Re: e701i-a3 no picture but backlights

I found mine on ebay.. there were a couple vendors selling out of california and they were 20 bucks and came in a couple days.

Re: e701i-a3 no picture but backlights



Boom, this is what I needed to hear. Went ahead and tore the right side off and a week later it's still working great! Picture looks back to normal. In the beginning I had some oddities happen, where it would look fine, and then have some odd lines (see pic), but it seems to be working fine now in the last several days. Just want to say thanks again for the help on this place! We'll see how long I prolonged this TV's final end.

Re: e701i-a3 no picture but backlights

Ok, baby steps.. so I plugged in the left cable from the output on the tconn board, and I disconnected the connector at 2R and I have what you see here:



I didn't try the reverse because that's what killed my tconn before (just want to be 100% sure it's the right side before I pull em off still).

Then I pulled off both 2R and 2L and I get this (just leaving vertical driver boards connected) and connected both outputs from tconn and I get this:



This is the screen...

Re: e701i-a3 no picture but backlights



Interesting... So the question comes to mind why not just disconnect the ribbon right at the outlet of the tconn board (yellow line)? Or is there something extra happening by letting power run all the way down the blue line till it gets to 2r?Can I still damage the tconn by doing this?

And disconnecting connector 2r should at least let me keep all 4 connections at the tconn plugged in without worry of frying the board I assume?

Think I'm getting there.. just gotta try it I guess....

Re: e701i-a3 no picture but backlights



Interesting.. why does the corner matter over the output of the Tconn board itself? Also in my pic would that be disconnecting it at 2R or 3R? does it matter which corner connector is disconnected between 2 and 3? I assume even if you disconnect corner board there's still risk of frying the Tconn board when connected to all outputs if something is wrong with the drivers? Is there a way the risk to the Tconn can be minimized? Pic for reference of connector points:

Guess I can't edit posts, just thought I'd further clarify pic:

General overview of back of TV. Upside down as you can see, hopefully labels can help. From Tconn ribbons (yellow) to connector (1R/L) then from board on the bottom (blue) to corner ribbon (pink) to side drivers (green). Connectors are shown at arrow locations 1, 2, and 3. Annotations are labeled as looking at the back of the TV upright:

Re: e701i-a3 no picture but backlights

I've had similar issues as everyone and I've gone through a couple Tconns now so I want to make sure I don't screw this up again. Standard scenario as the rest - black screen, backlight works, audio works. So replaced Tconn first time hoping that would do it, plugged everything back in and died again within 2 minutes of use.

Tried new replacement Tconn and checked output voltage seemed good. After reading more, I plugged one output ribbon in at a time from the Tconn, choosing left side to connect first. Turn on and picture shows...
