Hi guys,
I have a Sharp Le46E820. The complaint was tv works for 5 seconds.
On a Dutch forum I read the tip to replace Q7911, Q7902 and Q7909, in fact:
SBR20A200CTFP 1X
K1A378R12PI 1X
AP6679GI 1X
I started replacing them, but after that my tv worked much shorter, only a few seconds, if it worked. What I see is backlight behind the "buttons" on front of the tv and the "chevron" (one part of the Citroen logo, lets say an upward arrow) flashing.
What I hope for: a circuit description, a good schematic diagram, or some tips how to jumper this power supply. Can it work stand alone? Or does it need feedback from the tv for proper working?
On elektrotanya there is an extremely brief schematic diagram, i will try to post it here, not something I can use. No values or component names filled in. I add it here.
For now I want to gather as much information as possible before I do an attempt.
