Question Why you need to programming the TV Mainboard?
Answer: Just Because the TV is can’t start-up problem, so I want to try programming the Mainboard and solve the
problem. Or I want to copy their firmware to prepare future use. These two
answer is most of the TV repairer gave.
Q1: How to Programming the TV Main Board?
A1: Normally the Programmer when using the ISP (Online programming), it will go to detect their Flash memory. The flash memory is mean of the external
25 series Flash memory IC on Mainboard. So the Programmer software will
shows like 25 xxx detected and prepare to Read or Write command.
Actually we can remove the 25 Series Flash Memory directly from Mainboard
and to do the Offline Programming to Read (Copy) their firmware/data from the
25 series Flash Memory IC. And then save the firmware into the computer/laptop prepare for future use.
Q1: How to Copy the Firmware from Main Board?
A1: Like a said on the above, you can remove the 25 series Flash Memory IC
from Mainboard and to do the Offline Programming. After click on the
Programmer Software button “Read” (Copy) the firmware from 25 series Flash
Memory IC, and then save it into the computer/laptop.
Also don’t forget their NAND Flash IC. It also can cause the TV can’t start-up.
If you want to programming the NAND Flash memory IC, please do carefully,
because some of the NAND Flash IC need to programming their MBOOT or
BootLoader first, after that is the main firmware for that NAND Flash Memory
IC. Also for programming the NAND Flash, you need choose a Pro Programmer like RT809H to support this type of memory IC.
When we change a new Universal TV Mainboard to a TV, we need to change
the firmware to suitable of the TV Panel Resolution and model. If not, the TV will no display, fizzy color and display & etc occur.
So the Universal TV Mainboard has their own firmware list to suitable different
Panel. If you buy a new Universal TV Mainboard, make sure to tell the seller
your TV panel part number. After the correct version and panel types firmware
is ready, just copy that file into the USB Pendrive USB Flash Drive and follow the instruction to update the firmware to the latest one to suitable the TV Panel.
Some of the Universal Mainboard is built-in the different Panel type firmware.
Just follow some instruction to change the Panel type without using
Programmer or USB update.
Before to programming the firmware, make sure these firmwares you get are
same as your TV:
1) TV Model
2) Mainboard Part number (Important)
3) Panel Part Number (Important)
* For example: If the firmware same
Samsung Tcon Voltages Testing
Mainboard Part number but not same the Panel Part number. If that Panel part number also show the same inches Panel,
then you should give it a try. Make sure that you backup you old/original firmware first!
