buna seara

am primit la reparat acest tv cu vestitul sasiu 11AK30A11 

model tv = 21V53E

stiu ca acest sasiu a fost tratat si paratratat.....am citit si eu acel forum dar nu rausesc sa ma lamuresc

deci depsre ce e vorba...porneste si se opreste normal telecomanda functioneaza normal sonor totul ok

imaginea este cea din poza

a avut un monent in care imaginea si-a revenit .....am fost plecat apoi doua ore si la o noua pornire a revenit la ceea ce se vede

integrate principale

STV2248H

MSP3410G

ST9219C7B1/MN1

BALEIAJ VERTICAL = TDA8174AW

 

am masurat electroliticii si au cazut urmatorii....devalorizati sau intrerupti

C862 , C628 , C636 , C603 , C633.

 

dupa schimbare a avut acel moment in care a functionat corect

 

tensiuni masurate

secundar = 126 volti, 13,8 volti 14.5 volti

 

tensiune alimentare integrat blaieaj vertical = 26.6 volti

 

va rog frumos o sugestie....va multumesc mult pt rabdare si intelegere

 

cu respect

Categoric spire in scurt in BDH.Trebuie scoasa de pe cinescop,si privita cu atentie in interior.Daca nu e prea distrusa(si nu cred,deoarece are momente cand functioneaza normal),se pot indeparta spirele in scurt-unele fata de altele-si se introduce intre ele foita de pvc.Cu atentie se salveaza bobina.
