Re: Sharp LC-70LE857U - Wont power on
I was asking if the coloration issue was related to the Tab driver issue. I will peel the tabs when I have a few moments to take the front bezel off. So I was trying to get an opinion. Seeing as how I don't do this work every day, I like to try to be ultra cautious. That's what I was waiting for....

Re: Sharp LC-70LE857U - Wont power on
Anyone have any suggestions about this color issue? Seems to fade from red on the left to green on the right. Is this still because I haven't peeled the bonded tabs? or could this be a TCON issue too?
Thanks!...Leave a comment:

Re: Sharp LC-70LE857U - Wont power on
I should also mention that at current state, the left side drivers are disconnected, but I have not peeled the bonds from the screen. I am getting from reading that the darkness may be from the tabs not being peeled, but how about the trails I am seeing? Is that also from the tabs not being peeled off of the LCD? That will have to be my next step....Leave a comment:

So I did a factory init. And the TV boots now, but the color is REALLY wacked out. TONS of red, and 3 small horizontal stripes across the bottom of the screen. I took a picture, I just have see if this post of the pic works...

How do I do this without having the remote? I didn't see that anywhere yet? Maybe I overlooked it.
Thanks again!...Leave a comment:

Re: Sharp LC-70LE857U - Wont power on
Ok, so here goes. I have all the TCON cables connected, and disconnected the left (facing the back of the TV) corner cable, and nothing, then I reconnected it, and disconnected the right corner cable, and I get the sharp logo, and I see the K when I put it into service mode. Problem is, when I take it out of maintenance mode, it wont boot. I get the 1/1 blink sequence telling me there is a lamp error. So from what I read, it seems that the right driver will need to be peeled off. Is this what is keeping it from booting up normally...Leave a comment:

Re: Sharp LC-70LE857U - Wont power on
ok, so I missed one of the 4 flat ZIF cables on the TCON board, so I made sure that was seated and making a good connection... then I disconnected both of the corner cables. I still get the One long blink, and one short blink. So I did the Volume - & Input while plugging it in. Took a few seconds.. but the entire backlight lit up. Saw some vertical red stripes at first, but then it looked like a complete all lit backlight.. all nice and bright. The problem is, when I turn it off, and hit the power.. for a moment, I see a few vertical red...Leave a comment:

Sharp LC-70LE857U - Wont power on
Greetings folks! I have the Sharp Aquos 70" TV which I got from a friend of mine. When he had it, it was giving him the 2 slow flash, and then 5 fast flash error. When I got it to my house, it was giving me the one slow and one fast flash sequence. I have been reading this forum for the last 8 hours skimming for any help that would allow me to troubleshoot. I am REAL new to this, so the learning curve is gigantic. The back panel is off, and I have already tried the lamp error reset, and for a very long time, no matter what I tried, it was as if the buttons I was pushing weren't registering.... -

Hi there, My name is George and I am a "computer guy" by trade. Since TVs became more like Computers, I figured I would try my hand at fixing TV or two about 2 years ago. So far, I have gone as far as replacing power boards in my Samsung 65" led fired DLP TV (twice) Had a friend of mine solder a couple of new caps into the power board in my Lg 32" TV then reinstalled that board (not great at soldering), and now, I started tinkering with a Sharp Aquos 70" which is going to be the biggest challenge for...Leave a comment:
