13:13    2242560 mb130_RomBoot.bin

Re: Toshiba 49U6863DB blinking red/green power indicator

are you using mac or Linux distributor ?

between the first file are still compressed (mb130_en.bin.gz)..... it should be (mb130_en.bin)

[mad_philly]

Re: Toshiba 49U6863DB blinking red/green power indicator

Neither - Windows 10. Should I extract the .gz?

sure, if you extracted it and give you one file only "mb130_en.bin" then fine.

Re: Toshiba 49U6863DB blinking red/green power indicator

Okay, so I did that and still nothing.

it could be one of those.
1- did you tried the links i gave you before?
2- your RC didn't work, or the set flashed before the eeprom section with other firmware than Toshiba so the RC will not work. ( need to use android device with IR sender and smart remote apk)
3- you have hard ware issue on mainboards .. eeprom or nand. or also could be BGA.

4- upload here yours file "usb_auto_update_G10.txt" to inspect it

I'm a little concerned as to whether this may brick the TV if it's not compatible?

I've attached the txt file

are you sure the firmware you have now are compatible ??? you wrote its for vestel not toshiba.. and the one i linked for vestel too.. only you need to compare your panel No. if its match. as its written on the firmware which panel its.

Valid point!

Here's where I got it from and it denotes it's for my TV model.

I'll have to get my hands on an android device with the IR sender and try that. Would it not work with an iPhone?

its work only with Android mobile with IR sender such galaxy s5

which size your usb flash drive you are using?

write down yours Panel No.

Re: Toshiba 49U6863DB blinking red/green power indicator

I'm using a 4gb drive. How can I see what my panel number is?

take out the back cover, you will have it as label on the chassis
also read yours mainboards type is it 17MP130S ??

Re: Toshiba 49U6863DB blinking red/green power indicator

Board is indeed as you suggested. I tried with my old S5 mini with a smart tv remote, no luck.
