Re: cy199 i-inc showing blue and yellow led only when connected

Hi, is anybody can provide an exact part number for that specific monitor? (I-INC CY199). It looks like I found the fix for my problem with this EEPROM issue. I think I can do the job but I feel unsafe concerning the right part to buy...
Thanks a lot in advance for your advice!

Re: cy199 i-inc showing blue and yellow led only when connected

On your machine do the two chips have any writing on them?

Did you try the button resets mentioned earlier?

Hi just done 2 of these have circled in red the chip that needs replacing.

Once done turn on power and it may flash blue and yellow a few times before it sets up if not turn off and on again .

Of the 2 i did one fired up straight away the other needed turning off and on again .

Anyone know if these eeproms can be reset/wiped without having to remove?

Hello
This is for people that might read this in the future.I repair
LCD Monitors.The INC 199 monitor does lose its hex file as time
goes on creating the blue to yellow flashing light.It can be repaired.
It needs the file and a programmer.I can do this if people want.

Yes I saw that but as you are replacing with a blank unwritten chip it obviously doesnt need programming.
I understand some atmel eeprom chips can be reset by shorting 2 pins SDA and SCL and wondered if it would work on this as well.
If it did work it would be a lot easier than removal

Re: cy199 i-inc showing blue and yellow led only when connected

Well i looked all over net and couldnt find a combination of buttons for a reset,tho someone else may have ?

Also looked for a way to short but again no joy so went the replace route .
But i suppose it would be worth a try and if it did'nt work then can still be replaced .

Hello all,
can be the eeprom "EE24C16P (24C16-10PI-2,7)" use instead of the factory-soldered "24LC16BI SN0646" ?

Thanks in advance,
Michal W.
