fu fl32050 is continuously stuck on logo
hi on this tv with mainboard el.ms3663s-fe48v1
and display cx320dledm
does anybody has flash dump file ?

[lotas]

Post your dump here and I'll take a look.

[wolf1976]

where sir lotas ?

[lotas]

where sir lotas ?

What do you mean where? I say that you should consider the programmer to be your own dump from your TV, save it and post it here on the forum, I will correct it.

[wolf1976]

ok i understood with programmer i must take the dump

[lotas]

ok i must take the dump

Yes.

[wolf1976]

hi
just to know if its possible
can i use ch341a for upload the original flash file without remove the chip or its better to remove the chip because its dangerous for mainboard if i connect direct on chip via the special cable of this programmer ?

[lotas]

It is better, of course, to remove it and read it through the adapter on the programmer; reading and writing errors may occur through the clothespin.
If you are afraid, try reading the dump through a clothespin, you need to read it several times and all these dumps files must be the same and the checksums must match, if the checksums are different, then it is better to unsolder...

[wolf1976]

sir, since you say that it is better to remove it, I will do so to be sure

[wolf1976]

hi again
as about as my problem i noticed that sometimes while takes command from remore control it doesnt light even backlight the display is bleck and sometimes
appears the logo and remain on it
the trueth is i didnt take the file because i have a difficult to understand what is the eprom i upload photos just to be sure

[lotas]

Yes, that's her. But this is not an eeprom, but a spi flash analogue of 25Q64.
Eeprom is 24Cxx
Spi Flash is 25xxx.

[wolf1976]

ok from this component i must have to take the flash and upload here right sir ?

[lotas]

Yes, carefully unsolder it from the board and read its contents (dump), save the file xxx. bin, pack it in zip or winrar and post it here.

[wolf1976]

ok i will try

[lotas]

I hope you know how to use a programmer?

[wolf1976]

yes sir i have watch video on you tube

[wolf1976]

something last i want to ask before try read the program
i will use ch341a and when i place the ic spi flash to the programmer
can i use the tab detect doirect and after the read ?
or will i have to set someone level of voltage 1.8 or 3.3 volt ?
i ask so i will ensure i dont damage the ic

[lotas]

What program will you use for CH341A? This flash is 3.3v.

[lotas]

IC-SPI_NOR-EON-EN25QH64
