Re: Sharp Aquos LC-70LE755U - 2/5 Blink Pattern
It worked! I had removed the corner cable that had given me half a picture (right corner cable as viewed from the back of the set) and continued to remove the tab drivers on the same side. For anyone experiencing the same issue and wanting to remove these tab drivers, but unsure of how to remove these side tab drivers, I'll explain best I can on removing these. With the back cover off and the back of the set exposed I continued to remove the bezel which frames the front of the screen. I only removed the top and side screws. Removing...

Re: SHARP LC-70LE550U - side driver issue?
It worked! Thanks again budwich! For anyone experiencing the same issue, but unsure of how to remove these side tab drivers, I'll explain best I can on removing these. With the back cover off and the back of the set exposed I continued to remove the bezel which frames the front of the screen. I only removed the top and side screws. Removing only the top and side had given me enough room to remove the tabs on my particular set (LC-70LE755U). Working from top to bottom I would grab each tab and peel it forward towards the front of the set....Leave a comment:

Re: SHARP LC-70LE550U - side driver issue?
Thanks budwich! I wasn't looking into investing a lot of time or money on the set. The living room TV has already been replaced with a 75" Sony and I'm only trying to fix it for my shops break room. I'll be a hero with the guys if this works
I'll post whether or not it works once I've removed the tabs. Thanks again!

Re: SHARP LC-70LE550U - side driver issue?
You are correct in assuming that I reversed the corner cable removed and got no picture w/ the 2/5 blink pattern.
I did unclip the board to view the chips, and those are what I was inspecting in particular. None appeared to be burnt.Leave a comment:

Re: SHARP LC-70LE550U - side driver issue?
I am having a similar issue. Removed the bottom right corner ribbon cable (as viewed from behind). Left side of the picture appears bad as viewed from front of set & same side as disconnected corner ribbon cable. Below are images of the tv with the test source image on the TV and the original image I downloaded of said test source. None of the tabs/ tab drivers appeared to be burnt, but I have not felt to see if any are hot. How long should the set be on before these tabs/ tab drivers heat up enough for a notable difference?...Leave a comment:

Re: Sharp Aquos LC-70LE755U - 2/5 Blink Pattern
I tried disconnecting the left corner cable (as viewed from the back of the set). Screen is off with 2/5 blink pattern. Is there any point to inspecting the tabs/ tab drivers on this side?Leave a comment:

Re: Sharp Aquos LC-70LE755U - 2/5 Blink Pattern
Copy that. I checked for bad tabs/ tab drivers and didn't see any that looked burned out as in the thread I linked to above
I will reverse the corner cable disconnect test to confirm the set does not come on. Below is the test pattern on the screen in its current state. Please notice there is black bars to either side of the test pattern since I could not get it to fit to screen. I have also included an image of the test pattern image I used. Hope this helps. Thanks again!...

Re: Sharp Aquos LC-70LE755U - 2/5 Blink Pattern
budwich, thanks for your help. I disconnected the right corner cable (as viewed from the back) and the screen came on! I've posted a picture below of what the screen now looks like. I believe I can solve the issue by following the steps in this thread:[URL="https://www.badcaps.net/forum/showthread.php?t=50587&highlight=sharp+aquos"]https://www.badcaps.net/forum/showthread.php?t=50587&highlight=sharp+aquos[/URL]
Seems to be the "classinc tab issue." I will now begin to look for the culprit (bad tab/...Leave a comment:

Sharp Aquos LC-70LE755U - 2/5 Blink Pattern
TV is approx 2 years old. Used frequently until 2/5 blink pattern of death (2-5 error code) appeared. I disconnected all 4 ribbon cables and the backlight comes on with the 2/5 blink pattern replaced with a steady glow. I've read on this forum that this means the panel is bad, but if the 2/5 blink pattern persists the T-Con needs to be replaced. Is this correct? What should be my next step?... -
Re: sharp lc-c5255u only blink codes no picture
I had the same issue (2-5 error) and I did the "Channel Down & Volume Up," reset and now my light no longer flashes. It just stays on and it doesn't appear that the backlight is coming on. Any thoughts or ideas before I crack this baby open and start disconnecting ribbon cables?Leave a comment:
