Did you replace it?

No, unfortunately, without replacing, just tested if that works
I am looking for a dump file

Hi,
I am searching a working firmware for this TV Telefunken D49F283N3C
Does anybody have a firmware or eeprom dump.
With the versions from other sets the screen is upside down and distorted.
Panel VES490UNDL
Any Idea how to change timing parameters for that on the 17MB95 Vestel board?

Luckily I found a firmware version that worked. "27109709_MB95_3_VPAZ_HO_Phase3_V329r_SVN_119613_ENVIR_GEN.xls"
To install it i had to change the "usb_auto_update_A1.txt". I deactivated this line "spi_ws 0xFF00" because it was showing up as error in the serial panel.
Although it is for a 40" Vestel display it works flawlessly with my 49" as well.
At first the SAT tuner didn't work but either it fixed itself or the hwprofile and swprofile.bin files i still had as backup cleared the issue.

Using the serial interface (Scart) to see whats going on helped a lot - that way you clearly see what happens.
