same problem led blink yellow and blue ,BLACk screen i dissolder the eeprom 24c16 ,the led blue FIXed But THE screen is black,there is a way to factory default this f**g eep

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

Well according to the image that Sabre54 put up it's the one on the right in red, their is another that looks like it on the left

yup I tried the button reset no luck

Received my eeprom for my cy199 I-inc after tree tries I finally got it in right
and working. with out hot air it's a PITA.

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

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

Thanks in advance,
Michal W.

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

Only the one i circled needs changing .
Cant remember numbers on the other one but not the same anyway

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?

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 .

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

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

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.

But they are not difficult to change .
Mind you i did use chipquik as i have some left over from another job .

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

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

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

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 .

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

Hi,
I got a cy199 i-inc 19 " screen that when connected shows only blinking blue and yellow led.

The pictures are attached.. I have changed all the capacitors but still no luck..

any idea how to fix this..?

Thanks

Hello everyone I have the same problem and the conclusion to this is an eeprom Digikey part# 24LC16B-I/SN-ND

according to the image of the mainboard The image has two such chips with eight legs which one is the eeprom or are two. eeproms

Thank you

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

is this the rightreplacement pn? Digi-Key Part Number 24LC16B-I/SN-ND

Thanks.

That is a similar part; it may be an exact replacement. What is the number of the part on YOUR monitor.

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

I have sucessfully used Chip Quick to unsolder SMD components. It is a solder with a much lower melt temp and mixes with the solder on the smd. Once it is mixed in it stays molten for a long time and alows the chip to be removed and cleans up easy with paste flux and isopropal alchohal.

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

Thank you guys! I received today a cy199 with blinking blue/yellow and it was indeed a 24c16 problem! On this monitor, somehow, the 24c16 eeprom was fried; I tried to read this eeprom memory in my ponyprog and I wasn't able to; I installed an empty new memory instead and the monitor works! The original eeprom was 24LC16 what means 2,5V-5,5V supply, instead of "plain" 5V in 24C16. I'm not sure if the eeprom was fried because of this... even if datasheet says it works on 5V...
As an advice, try to use a hot air station for desoldering any SMD stuff... a new one starts at 60-70$.

Excellent! Unfortunately I chucked this monitor when I moved, but if the other one I have, fails in the same way, I know how to fix it.

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

I had the same problem. No bad caps, blue/yellow flashing power light. Ordered new eprom from digikey ( 40 cents each, it only takes one, I bought 2 to have a spare ) replaced it. Monitor works now. Just be careful this eprom is very small and very difficult to remove without damaging the board, but it can be done. Found leads to be small and difficult to unsolder. I found that taking a very small screwdriver to unsolder and bend 1 lead at a time out of the way til you get at least one side loose then easier to remove the other side. Easiest way to attach new one was to have a little solder onthe tip of the iron and touch it to the new ones to solder them in. Reason I tried this fix, was I never found anything about a file to reprogram the eprom, so I tried a new one. Tghis eprom does not need to preprogrammed beforehand. Also don't waste your time trying some sort of master reset, I found there was none on this monitor.

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

Any more suggestions for reset procedures?

I've played with variations of the planar link, but no luck.

Also did a full re-cap since I could hear whining, it's still doing it and it still doesn't work. Sounds like it's coming from the PSU, frequency of the whine pulses with the power led.

The eeprom is soldered to the board, removal/replacement is not so simple, but I've got nothing to lose. Any suggestions for the type?

We've one more of these at work, I'll see if I can swap it with another repaired 19" for investigation purposes.

I guess it would do absolutely nothing if I took the eeprom chip off...
