Re: e701i-a3 no picture but backlights

He pulled them off and once off they don't go back on.

That's what I figured, but isn't the picture now showing the set working?

Or am I confused?

Here you all go! This is a repair on a Sony KDL-70r 550a model that someone brought to me for repair. This is using the failure -prone Sharp 70 inch LCD panel. The only difference between this panel and the Vizio model which also uses the Sharp 70 inch panel is this model is 3D. It doesn't play any difference on the design of the panel though. This was the second of this model TV that somebody had brought to me in a week. The first one that I tried to repair had vertical tab failure so it was inevitable useless. This one however had the same symptoms as that one shutting down with with a 5 blink code but as soon as I started unplugging one or the other side of the panel from the t-con board I knew exactly what I was in for and this is the result. After this video I have fixed another Sony of the same model for another customer and another Vizio. The other Sony was the left side driver boards instead of the right and the Visio I just repaired was the right side driver boards not the left so with this information either side can go bad so don't jump to conclusions right away before you do testing. The lucky thing about the Sonys and Sharp models is that they're OCP shut down doesn't destroy the t-con board like the Vizio does so it helps in the determining factors of trying to pinpoint your diagnosis without having an array of t-con boards on hand to get to your diagnosis like the Vizio. Unless you're handy with soldering to have an array of transistors ready to replace the original coxa that goes bad, you would have to be quick with the power cord if you don't get a picture right away on the Vizio and sometimes when you're lucky you will not blow up the tcon board by unplugging it before it does imminent failure to the COXA transistor on the board.

Freak, any chance you'd change this video to being a non-private video? I'm working on a set and would like to watch it. I've tried everything and still have a blank screen with backlights. all components test fine but I see that someone in earlier posts was talking about a "red cap" and seeing 15.3V there. I don't see that but the transistors, other caps, and other spots have the correct voltage. You never really mentioned this "red cap" (mines orange like your photos show). Any idea of what could cause 0v on this orange capacitor?
