That one ribbon cable at a time test is how they know which side to remove, the bad side usually has distorted display and may have horizontal lines, the other side will look fine, it may not be your particular problem tho and as stated once done it can't be undone, everything you need to know about that solution is there: https://www.badcaps.net/forum/showthread.php?t=49281

One more thing.. With my TV I am getting no difference unplugging the tcon ribbon cables... if I did indeed have to end up cutting the tabs how do I know which side I have to cut?

for the 60" you can do the same as the 70",rip the bad tabs off....
Read up on the 70" model first!!!!!!!!!

Happy New Year to all!

Brief description; I have a LC-70UQ17U. When I plug the TV in, the blue stand by light is on however when I press the power button I start getting the 5 slow 2 fast blink. Eventually I believe the TV then powers off. No picture, backlight, sound, etc. If it weren't for the green light on the main board and the standby light the tv pretty much looks dead.

I took the board out of the TV and checked the voltages and everything checks out fine. I feel I have narrowed it down to maybe some issue with the panel. The T-con and main board have been changed but same issue.

IIRC, I don't get any error when disconnecting both ribbon cables form the TCON board however I get an error when either side is plugged in.

I found a video a while ago of a guy cutting the tabs from the panel/driver board? Do you actually have to cut the tab? Does this actually work? How do I know exactly which side I need to cut? Appreciate all of your help!

Try disconnecting the pannel ribbon connectors from the T-con board, and then powering the tv on. Its possable the panel is damaged

As suggested, I unplugged the ribbon cables and powered on the TV. The backlight is on. So what's next?

hi, i have a question about this, so what does the tv does if the panel is damaged, the panel turns on or remain blank? it might be a dumb question but i am new in this. thanks

If you have a thin black line running from left to right, after tab-bond removal...you have one of two issues

a) an irreparably bad panel as the driver on the other side has failed - removal will make the whole section go bad

b) contamination/damage around where you removed the ribbon cable - make sure to clean the surface of the tab connection point and make sure no ribbon cable parts remain.

Don't know why it's upside down, horizontal line at bottom

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

Different colors

Here is what it looks like. I can get more pics

not sure what to say... again feed a known test pattern in so people can understand what they are looking at / for. Having said that, it is possible that the "compromised driver" on one side "hurt" the driver on the opposite. You need to check the tab area to ensure all the "tab sticky" has been removed... use your glasses for inspection... :-)

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

ok, so.i get a good picture everywhere but the bottom, and that thin horizontal line. its mostly black,with blue and green spots.
All right sides tabs are removed, and right flex cable is connected

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

ok... thanks for the picture. I think I can make out what is happening. I don't think it has anything to do with your tcon. What's happening is that you are disconnecting a flex cable "interconnecting" the bottom edge boards and in this case a portion of the bottom board that would normally be driving that "quarter" of the panel is now disconnected. This is "equivalent" to disconnecting the tcon cable and losing that corresponding half of the screen which then turned white in your other pictures.
As I said, I personally have not seen a 60 in and its cable interconnection but know from this forum that is a bit different. On the 70, there are edge boards along the bottom and also basically the same boards along each side. Those edge boards (side) have tab cables bonded to each side of the panel. On the 70, there are small white "ribbon" cables running between the bottom and side boards at each corner.
From the discussions on this forum, the 60 does not have side edge boards but the side tab cables that are bonded to the panel are somehow connected on a similar flex material of the tab cables... in essence it carries around and down the side somehow and eventually connects to the bottom edge board somehow. I don't recall every seeing how this happens.... but a picture of the lower corner might be useful.

Anyways, from your effort, I am pretty sure that your set has a problem on the side that you have presently disconnected resulting in the white section for reasons that I have indicated. That would mean you need to peel away the tabs along the side of the panel ... but just to be clear only the side of the panel and NOT any along the bottom.
Hope it is clear.

I still have the original tcon in the tv, if tcon is faulty, could this be the reason for the white strip??.i have another tcon on order.

If i disconnect just the left side of Flex cable i get the same picture

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

hmmm ... you are likely there although the white side "blank" is "worrisome". Can you post a picture of the back side where you disconnected the cabling... the 60 is different than the 70 so it might help to understand what you are looking at.

By the way, I don't think you are doing anything wrong. when you disconnect one side, the expected result is to get some sort of picture, usually full screen. When you disconnect the other side, you are expected to get nothing.... so you are somewhat in-line with expectations. Its the large white area that is somewhat unexpected ... BUT it really depends on where / what you disconnected as it would appear that your "disconnect point" was still involving some form of the bottom board driver, hence the white screen portion.

lastly, if you feed a known test signal ... something like smpte color bars which can be found in the special features section of some dvd disc or elsewhere (computer files), you will get a better idea of the screen's functioning in terms of potential problems elsewhere. Note, the horizontal line is probably the "tell" of a driver failure on that side.

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

OK, Now with the right "Flex" cable disconnected, i get a white strip on the right (board thats dissconnected) a thin horizontal line and a black bar at the bottom of the screen.

Sooooo just clarify .Just The Bottom Right Side tab is bad?? I would need to pull that tab,
Replace Tcon ,with all other cables and ribbons connected????

[realdealthill]

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

Ok now with just the right side "Flex" Cable between the two panel boards dissconnected , i get 75% picture

And when i dissconnect just the left side "Flex" i get no backlight or image..

What am I doing wrong here?

All Tcon cables and ribbons are connected

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

Thanks a bunch guys, I i have read alot on the 70" model. just wasnt sure if it applied to the 60"

No need to yell martino. Gezzzzzz ehhhhh.

Much appreciated Budwich

Re: Sharp AQUOS LC-60LE633U--Power light flashing 5 times fast and then 2 slow flashe

This with the right tcon cable disconnected. Same side that is all white

what happens when you do a similar thing for the other side?

oops... didn't read the previous post about this side... sorry. As suggested, look at some of the 70 in posts on dealing with side tabs. The difference in the set is that there are no side boards as the tabs run to a type of flex "board" down to the bottom boards. If you look closely at the bottom corner of each side, you should see where there is a connection to the bottom boards. You can try your "test" again keeping the tcon fully connected, but disconnect at the corner. You should get a "full picture" on your set when you disconnect the right corner.

The reason for doing the test at the corners is to isolate the problem strictly to the side tabs as opposed to a possible problem with the lower / bottom boards as there have been posts of people finding a fixable issue with the bottom boards that given similar problem appearances.
