multumesc pt raspuns dl iuliantv si dl gaguady,am banuit ca este vb de tk uzat si de aceea,am apelat la metoda descrisa in caietul service nr6,fara succes insa,cat priveste c-urile,le-am verificat si inlocuit unde mi s-au parut suspecte.Voi face rost de o telecomanda si voi incerca sa intru in M.S ,dar asta peste o luna,deoarece atunci merg la serviciu si ma ocup de el.Multumesc si va tin la curent daca il rezolv.
