My SHARP LC-70LE857U that I repaired 2.5 years ago is still working great. There was no way I was selling this "best find" !Last edited by ajshoe; 03-07-2018, 05:33 AM.Comment

Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
I just picked up a FREE 70" 70LE757U yesterday. I was getting the 2 slow, 5 fast blinks. I unplugged the 2 ribbons from the T-Con that controlled the right side, and the TV powered on, but obviously with only half the screen. Every thing I found online said the panel was dead....then I found this thread!
I figured, what the heck..I'll give it a try. So I removed that side of the bezel to get to where the ribbon attaches to the panel, and removed those ribbons. The right side/top ribbon showed a burnt chip. I removed all the ribbons and the TV powered on and looks great!
Thanks for all the info, and great save!Comment

Hey Guys, I posted in the other thread, but this one appears to have more life to it, so I'll post here as well, just in case..
Looks like the Right side is def. the culprit... Please see below, confirmation would be greatly appreciated, but I'm going to take the leap one way or the other in the next hour or so.. I'm running on borrowed time, my in-laws are returning home tonight and the TV is on their bed.. Don't think they'll want to sleep with it! hahah
TIA!

Yes it appears the right side has failed.Did I leave the soldering iron on?Comment

Thanks for getting back to me! I took the leap and it's working! I can't thank you enough for posting these through walk throughs for everybody's benefit. You have saved me at least $1k! If you're ever in the Redneck Riviera, I'm buying you a beer!
Thanks Much!

This thread was amazing. Thanks to everyone here. I fixed a 70" panel last night by removing the left side ribbon cables and all works perfectly!Comment

Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
Just a quick question. I have the back off of my 70-LE632U and my TCON has only two ribbon cables connected to it. No matter if I remove the left, right or both of the ribbon cables, I get the dreaded 2-5. I am betting that means this fix is not going to work for me correct?Comment

Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
you need to do more checking such as measuring voltages at the tcon, along with those printed on the power supply card to verify that they are producing the correct numbers. Go from there on what you find.Comment

Quick question...
Is it possible to remove the driver tabs on BOTH sides of a Sharp LED (LC-60LE650U) without trashing the display?
Thanks!

NO.... the side drivers provide a signal path to the screen for the image... you need at least one side "full" of drivers to have an image.Comment

Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
Hi,
This weekend I saw some lines come across the screen, shut it down then restarted it came back up. But then it started blinking 2 long an 5 fast flashed. I spoke to Shop Jimmy he told me it' the main board but from what I'm reading on this post not sure. My screen is in perfect condition no physical damage at all. I did try the volume/up yada yada to reset and nothing. I have te LC_70LE857U model. Any suggestions greatly appreciated, can't believe it failed after 4 yrs or so. !!! thxsComment

third anniversary for the original set that started this thread. Neighbor is still smiling and can't believe his eyes and his happy wife. He wants me to fix his cracked screen samsung S8 phone (wrap around screen). That is probably more difficult than the sharp save... :-)Comment

Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
So happy that I stumbled across this thread and would love to save an LC70UD27U 4K set that has the 2-5 blink code. I am able to get an image on screen if I unplug one of the 4 ribbons from the t con so I know which side is affected. Has anyone tried the tab removal on a 4K set yet?Comment

Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
I think you will likely find a few threads that use the "tab removal" method on 4k... the tabs don't determine the resolution so if indeed the only way you can get you set to show a picture is by disconnecting a tcon cable, then you perhaps are heading in the tab removal direction BUT.... there is a possibility that its not a tab issue but a smd component issue which is different. Does your set have side edge boards similar to the bottom one OR just tabs along the side of the set?Comment

Re: Sharp LC-70LE757U Flashing 2-5 :-( can it be saved economically?
looks like i found the right thread! greetings guys.
The culprit: LC-70LE757U
I haven't read all 12 pages of this thread yet but does this look like anything familiar to you guys who've been working on this model for a while now? Just 2 thin solid lines toward the bottom of the screen shown in the attached pics. No flickering, no power on/off issues, no blinking lights. It will stay on and play all day like this. Just wondering what I can do to get rid of these lines. Thanks in advance!Attached Filesif you find these attachements useful please consider making a small donation to the site

I have a Sharp Aquos LC-80LE757U that randomly made a loud popping noise when when watching TV one day. We found that the fuse blew and the thermistor. We ended up replacing the entire power supply board and have also replaced the TCON board. Now as soon as I plug the TV in it lights up and has the Sharp logo flashing on and off of the screen. If I unplug the ribbon cable from the TCON board to the main board I get the 2 long 5 short error code. Any ideas on where to go from here? We've tried resetting it but nothing has worked. If we plug it in and let it cycle through the flashing of the Sharp... -
Hey guys,
I have a SHARP LC-60LE640X TV that has suddenly developed an intermittent fault of flashing white noise patches (appears like an Analog tuner off signal) and then totally dropping out.
This model I believe is also known as LC-60LE600U or LC-60LE640U in other regions.
FYI, a long time ago I was a component level repair tech for all consumer electronics and IT equipment.
I'm a bit rusty but still have ability to dig right down.
I measured all power supply lines and checked them for AC ripple voltage. Noting any lines that exceeded about... -
Hey guys! It has been awhile since I've been on here. I hope everyone is doing well. I just picked up this Sharp lc-65ub30u. It plays but the screen is flashing on and off. Other than that i seems to be a great tv. Any ideas what the problem might be? I haven't pulled the back off yet. I thought I would get some opinions first. Thanks in advance for any help you can offer.

As the Elitebooks (820, 840 all gens) only show flashing Power LED and flashing CapsLock (continuously) + a very soft "ticking" noise near the DC Jack,
I wonder if re-flashing the BIOS might be of any use here.
As far as I understood, steady flashing either means insufficient power or a CPU/GPU/Motherboard issue. I use the original 65watt power supply.
There are so many threads out there, but most of the solutions involve flashing codes, which I dont have or claim that you MUST use the original power supply, do a hard reset, reseat the RAM, clean the RAM,... -
Hello again! I have come back for some wisdom and hopefully for some guidance with this problem I'm having. The TV is a 4k 55" Sharp LC-55p6050u and the problem is every other line of the bottom 32 lines flickers out, comes mostly back, then flickers out again, and repeats this continually. The lines on the bottom right of the screen go out completely while the lines on the bottom left are affected so slightly that it's almost impossible to see it. There is a gradual gradient from appearing almost perfectly fine on the bottom left, to an obvious problem on the bottom right.
