Može biti, probaj, što kaže Miki probaj da li dobija napajanje sa 1 i 2, 3.3V, ako je to dobro ostalo nije problem da se proveri, mada verujem da je pinout standard. Smile

Evo već sat vremena guglam i ne mogu naći u čemu je razlika izmedju UC3844A i UC3844B ?
Zna li ko ?

*****************

Evo i odgovora na: http://www.ti.com/product/UC3844A
- samo da sam pažljivije čitao ...

The UC1842A/3A/4A/5A family of control ICs is a pin for pin compatible improved version of the UC3842/3/4/5 family. Providing the necessary features to control current mode switched mode power supplies, this family has the following improved features. Start up current is guaranteed to be less than 0.5mA. Oscillator discharge is trimmed to 8.3mA. During under voltage lockout, the output stage can sink at least 10mA at less than 1.2V for VCC over 5V.

Hvala emiSar!
Baš mi treba neko ko dobro poznaje televizore i razlike među modelima.

Pravim Fankeštajna Samuki. Dobio sam ispravan LCD TV sa polomljenim ekranom a na oglasima našao neke crknute sa ispravnim ali sličnim ekranima pa da vidim kakve su mi mogućnosti...

He he Franki pravis, ako ne nadjes displej u oglasima probaj na Ebay, tamo ima svega ako imas otvoren racun.

Nema ga.
Potreban mi je panel LTF400HM05 ili neki kompatibilni (ukoliko postoji) za Samsung LE40D503.

Poslušao sam te emiSAr i postavio pitanje tamo gde si mi predložio... Smile

Do sada mi je tema samo premeštena dva puta, jer sam je otvorio u pogrešnom delu foruma, i to je sve... Smile

Nisu "moji". Alexa_pg se ponekad javi i na ES i na elektronika.ba i uvijek ima konkretan savjet.-
Sto se tice Samsunga, najveci svjetski proizvodjac panela. Mnogi znani i neznani nam televizori i monitori
koriste njihove panele.
Sin kad je kupovao "odrasliji" monitor, kupio Panasonic sa Samsungovim panelom, kaze ima bolju
elektroniku i kontrole.
Kako je Samsung televizor, sumnjam da postoji neki ekvivalent za zamjenu.-

Primetio sam da je alexa_pg jedan od moderatora...

U pravu si.
Ono što sam uspeo da iskopam na netu je da neki različiti modeli koriste istu matičnu ploču što povlači sa sobom da su im i ekrani isti ili kompatibilni.
Pokušaću da iskopam još detalja na netu. Potrebno je samo mnogo kopanja...

Baziraj se na Philipsa. Samsung je krenuo kao istocna filijala. Dok sam petljao oko TV aparata, bilo ih dosta sa istom sasijom i kompatibilnim daljincima.-

Ima li ko pinout od CCFL invertera :
NCGIN1000 iz Asusa A6R ?

http://www.lcdparts.net/InverterDetail3D...uctID=1736
https://www.google.rs/imgres?imgurl=http...MwgdKAEwAQ
http://www.ncb.pt/catalog/product_info.p...anguage=en

Znači, zanima me funkcija svakog od 10 pinova na ulaznom konektoru ?
(mislim da je isti pinout i na NJGIN1000)

Već duže vrijeme gledam da si napravim neku malu motalicu. Gledao sam na ebayu snažnije motore sa malim brojem okretaja ali to košta(možda par $ ali košta Tongue ), a zašto plaćati nešto kada kod kuće imam step motore i svu elektroniku na lageru. E sada dolazimo do problema. Našao sam ovu šemu.



Šema radi onako kako bi trebala, LEDice se pale po redu i može se mijenjati frekvencija PWM,znači brzina okretanja motora. Sada dolazimo do problema kako spojiti step motor? Imam motore sa 6 izvoda, znači 4 zavojnice od kojih svaki par zavojnica ima srednji izvod. Znam koji su parovi i koji su srednji izvodi samo kako to čudo spojiti a da se motor okreće,a ne kao u mom slučaju napravi jedan pomak lijevo,pa desno i tako unedogled. Ne znam koje sve kombinacije nisam probao ali bez uspjeha,ili da napravim tabelu i probam sve i jednu kombinaciju i križam one koje ne rade.

Evo i sklopića napravljenog na proto boardu.
