Eeprom dump thread!

Re: Eeprom dump thread!

it seems that if the chip is blank it shows
recognition error
i am now able to write to chip
but it only took a few seconds to write is that normal?
i expected it to take more time?

Re: Eeprom dump thread!

Eeproms are written quickly, but there should not be a recognition error, most likely you have not recorded anything.

Re: Eeprom dump thread!

jimbofz: in those Chinese tvs, if the only issue is no sound the problem is the sound amp, make sure the sound IC has power before replacing it, if no sound after replacing it then the issue is the microcomputer.

thanks for your post ,
i have made a note of the sound o/p ic problem
sadly my fault is dead but all supplies ok no sby light

What's the problem with the TV?
What is your motherboard number and what is the panel (matrix) number?
You can read the data (dump) from your eeprom and post it here.

Re: Eeprom dump thread!

Thank you so much! You are a genius.
I wonder if you can change the panel in this firmware, Mainboard CV3393BL-C original panel is HV236WHB-M00 but I need the V236BJ1 panel,
the reason is that I need to flip the image, or how can I flip image? Service mode don´t work

Service mode doesn´t works

Why does the service mode not work, or do you not know the code how to enter it?

I can enter and modify but the changes disappear when I turn off the TV

there must be function to save changes. try with ok or (>) arrow button or vol/channel + button.
