pozdrav svima, malo sam u problemu imao sam tablu za renault scenic johnson controls, palila mi se i gasila u voznji to sam rijesio imala je previse hladnih lemova na procesoru i na napajanjima, ponovo sam dobio takvu tablu samo s drugog auta, ne ponasa mi se isto kao ona li uglavnom i ona se gasi, pregledao sam je svu svi vodovi su uglavno bili dobri nasao sam jedan bio otpornik neispravan ali tabla i dalje mrtva, pa bih trebao strucnu pomoc od iskusnijih kolega. Hvala unaprijed svima.

rijesena tabla trafo crko i IRF. Riješeno.

Pozdrav raja
za Pecirepi a naravno za ostale:
Ako je elektronika uredu (Mislim na sva SILNA lemljena, fet-tranzistora,ic-a) a tabla i dalje ne svijetli onda Pristupite Koraku 3
prva dva koraka æu objasniti kasnije a odnose se na obiène ljude sa osnovnim znanjem iz elektronike
Korak 3
Reprogramirajte Eprom 93C56 sa odgovarajuæim sadržajem (dump) U epromu se nalazi osim podatka o preðenim kilometrima i software za rad procesora na tabli.
postoje 3 verzije damp-a i to V5.14;V6.01;V6.02
verzija software-a je naznaèena na samom procesoru.

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

Zanima me jedna stvar u vezi ove table a to je gdje nabaviti trafo za ovu tablu?
Pa eto ako netko zna molio bih da mi kaze ...
Hvala unaprijed....
Offline
mozes sam trafo da premotas nije tesko uradio sam ja 3-4 trafa do sada i nemaju problema,nema unutra vise od 3 metara zica
Offline
A kako znas da je neispravan trafo, osim ako se nije zapalio?
Ne nastojim biti jeftiniji, nastojim biti bolji!
Offline
I mene zanima isto...nisam nesto mnogo ovih tabli odradio alèi nikad do sada nisam naleteo na trafo neispravan..mozda i bolje Te stvarcice se ne kvare lako i kako rece Elti moraju da gore i spajaju namotaje..da li su bili makar vidljivo pokvareni..nagoreli..da li si merio otpor namotaja i poredio sa originalnim ili..??

Drugari,
Obrisao mi se eprom iz table Reno senic 93c56 verzija 8.90.
Ima li neko damp za ovu verziju?
Na displeju javlja erorr eprom.

Ne znam zasto ti to javlja? damp koji sam okacio je od senica 1.9 dci doduse iz 2004 god ali je od tog modela. Jesi probao da zamenis eprom drugim?

Ljudi ima li neko damp za ovu Galsku kociju ili da kupujem tablu?
Stegla zrtva za gusu,udavi.

Jesam isto mi javlja
mozda si ga kontra postavio ili ti je prolikom dizanja puklo podnozje na plozi , vidi imas li napon na epromu ,
koji programator koristis ?

Ima li neko za scenic 19dci 2003 v5.0c dump
Niko nije naveo,ali treba proveriti i elkose od 100uF.Nasao sam jedan los ,ali i ostali su sumnjivi tako da bi i to trebalo menjati.
Sve se to fino greje pa je i vek elektrolita znatno skracen.

Nije do dump-a .Skinuo sam stari ako nekom zatreba.

Ima li neko trenutno ovu tablu na servisu da mi premeri otpor izmedju pinova 1 i 4 na slici? Sumnjam da tu sme da postoji ikakav otpor a kod mene ima 70 ohm.

Skinut mi savet sa foruma,mozda zbog broja telefona da me podsetis jutros,ali nema veze setiosam se sam,u jednom smeru ti ima 11oma a u drugom nema nista,probaj dici nogicu u vis pa probaj da vidis razliku.Sacu da moju tablu prikacim i da ti posaljem koji je radni napon na toj tacki.

Reseno.Pored gresaka koje su ceste na ovim tablama bila je i ova sa displejem.Izmedju pinova 1 i 4 ne sme da bude nikakvog otpora!
Kratki spoj je izazvao pregrevanje i otkazivanje napajanja table.

pozdrav ekipi ima li neko displej ovakav posto imam jedan sa istim problemom,ako ima neka se javi
