sharp LC-60LE847U / 857U panel swap?

[tucocaps]

Hello Everyone,

I've actually got a number of these Sharp sets of similar size, but slightly different models. The problem is most have the dreaded 2 long 5 short blink panel failure error code. This is expected, since they are all damaged panels. However, I haven't been able to "bypass" the blink error by unplugging any combination of the four ribbons attaching the tcon to the panel.

Since I have one LC-60LE857U that is/was working, I was beginning to wonder if I could simply connected all the boards from another set to that chassis, and the panel, in order to test for purposes of salvaging the boards.

These two seem similar, and pictured are the two model tags for the panels. Are they the same, or is mostly ever panel unique on sets like these?

Anyone have any idea on this? I'm down to just a few sets now, and 3 are the "5 flash/Panel". All model LC-60LE847U. I found a compatibility chart in two different Sharp SM's, but they don't exactly line up to what I need. Not sure if I could just try, or if an incorrect panel runs risk of burning out the TCON or power?

Incorrect T-con runs the risk of damaging the pane more than anything. That said, if the LVDS to the T-con is OK, you could leave the original T-con in and test everything else as you would otherwise. I would not advise testing the T-con.

Interesting point on the TCON "reuse" for testing. I did swap a TCON on one of the sets, but according to Sharp data, that TCON was for the same panel as the other TCON.

I gather from what you are saying that I could possibly plug the main and power into the TCON attached to the proper panel ( that happens to work). However, in that case I'd be connecting the mainboard to an unexpected TCON. They all seem similar on the outside with the LVDS, etc. but would that run the risk of damaging the main? AKA hooking up the incorrect TCON?

How different are we talking?
You can check the pin out and see if it is similar, i.e. right pins grounded, right pins power.
There is always a risk with unknown hardware - but it is unlikely that Sharp would have completely changed LVDS pin out for such a minor revision. Not impossible, but unlikely.

Tom,

Is there a way to check it with a data sheet of some sort? The TCON pictured is the one I'd like to use to test the boards off the LC-60LE847U models. This TCON currently attached to a partially damaged panel, is an LC-60C7500U. It does use a different power board than the LE847U. These are all 60 inch panels, and then I have one 70.

I can also use the TCON/panel from an LC-60LE857U.

I can't see any difference between those boards.
I think you will be OK.
Unless you could find a schematic I don't think you can be certain.
The boards seem to have the same part number though.
