Blaupunkt TV Firmware issue. BS49E148BFJ0U0K10M 0 display only splash screen

Question

I have a
Blaupunkt BS49E148BFJ0U0K10M
T.MS3463S.771 main board
LC490DUY-SHA1 Screen
PCB:MIP550D-240V350 power board (Megmeet.com)
I think I have a firmware issue, the TV comes on and displays the Blaupunkt splash screen, then after around 40 secounds it goes off and then comes back on to display the same again. The picture is good and back lights strong.
I cannot find the firmware to reinstall and see what happens.

Can anyone help?

Hi, thanks for the link, they sent me a file and I installed it but it has made no difference.
TV turns on and shows the splash screen with the Blaupunkt logo, after about 40 seconds it goes blank and the standby light comes on, then it comes on again with the splash screen.
The remote is working but the TV is unresponsive to it.
Anyone got any ideas where I can start with this?
Probably a main board issue but is there any other possible solutions?
There are also no sounds at any point of any kind of relay click!
Thanks mechsteve

How did you update?

mechsteve · Answer

HI, I copied the bin file they sent me onto a freshly formatted thumbdrive (fat32). Unplugged the tv, put the thumbdrive in the usb socket and then turned it on. After a few seconds the thumbdrive started to flash steady, like it was being read. After around 4 minutes it stopped flashing. I tried the remote but nothing. I turned it off at the switch and removed the drive. Turned it back on and found no change.

Have you measured the hdmi ports if they are shorted?

mechsteve · Answer

No I haven't. Thanks for the tip. I will check them. Is there a preferred way to do that?it's not something I have done before! I'm only a hobbyist at this.

querij · Answer

If you don't recover the software, you probably have a damaged flash or microprocessor.

Post a dump for analysis.

Can you please provide the full serial number? I'm trying to get help from Blaupunkt support

mechsteve · Answer

Thanks. BS49E148BFJ0U0K10MFrom the other comments it is most likely the main board and even second hand it isn't worth the cost at around £70.But thank you for your time, it is appreciatedDodano po 2 [minuty]:I can't get a dump file as it won't turn on past the splash screen..?

Search for a guest from Sucha Beskidzka is announced and has all the dunks for the LCD

janomo · Answer

It is best to program a new memory in an external programmer with the received file. Attempting to update the software with a pendrive may fail, especially if the memory on the TV is damaged. Alternatively, contact your colleague: e-mail from Sucha Beskidej - he is the best in these blocks.

mechsteve · Answer

Sorry folks, not solved. Friend decided to bin it and so no repair made.Thanks for all your tips and help
