Boot loop? QN70Q6DTAFXZA
oldturkey03,
You were spectacular with your expertease on ealier problem of mine, hoping you might help with an answer to my question and sumation of a problem (s) which have been questioned several times before on the forum.
Driver board is made up of central ribbon and a left and a right sub ribbon made up of 2 more driver boards on each sub ribbon. By disconnecting ANY of, or all driver boards , boot loop stops and back lights stay illuminated. You mentioned on an ealier post that these systems might have a shorted capacitor. By removing any of the subs and aquiring a steady back light system, might you suggest that the main problem might be centered in the center board, and any additional load creates the back light problem.
Your input also in the question of: Can caps be tested in circuit?
And again, thank you for input to my ealier problem.
PS, no image what so ever!
Update (04/29/24)
IF...... I were to install a main board from a 65" Samsung with same connecters, in place of exsisting main board, and any visuals were to show up on screen, might you suggest that the main board in the 70" is faulty?
Es esta una buena pregunta?
