This tv have the problem with software
You can try programm eeprom
don`t remembers numbers on the board something 7CD0, 7D...
normaly you must programm Scaler and 2 eeproms 24lc16 and 24lc32
but to programm Scaler you need to have special device Commpair
you can try just programm eeproms
i have files just for 41pf3320
but if you have good SSC tuner board you can just read both eeproms from working board
and programm faulty one. :brinda:
good luck

ok thanks for that.
i checked error codes and it states error 8 ic2 error while communicating with the scailer eprom points to 7c01 eprom as problem.
i have equipment to remove eeproms but the 7c01 ( 24c32 eprom ) what programmer would i need to reprogram as its a 8 leg very very small eeprom ?
or best way to red / write to these very small eproms.

thanks mulja i will try programing them and see how it goes as my new programmer will be here in next couple of days, if i dont have any luck i will send them to you, thanks.
just a bit curious, the top of eprom is marked as 24c32, my new eprom programmer programs 24Lc32 eproms.
is a 24c32 eprom the same as the 24Lc32 as just wondering what the "L" indicates?
best regards.
