Re: Sharp Aquos LC-70C6600U UNBELEIVABLE SCORE!!!!!!!!!!
HOLY OLD THREAD REVIVAL BATMAN!!!!!
So I dug this one out of storage for more diagnosing. After detaching the interconnect cable on the right source driver board from the right center SDB the TV turned on and stayed on. After a bit of component checking I found another identical SDB in my stash and compared SMD component readings one to the other and all were close. I tried the scotch tape trick over half the contacts on the interconnect cable from the right center SDB to the right SDB and got a change of state, the TV stayed on!
I continued to move the tape further and further to the right, and when I got to the point 4 of the contacts were insulated the TV faulted. Cover 5 of the contacts and it stays running with a full picture and seems to turn on and off just fine now!
There are 5 traces in-circuit from the interconnect to the taped contacts. Either there's a bad SMD component at the end of the SDB....or an LCD problem.
I tossed up some pix here for you to see. Anyone want to take a guess if the SMDs in-circuit are bad or the LCD itself?Attached FilesThey call me......."threadkiller"

Looks like we have a problem still. Any ideas? Side tabs?

Re: Sharp Aquos LC-70C6600U UNBELEIVABLE SCORE!!!!!!!!!!
You definitely have a side tab problem but you may still have more beyond that.
Have you not yet removed the tabs on this set ?Comment

Re: Sharp Aquos LC-70C6600U UNBELEIVABLE SCORE!!!!!!!!!!
the "tape cutoff" method of blocking signals at the tcon usually does not work when the set has side tabs. Do the "disconnect the small corner cable" test to determine what's up with the panel.Comment

Re: Sharp Aquos LC-70C6600U UNBELEIVABLE SCORE!!!!!!!!!!
I did last night at 1am. The picture is now mostly good but has some light horizontal lines on the lower left side of the screen. These only show with certain colors on the screen. Those lines may be a misaligned interconnect or FFC from t-con to source driver boards too, I still have to check that. At first, after about 10min of use the screen would go "haywire" until I removed the glue/bonding residue where the side tabs were attached.
There isn't a corner cable upon this model. I've used the cutoff method on screens with side tabs and it seems to work on most TVs.They call me......."threadkiller"Comment

Re: Sharp Aquos LC-70C6600U UNBELEIVABLE SCORE!!!!!!!!!!
Well guys, this TV is headed for the parts bin. I re-set all the FFCs and interconnects, turned it on and the screen went glitchy within 2 minutes. I turned it off then back on, the screen straightened out and stayed OK but the GDIC second up on the right side tab is running very hot compared to the others and the tab itself appears to be blistering under the IC.
I really didn't want to part this TV out but it's still a winner, and a pretty big winner compared to what I paid for it!
Thanks for the help on this one folks, I appreciate it.They call me......."threadkiller"Comment

I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp... -
Hello!
I'm a few days old into this TV screens repair universe so please bear with me.
Recently, and all of a sudden my 40” 4K Sharp Aquos LCD TV turned on with colors all smudged in some places on the screen that remain like that even without any kind of video source. I do have image but the colors are smudged/tinted/ washed out in patches as per defects. This to me looks similar to burn in but I’m shore this is not an OLED.
- I did the classic unplug and hold power button to discharge the caps but it didn't help.
- I did a factory reset as well... -

This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors
I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using
I am comparing them to a brand new one that I installed
The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well
I going to let it run for several days before I remount back on the wall next to the... -
I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it's image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...
