TV WORKS!!!
A new T-Con has fixed the Problem and it works.... now I will mount all togetter and test again.
So I think the blown small little ceramic cap has damaged the T-CON Board....
great! :-)

Re: Sharp LC-80LE645E Flashing 2-5 :-(
If I disconnect one ribbon cable from T-Con than one side of the TV is complete white and the other side is with this dark picture without green....
If I disconnect the other ribbon cable it is the same but left and right turned.....
The voltage of T-Con is 11.9V ....
I have ordered a spare T-Con now.... we will see.....Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(

Re: Sharp LC-80LE645E Flashing 2-5 :-(
There is NEARLY no green video being supplied.... so you see a Cyan part (green/blue) and there are also some white parts.... but main parts of green is missing, but not all, it is very currious.
this would be interesting to know......
Mainboard I have two pcs here, and with both the same problem.... so I will try to get new T-CON... perhaps it got damaged because of this bad short circuit from this cap!...Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
here again some testpictures:
see information in picture name!
the picture is bad in ATV, DTV, HDMI, TV menue
the picture looks good in service menue but here I can't feed in testpictures...Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
so, I got the new ceramic capacitor... but soldering it has no change of the bad picture....
soo, the Error 2-5 problem is repaired with changing this capacitor but I have still the bad picture......
Is it better to make a new theme here according this bad picture? so I think it has nothing to do with the tabs arround the LCD.....
@budwich
I have two mainboards here and both has the same problem.....
could it be a failure T-CON??!?
I make new more pictures.....Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
no change if I am removing the left or the right corner white cable.... only if I remove both of them, but this should be normal?!....
tomorrow I got the new capacitor (but I think this will not help....)
This testpicture comes from my notebook by HDMI....
But ATV and TV Menue looks the same....
only the picture of the SERVICE Menue looks perfect.....
here I can choose also some testpictures (complete screen in each color and so on) and also this test works fine!! here I have green and all other colors...Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
yes I am missing green.... but some parts are dark white.... so there should be green in?!?
and all is darker so darkwhite parts or grey parts are black.....
it seems that complete picture has the same problem, not differents from right to the left.....
the cable between mainboard and T-Con looks fine and no change in picture if I touch it.....
hmmmm........Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
It looks like I can't write exactly what I mean.....
yes, nearly zero ohm.... I work dayly with ceramic capacitors and I know that this can't be good, also if it gets extremly hot within 2 seconds is not normal for a capacitor :-)
It is the same with the white corner cable and without....
I can't do a picture because of ERROR 2-5 and no backlight..... the TV does not work with this bad Capacitor soldered!!
If the bad capacitor is soldered the TV works only if the...Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
I have ordered one.... but I do not know the value exactly.... :-(
yes it has low resistance and if I put 12V on it, I have high current.Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
If I put back the defective capacitor (with short cirquit!) than the complete left side of the TV does not work, so this makes no sense....
This defective part is directly after the white ribbon cable comming from T-CON.
So with it the 12V are shortet and the TV gets 2-5 error.....
Yes the Main Problem with ERROR 2-5 is repaired now with removing the bad cap....
But now picture is bad... (I will send testpattern picture!)
It could be that the picture is bad because of this missing capacitor, but...Leave a comment:

hello all
The corner white cable and all the tabs are okay I think.....
I have disconnected the corner white cable on the left side and the picture was exactly the same bad as with the cable.
And I have disconnected the white cable on the right corner and here too, same bad picture.....
so now I think everything is good with the Tabs....
But why is the picture still bad?
could it be that the T-CON board is damaged???? should I get a new one here??
Or do I have to adjust...Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
I don't understand why the picture looks good in HIDDEN SETUP MENUE
and why it looks bad and so dark in the normal way? What could be wrong too?Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
attached 4 pictures of the 4 pcbs from one side of the display....
the other side is absolutely the same....
T-CON has two ribbon cables one for the right side and one for the left side....
So I think everything is good connected?????
i can feel some heat on each display driver chip at the bottom of the display tabs.... at the side tabs I can feel no heat, left and right side........Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
Dear budwich
I don't understand exactly what you mean?
so the side tabs has no electric connection with the rest if I disconnect the ribboncable in the middle.... not correct??!?
But I have soldered out this bad capacitor which I have marked in the picture above.... and now the TV works... not good, but it works.....
it works with ALL tabs connected!! (and without this cap!)
But I have no good picture, all is very dark.... do you know what here can be wrong?
only in the service...Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
sorry guys my English is bad I know... ;-)
I have news, I have picked up all the metall parts arround the LCD, now I could check all the taBs! ;-)
all of them looks good!
Problem is on the first PCB on the left side.... (see the first picture)
you see on the right side of this PCB the white ribbon cable is connected at the middle of the TV! and on the left side the kapton ribbon cable is not connected, with this situation the TV does not work.... If I disconnect the white cable it works... so it has...Leave a comment:

Re: Sharp LC-80LE645E Flashing 2-5 :-(
Dear Budwich
thanks a lot for your replay....
I will remove the ribbon on the corners to see which side it is.
I don't understand this LAST step.
What do you mean with "removing the taps" ??
Do you mean removing the ribbon cables from LCD itself? If I do this there will be pixel or line losses, not?Leave a comment:

Sharp LC-80LE645E Flashing 2-5 :-(
Dear all.
I have troubles with my Sharp TV.... it is nearly 4 years old.... (1 year after warranty) and sharp says they can't repair because of no spare parts.... so I have to try myself....
So Error 2-5 seems to be Power supply error.... but I think it is not.... I got a new (old) Power supply from E-Bay but with this I have absolutely same error.... after reading here a lot, I understand that the Error comes from TCON Board or Display.....
So I have disconnected both big ribbon cables from TCON board... and now TV starts without error and Backlights...
