If you're trialling a 1 blink error and you have access to a 42" board, you could save the original file of the 50, copy from the 42 and then write that copy to the 50. If it cleared the fault it would be safe to assume the original was corrupted
Here's a couple of dumps from a 42" model could be C2, X2 but HD series same board number if you want to play.
Can't verify if these are corrupted but they are the contents which I copied and then verified matched the chip contents.
They are of a board someone donated to me which I presume defective.
IC9304 is the panel address data, don't know what 9001 is.
My advice is copy, backup and verify first the chip contents you intend to write over just in case you get a bad read from a bad clip connection.
Also pay attention to the chip type, brand and model etc as one is a 24 , 9304 is a 25 and you will have to plug the lead into the ch341a the right way or it will short.

Look like My Ic 9001 is dead. Can not read and write it I will find new one , It is 24C64, Hope I solve problem. I do not know why it is dead.Not corrupted but dead. All data are FF.
I did remove the 9001 from the panasonic tv board that has sos1. The ic is bad. programmer does not read and write to this ic.I use the test pad of this programmer.
