eehhh..u pravu je acom..pisemo i tamo i 'vamo..nema veze, ako je problem nek se izbrisu postovi..
sto se ovog tice, sad sam gledao na mom ...jedan stisak button 21 ili ti desno okruglo dugme i odmah me vodi u MENU..evo ti na slikama..pravilno je da izaberes PAL/BG CENTRAL EUROPE, samo tad je 100% kvalitetna slika, svaki drugi standard ne daje sliku osim recimo PAL/BG GREECE i jos neki ali je slika losa...garant ti je to....samo standard da izaberes a ovaj sto ti treba je prvi na listi i potvrdjuje se sa istim dugmetom...
e sad...jel tebi uopste reaguje taj button??? Mozes li da ga proveris u drugim modovima rada..CD, Radio i sl..??? mozda je taster sheban...na primer..kad radi CD okretanjem dugmeta 21 se vidi kako se menja pozicija CDa u changeru..

ps @acom..izvinjavamo se za dupliranje teme..cim zarkic procita..ako Bog da da pomogne. moze da se brise sve sto se mene tice...

eve ga ovaj sa stapicem..uspeo je da popravi jednu hor liniju na ''STOP''

edo, daj mi reci sta si u zivotu prvo radio (pre nego se ubijem) limariju ili dekodiranje.,..jer ako si radio prvo dekodiranje pa sad morao da krenes na limariju ....uradicu ono iz zagrade

vidi u podesavanjima je li postavljen PAL sistem, da nije mozda neki drugi??? Imas ono uputstvo za navi + sto sam izbacio!!!

pozz,

cubica

ma dobro, iz kalka, rucno ili OBD, vazno je samo dobro naplatiti, sve moze da se podnese ali rusenje cena i sl...samo to ne dozvoliti!!!!

eee.ti kenwoodi imaju glupu osobinu da se zaglupe a uglavnom zbog seckanja napona....desavalo mi se 2-3 puta da mi donesu na servis, ja ga prikacim a on proradi jer se u medjuvremenu resetovao sa ponovnim kacenjem na napon. Posle toga nisam ni skidao na astal nego direktno u autu skinem sa napajanja sacekam malo pa pustim opet i proradi..bilo je sigurno 2 ili 3 takva slucaja. ozes i da probas pod napajanjem sa onim reset tasterom iza prednnjeg panela..ako ne uspe, pecni i ti njega pa ce proraditi..vrlo moguce.

a problem sa lampicom ulja...nezavisan, jel tako??

cubica

Tacno tako, desava se da eeprom puca i gubi sadrzaj i treba ga ponovo reprogramirati. Meni se desavalo da pogubi sadrzaj usled oscilacija u napajanju ali i jednom jer je vlaga usla u tablu???
Evo vam sta sam do sada nakupio korisnih stvarcica oko kvarova, i ja se upravljam po tome...pogledajte pa se zabavljajte...ali kao sto kolega rece, samo elektronicari..OSTALI NE PIPAJTE!!!!!!

It's a common problem with this kind of displays !
FET IRF 540 (in the scenic: IRF 3710)
Many 1 ohm resistors...
Poor contact all parts (!) under the glass display - you must to
desolder it !
Check ST 2843B !!!

Hi,
This is common problem...
But the trafo allways seems to be bad, but it is good
Change the pwm controller (2843B) to a new one.
Check the pin 6 and the 30 ohm resistor.
Check oscillator frequency, must be 52 KHz.
And all soldering

Your bench power supply must be 6-8A or better, i use lead acid accu 7Ah/12V. You must connect pin 1 of Red connector to +12V via R=1K and dashboard will start only clock, but this is enough to see that work or not. Start current is critical.

Hi
I don't understand where is problem ???
this instrument is really not complicated !!!

step1
check smd fuse - if is o.k. then try resolderin pcb (1ohm resistors and everything around)
try start instrument with 1k resistor
if working clock - check current 1.2 - 1.3 A.
if more then something is not o.k.

step2
if smd fuse is not o.k. then check transistor F3710, resistor 30 ohm and CS52843 (look data sheet)

step3
lot of instrument clusters to lose eeprom software. without correctly software cluster not starting as well, sometimes is different milage. noise from converter.
reprogram 93c56
v5.14 or v6.01 or v6.02

hello all!
I have a dashboard of renault scenic II no display, I disloder big cristal, I tested all smd resistor (0ohms) all good, small fuse is good too.
where is the problem please.
how to confirm f irf7310 is good or no?

help me plz.
thanks a lot

you can try measure it with a multimeter

First, identify the gate, drain and source pin from semiconductor data book.
Once you have locate each pin of the fet, then use your analog meter set to times 10K ohm range. If you are measuring an n-channel fet then place the black probe to the drain pin. Then touch the gate pin with the red probe to discharge any internal capacitance in the fet. Now move the red probe to source pin while the black probe still touching the drain pin. Use your finger and touch the gate and drain pin together and you will see the analog meter needle will kick forward to middle range of the meter's scale. Removing the red probe from the source pin and touching it back again the source pin the needle will still remain at the center of the meter's scale. To discharge it you have to remove the red probe and touch one time on the gate pin. This will discharge the internal capacitance again. Now using the red probe to touch on the source pin again, the needle would not move at all because you already discharge it by touching the gate pin.

I know is a little bit of confusion but after some practice you will be able to test all types of fet.

When measuring the fet and you observed all the readings moved toward the 0 ohms range then the fet is considered shorted and need to be replace. Checking the P-channel is similar to checking an N-channel fet, just switch the probe polarity when measuring the P-channel. If you having an analog multimeter with a times 100k Ohm range, then you might not be able to accurately check the fet due to the missing of 9 Volt battery in the meter. The missing of 9 volt battery will have not enough power to trigger the fet. Make sure your meter have the time 10k ohm range. Typical N-channel fet part numbers are K792, K1118, IRF630, IRF 840. P-channel fet part number are J306, J512, IRF9610 and etc.

If your dash is starting intermitant, then the eeprom is not the problem (i have experimented with eeprom contents and found that there is only 2 address which hold power up data, i dont think the data is the same for every version of dash, needs more research). The only corruption i have seen is the milage jumping up or down, but i feel the eeprom stores parameters for the particular model of scenic, ie:- electric handbrake, auto gearbox,launguage, etc (someone correct me if i am wrong)
Ok i am attaching a pic with voltages i read on a dash i fixed, if you have voltages like these and still no display then i would assume there is no coms from dash to vehicle ??.
I also took pictures of ossciloscope readings from pwm, i will upload as soon as i find my usb lead.
Hope this helps

aaa..nemam pojma nije mi se onaj javljao..i bolje ionako ne znam gde se nalazim.. 

cubica

....ma sve sam bio odradio kako treba i javilo mi da je podignut file ali sad..kad ne mogu da vidim nista..ali neka..evo klickam post po post pa cu valjda i progledati jedan dan 

cubica

pogledajde ovo, odnekle sam sacuvao za ne daj Boze..mozda pomogne.

srecno,

Evo jedne, maaada, kolega je u pravu, ima bas dosta toga po netu, samo da se sedne i buba.
