Blaupunkt 50" LED TV firmware please

Re: Blaupunkt 50" LED TV firmware please

check the electrolytic capacitors near the connector on powerboard, the one with the cable from powerboard to mainboard, maybe one or more bad/weak, also check all your solder joints on the underside of board, examples of bad joints there: https://www.google.com/search?q=bad+...ih=607&dpr=1.5

Re: Blaupunkt 50" LED TV firmware please

Was interested to know what happened next, I have same TV but a weird problem ithink capacitor may have gone weak since it takes turning it on about 10 times for it to stay on and number of times seems to be increasing day by day , started to leave it on all night in radio mode, now it turned off and won't stay on beyond the logo, and doesn't get to blue screen if no signal

Re: Blaupunkt 50" LED TV firmware please

Well, decided to order another board so at least its up and running again. Eliminates power bd and panel etc..
Accessing terminal via uart I am able to do nandbin, nandbin2 & nandbinall which gives me
CIS_BFN.BIN
KL.BIN
MBOOT.BIN
MBOOTBAK.MBO
NAND.BIN
NAND.DEF (only 1kb?)
PART1.BIN
RTPM.BIN
UBI.BIN
UBILD.BIN
UBIRO.BIN

Can these be used to create an .img file to recover the old board? or is there a way to create the restore .img file that I'm missing?

Meanwhile I have ordered some parts to hack up an interface to the tsop48 nand in-circuit to attempt a dump to flash to the old board.

Re: Blaupunkt 50" LED TV firmware please

What I need to work out is how to change uart debug to off in Service Mode in debug mode.

Re: Blaupunkt 50" LED TV firmware please

I have at least now managed to connect via Usb-Uart, but what I do now is a mystery.
Connecting with a blank USB stick gets the filenames its looking for...worth noting for future reference.

Re: Blaupunkt 50" LED TV firmware please

I suspect the data you changed in the service menu is stored elsewere,(maybe in the same nand/spi/eeprom) and upgrading or replacing the firmware is not changing that data. That way when firmware is upgraded, important data is not changed.

[notallbad]

Re: Blaupunkt 50" LED TV firmware please

No, still not fixed.
Just stating what I provided for the file.

[vinceroger69]

Re: Blaupunkt 50" LED TV firmware please

It was necessary to provide the Serial number from the label on the rear of the tv, the file received was only 34.3mb.

you got the set sorted? i wonder if that was just like a software upgrade and not the full firmware files you need

Re: Blaupunkt 50" LED TV firmware please

i wonder if yokoono or diah can offer any help as into why the firmware update is not working on your tv it should be the correct files as direct from umc etc odd its still boot looping though.

[notallbad]

Re: Blaupunkt 50" LED TV firmware please

Yes I believe it is the correct board though would be useful to know whats on the reverse side of the board.

[vinceroger69]

Re: Blaupunkt 50" LED TV firmware please

was that replacement mainboard in the link the rite one? it seemed a good price and was open too offers.

[notallbad]

Re: Blaupunkt 50" LED TV firmware please

Fat32 formatted and only the update/ upgrade files is the normal procedure which is what I did, unfortunately not being able to access the menu i.e unresponsive, the only option was to plug in the usb stick and power on. As I've said, it appears to be doing the upgrade process and completing.
I did check the usb ports havent got anything stuck inside making the tv think theres still a usb stick still mounted.

[vinceroger69]

Re: Blaupunkt 50" LED TV firmware please

Yh, def removing the usb then powering off then back on.

I havent tried another usb stick, currently using a 16gb stick, I guess thats a possibility, its not recognising the usb has been unmounted?

This is the guide they sent me to update firmware

[dick_barton]

Re: Blaupunkt 50" LED TV firmware please

I think the USB stick has to be formatted as FAT32 with only the update files on it.

Re: Blaupunkt 50" LED TV firmware please

Wow, fast response, file received already.
Unfortunately after it does the update the tv just power cycles (around 1 min) by itself with an unresponsive blue screen after the 'Blaupunkt' splash screen.
Remote control and keypad has no effect.

once the upgrade is done and the tv restarts are you taking the usb stick straight out im sure i had this issue and all it was i wasnt removing the usb stick once update had been done hence not booting fully

Re: Blaupunkt 50" LED TV firmware please

Mainboards seem quite cheap if this is the correct one i would make him a offer

Re: Blaupunkt 50" LED TV firmware please

No, but think they only have limited knowledge i.e providing fw only, perhaps staff levels are low currently.

Been scratching my head all day over this.

Unable to get a Uart connection via vga port so guess thats not wired out on the board and no other obvious connections.

I also attempted to unpack the .bin file but only to get 2 header files, a lot of other stuff missing so unable to investigate the bin file either. Need to do more research on this.

I do have a rasp pi so intend on trying to read the nand that way but at the moment have no way of connecting to the nand on board (a '360-clip' looks ideal but pricey) though I think a replacement board is in order to at least see it up and running again and to prove everything else is ok. I have no intention on attempting to upgrade the fw, thats for sure! Then again if I can get a board cheap enough I might be tempted or stoopid enough to!

[vinceroger69]

Re: Blaupunkt 50" LED TV firmware please

pity neither sorted the issue out though did you mentioned you altered something in the service menu by mistake? so i would of thought reloading the firmware would of solved it
