Re: Mainboard change F8500, EPPROM debug

Progress: 1. In the meantime I studied and found out that on this TV the "main" board is unified with the "logic" board. The "logic board" is in part responsible for the link between the main board and the panel. 2. There is a Samsung service bulletin ASC20150408001 about another issue but the inter...

Mainboard change F8500, EPPROM debug

Hi I am trying to install another mainboard on Plasma F8500 (the mainboard came from 64" and my TV is 60"). So far I have only audio and remote keys response. Using the old mainboard that partially works I have some decrypted the EPPROM values to check/set the main settings. (type, local set, tuner,...

Re: EEPROM PN51F8500

Yes, i completely agree, ATMEL S24C32 is our target. No doubts. I found the EEPROM on S24C512 under the lower metal radiator (meaning towards down side of the tv). I will add pictures. I know it is this the EEPROM as I have studied the EEPROM research done by you before on D panel and then tested u...

Re: Change mainboard, EEPROM reset

Step 3: EEPROM reset (having it already saved and verified before) between pins 4 (GND) and 5 (SDA), after verifying the pins specs for this chip. http://ww1.microchip.com/downloads/en/devicedoc/atmel-8720-seeprom-at24c512c-datasheet.pdf I repeated and same result. I am not sure how to check if it w...

Re: replace 55f7500 board with 60f7500 board of different region

Old topic But I would like to add my recent experience: YOU CAN SECURELY exchange motherboards between different tv sizes but within the same series.. Usually these motherboards DIFFER ONLY in the last letter pe Mainboard Samsung UE60F7000SLXZF BN94-06186D AND Mainboard Samsung UE46F7000 BN94-06186...

I also checked with another firmware, consisting of only 0xFF, with it the TV starts up and offers to manually restore everything in the service menu.
do you mean EEPROM content "consisting of only 0xFF" will make the TV to offer the option of restore everything in service menu?

Re: Change mainboard, EEPROM reset

Status: With other mainbords from other TV dimensions, the TV is starting but the mainboard has a flasing error 5 times. Then the TV is receiving remote signal and is reacting with sound part but no screen. If I put the same mainboard from same screen & region then the TV is working fine. Back to tr...

Re: Change mainboard, EEPROM reset

In the mean time I found the EEPROM - hidden under a heat sink: S24C51

I have the tools to read it and I would like to check the info for local set, type and region.

Could anybody help me with the EEPROM content from PS51F8500 or PS64F8500 or PN51F8500 or PN60F8500?

Thanks
