[gsmfriend]

hi friends

I am in need of service manual (schematic) for carradio philips RENRCD200-00

with processor 92CD54IF (from Renault clio DCI)

i have a problem in this carardio :

when I power it ON ,the radio powered on but nothing in display , I think

problem is with SDA SCL lines

can someone help with a solution please

thanks

it work but it don't show nothing in display or it don't work !?

[gsmfriend]

I can power ON/OFF carradio

this carradio contains 24c64 eeprom

the problem comes from :

when I place a 24c32 in carradio only power button light is on , and when press it the carradio powered ON /OFF but not working

Now when I place the original eeprom (24c64) ,always the same problem , but the radio was display "code" on display before I try to decode it

I think 24c32 that I use Is damaged (but I can read/write it with ponyprog) , so it damage SDA,SCL Bus

any comments?

[spider-man]

No it's not possible to damage the bus for SDA, SCL,

eprom structure is same just size is different

so we will try for you to make a code-off or a 0000 code

PS : Don't forget to read rules something missing in your profile

I know they have same structure but size 8k/4k

but when radio power off , I can mesure voltage on SDA is 4.9v but on SCL is 0V

and if radio powered ON SDA = 4.9v SCL = 4.9V (3.3kohm pullup resistors to +5v)

eeprom 24c32 was placed on another carradio and it's have the same problem ,when I place it in this new carradio ,the problem occurs

for that I told you that is a corrupted SDA/SCL bus

then give me pls a code off dump I we will try.

thanks man.

friend , look this strange situation

when I program eeprom 24c64 with your dump and put it in old carradio it's powered on and on display is "ERROR" then "WAIT 99"

when place the same 24c64 in second radio ,it's nothing on diaplay and carradio not working ,

after that I take 24c64 and read it again , I found that a lot of data has changed in eeprom

and here are your original dump and my dump read from eeprom and compare it with file comparer.

I think carradio reprogram 24c64 with inutil data.

pass in pm

[spider-man]

maybe my dump is not correct one for that radio !

[gsmfriend]

of course my friend

because when insert tape in radio ,it display "LOAD CD".

this dump is for CD version

load K7 version please

[gsmfriend]

thnaks problem solved

I have dump , and radio working again

[spider-man]

Ok, try this one too !
i thaught the other one was for tape,

then don't forget to correct location in your profile, because rules say : (Country and city)
