I haven't cracked it open yet. Does this look like a tab bonding issue?

Re: Sharp lc-70le660u....is it a tab issue?
That's an interesting symptom! Believe it or not I have a gentleman wants me to look at his 90" sharp that is doing the same thing! This is the 2nd time I've seen this now.
I'm putting my bets on yes it is a tab driver problem. I do not see how a t con can cause this problem as it does have a uniform picture all the way across the bottom side. The side tab drivers take that signal and serial it up all the way across the panel from bottom to top. I believe if one of those gets garbled up, It's going to take that signal and pass it on to the next carrier package (side tab).Did I leave the soldering iron on?

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... -
Hello everyone,
I recently got a model Sharp TV, and I've noticed that the green power LED is flashing without any specific pattern. Additionally, there appears to be no voltage coming from the power board. I haven't observed any leaking or bulging capacitors, although the top of the larger capacitor doesn't seem to be perfectly flush with the jacket—if that makes sense.
Has anyone dealt with this issue before? -
Hello,
I bought Sharp LC-47SB57UT 6 years ago. I had to have a vhf antenna to pick up one local station(koco channel 5 OKC). It has worked great up until a week ago. Sometimes I couldn't get channel 5, now I can't receive it at all. I can hook up a digital convertor box I have from another tv and can receive channel 5.
I think the antenna and cable is ok. I doubt that this would be the tuner board or possibly something else.
Any ideas where I should start?10-24-2024, 03:11 AM -
Dear,
I can not pinpoint the following problem on my Sharp TV LC70LE747E.
While the left side of the screen is not affected at all the right side of the screen gradually fades to a kind of dark. I can best describe this darkness like a totally worn out CRT display or a gamma correction totally out of range. This darkness flickers like a flame, a dark one tough.
Sometimes when I restart the TV it disappears for a while.
The problem worsened over time the last few months.
I've replaced the t-con module without success. The problem remains.

Hello Everyone,
This is my first post so I will try to be as precise as possible without making this post too long winded. Unfortunately I don't have pictures of the original problem but I included images of the TV internals.
I have a Sharp 70LE660U. The problem started a few months ago with the bottom row looking out of sync and was dark on the left side and then fading to transparent on the right side. Shortly after, a dark cloud appeared in the center of the screen. The dark cloud started small and shaded but the image was visible. It also affected the menu area....
