Мои познания в ремонте данного вида техники: Любитель Наличие схемы: no Hi friends, some time ago I was given a Nordmende ND55KS5300J TV with a faulty main board... finally on ebay I found an apparently identical one "TPD.MT9602.PC823(T)" practically a three in one 4K motherboard mounted on several Chinese TVs... In short I bought it hoping it was compatible with my panel; the guy who sold it said he got it from a jvc 55" with a broken panel, but when I turn it on the Akai logo comes out... Anyway, now I find the screen divided into 2 identical parts (as shown in the photo). Apart from this not insignificant inconvenience, the rest seems to work perfectly... Do you think that if I could access the Service Menu (Factory Menu) I could solve the problem? I tried hundreds of codes found online such as: MENU 1,1,4,7 but nothing, none of them allow me to access this damned secret Menu. Could anyone of you suggest something? I await your suggestions, thanks in advance!
