Telefunken tv repair

Recommended Posts

Hi,
I have a problem with my Telefunken television.
If I connect to power turning on and only changing colors.
Tv modell: Telefunken d48f282n4cw
Source of the problem probably the current fluctuation.
Can you help me how can I resolve this problem?

I have bought a main board and it does same thing.
Is it firmware related?

Thank you

Edit moderator: Colegul zice că acest televizor la pornire doar alternează culori pe ecran.A cumpărat altă placă de bază şi tot aşa face.

pai teoretic e in burning mode

daca placa de baza cumparata e identinca si pentru acelasi display ,e ceva ciudat

ori e defecta si cea cumparata,ori nu e compatibila cu displayul,deci nu e identica

ori 12v ce ajunge pe t.con nu e ok(ar trebui vazuta si sursa alimentare)

ori displayul e defect

o poza face cat o 1000 de cuvinte

ar trebui resoftata cea originala 17mb110p ,trebuie incercat pe usb un firmware full

How to exit from burning mode?

I've take some picture from boards.  The 17MB211 is the second board what I bought.

The second board what I bought is not the same code but I bought based on serial number. (label on tv)

I've tried to change the firmware (I get from offial telefunken service), same problem.

 

How could i check the correct voltage? (how many voltage in which output)

 

thank you

Traducere:

 

Cum să ies din modul ,,de ardere,,?

Am făcut niște poze de pe panouri. 17MB211 este a doua placă pe care am cumpărat-o.

A doua placă ce am cumpărat-o nu este același cod, dar am cumpărat pe baza numărului de serie. (etichetă la televizor)

Am încercat să schimb firmware-ul (primesc de la serviciul de telefonie oficială), aceeași problemă.

 Cum aș putea verifica tensiunea corectă? (câte tensiuni şi în care ieșiri)
