Sharp LC-70C7500U- horizontal line

[TonyG_]

Sorry if this was answered somewhere else in the forum. I had a horizontal line, about 3/4" wide appear on my 2013 Sharp panel. It starts about 1/3 of the way down from the top left and spans across the screen from left to right, gradually fading before it hits the right side of the panel. The TV is past warranty. Additionally, a recent development is the 2 long blink, 5 short blink problem. Lots of turning off then on finally gets the panel to work, albeit with the horizontal line. Are these two problems related? I've attached a picture of the line. Thanks in advance for any help.

your problem is a "standard panel fault". it is not fixable but the set can be saved. lots of posts with similar sets and good saves. search and read as the save is a one way path requiing the removal of tabs along the failed side.

did u buy this set initially ?? looks like the left side tabs have already been removed. your symptom looks like the aftermath of a bad tab removal job

That's not the result of a removed gate. If one side has been removed and then when the other side goes to fail it will fail with a bunch of vertical streaking lines As the panel has no way to address horizontal gate driving anymore.

Had this happen to a 70 inch Sony already. That's the only TV that I know that has failed. This is the one that it is listed on my YouTube channel

I purchased the set new from BJs in August of 2013

as suggested Freakaftr8, your problem isn't from a removal... you / it hasn't got there yet... :-)

Anyways, when you look at the tabs along the side in question, you may / will see that the one in "proximity" to the line has an issue such as heat markings or hot to touch compared to others. As suggested, read up on a few threads to get an idea of what you are up against and decide on your best path forward. Personally, the 70 set that I saved for my neighbor is now almost 2.5 years older since the save and the neighbor still smiles every time I see him.

Freakaftr8 and budwich... Thanks for the pointers on what to look for when I open the set.
