Re: Sharp Aquos LC-70LE650U
Can't tell where it came from but I still had the narrow circuit boards connected to the bottom corner ribbon cable. I removed the narrow boards and covered the end of the ribbon cable with some tape. Hopefully this will work...
Once I sat down to look at the gates I saw that the one at the bottom left corner was crispy. Take a look.
Notice the corner, it's discolored and damaged too.
Thank you for helping me with this, I feel the other TV is going to need the same treatment...

Re: Sharp Aquos LC-70LE650U
After removing the tabs and turning on the TV, it started to smoke on the bottom left corner behind the panel.
I immediately turned it off and after a few minutes passed I turned it back on. No smoke this time.
Looks like it is working at this point....Last edited by b43n70n; 09-11-2018, 08:46 AM.Leave a comment:

Re: Sharp Aquos LC-70LE650U
I tested several times covering up some pins on the tcon connector but didn't have any success with that and I am afraid of damaging that connector. Looks like the only thing left to do is surgery, right? Do they all need to be cut or should I start from the bottom?
The hair on the back of my neck stands on end just thinking about this surgery.Leave a comment:

Re: Sharp Aquos LC-70LE650U
I don't believe I see any silk screening on the tcon board where those connections are......Last edited by b43n70n; 09-10-2018, 02:31 PM.Leave a comment:

Re: Sharp Aquos LC-70LE650U
Sorry for the poor choice of words. I have been working with electrons all my life, just not with 70 inch monitors although I've replaced my share of caps in Dell monitors.
I have attached an image of the screen after disconnecting the ribbon cable on the bottom left side of the screen...
The blue at the top left of the screen is a reflection of a monitor, I tried to turn it to reduce the amount of reflections but that was missed.Leave a comment:

Re: Sharp Aquos LC-70LE650U
Looks like I jumped the gun a little. After injecting a signal there are lines on the left side. Is this where I have to rip off the brown tabs?Leave a comment:

Re: Sharp Aquos LC-70LE650U
I took off the left side metal bar and disconnected the ribbon cable on the left side and now the TV is working properly without having to cut anything off.
Is this really all there is to it?Leave a comment:

Re: Sharp Aquos LC-70LE650U
I was able to get to the service menu with the blue text. There were 1-27 pages of information as I pressed the channel up and down buttons. I could change some of the items with the volume up and down. But I did not see anything about working hours.
I disconnected the tcon connectors one at a time and the problem persisted with the left side (while looking at front of TV) connected but went away with the right side connected. So with the left side disconnected there were not flickering lines.Leave a comment:

Re: Sharp Aquos LC-70LE650U
These TV's are mounted high enough that they do not get touched by anybody. They are both turned on only during events and then shut off the rest of the time. I would estimate they are on less than 10 hours a week and that is a high estimate. One thing I regret not doing is using some kind of line conditioner since we have so many electrical storms here in Florida.
As for the secret service menu. I went through all 27 pages and did not see a "total hour counter". Unless I was in the wrong service menu...
I have...Leave a comment:

Re: Storing extension cords (suggestion)
I have had extreme front yard displays and the best way I have found for XMAS lights is to roll them up like a ball of yarn and place each ball in a plastic grocery bag. This gives you an easy way to label them and also transport them around and drop them into storage containers. The next year just grab the bags by the handles and lift them out....Leave a comment:

Have two of these TV's, one on either side of the room. One of them started acting up with the screen flickering. After disconnecting all inputs and going to the menu screen it was still flickering. Here is a video of what I am seeing...

I swapped the TV from the other side of the room over to this side and within the hour the second TV started doing the same thing.
I have read through many threads here and have not seen this exact problem but I have tried resetting the... -
Re: New Members - please post your introductions here
Hi, I come here for knowledge or your people from a planet far far away where everybody fixes things instead of throwing them away. I have been repairing to the component level since the beginning of time. All that is needed is a little research and that is what brings me to your fine establishment of a website. Thank you for providing a resource to those of us who still have the courage and determination to not fall into the throwaway culture.Leave a comment:
