Re: Eeprom dump thread!

Heat the processor to 230 degrees for 1 minute and see what it does.
I think the motherboard has a hardware issue not a software one.
You can replace the memory with another new memory.

Re: Eeprom dump thread!

Don't confuse eeprom memory with flash memory !!!. They are different. See what memory you rewrote. The software is for flash memory, spi.

Re: Eeprom dump thread!

I think there is another problem on the motherboard. Most often problems with dc-dc converters or processor. See also if the flash memory is powered by 3.3v.
What are the symptoms of television?

Re: Polaroid TV switch off after logo display

The LED tester is a constant current generator. With it you can light LED bars if they are good. If it is ok, the lights come on.

The D5XXX series is famous for this defect. Try cooling spray on the nand memory. Before starting or immediately after starting.
