vertical line on 42" Sharp Aquos

post #1 of 68
Thread Starter 
Hello everyone, last year i bought a 42" Aquos. I have loved it so far but have noticed a dark vertical line right down the center of the picture. It is hard to see unless it has a blue or similar color background. I don't get a chance to read through all the posts very often and don't know if the Aquos has an issue with this.

Anyone else have this problem and what is it?

THX, Jerry

I'm trying to figure out if this is a joke post/account. Whatever the case, it's pretty funny. In all seriousness, I doubt you could happen into a single Sharp related topic on this board without encountering banding discussions.

No joke here. I thought banding was a totally different thing.

Isn't banding moving horozontal bands? This is just one very thin vertical line right down the center that stays put.

Nope it's not banding. Besides this banding thing is overblown to some extent, with folks looking for it and it actually not problem. But yours sounds more ominous. Does line show up no matter what the source you're watching? Sounds like you have a line of pixels (transistors) which are dead or dying. Replacement of set likely. Be prepared to send in digital camera photos.

Hello,
i have a 42inch unit also and this has a dark vertical line which extends from the top of the picture to approx 2/3 down. it is really prominent on blue or yellow backgrounds.
i have discussed this with an engineer friend of mine. it has been like this from day one.
he believes it is caused by a small gap between the two backlight plates behind the screen pixel layer. it is of course non repairable and will probably require a new TV. i am presently in discussion with sharp over this, for although it is not a major problem, i know its there and it's really bugs the hell out of me. the backlight plates come in a matched pair, some large screens have four of these plates, if the assembly has not been precisely executed then a gap between the plates causes a dead spot of light, so a dark patch appears.
if it is at the join then this will appear as a line vertical or horizontal depending upon which face is incorrectly mounted. if and when i get my reply from sharp i will let you know the outcome. till then keep watching and keep enjoying. Hi Def is here to stay. hooray.

I bought my Aquos over a year ago (it was the LC-42D64U model I think) and it has the exact same problem, the dark vertical line about 1/4" wide, but it goes all the way down to the bottom of the screen. The TV was fine up until about 4 months ago, or at least I never noticed it until then.

Nemesis20000_0, I'd be interested to know if you ever resolved this with Sharp and what they said caused it.
post #7 of 68
this seems to be pretty common problem from what I have read on this model. Just today I had BB come out and take a look at mine. They said they would need to replace the panel. To replace the panel it was going to be $2400. I paid only $1800. BUT, I also purchased their PSP plan, so tonight I returned it and got the new 40" Samsung. I purchased my Sharp in Dec. of 06 and noticed the line shortly after (most noticeable to me with scenes with gray), I knew since I had the PSP plan that I could get it replaced whenever, so I have just been waiting for the right time.

Wow this sounds exactly like my problem. I didn't start noticing it until about a month ago. The line is right down the middle and is not always noticeable except when it's a lighter screen and the colors are similar around it (i.e. a uniform shade). It is however really annoying me now.

Unfortunately I bought my LC-42D64U in Dec 06 so the warranty is up, so I haven't bothered calling them yet. Anyone else have any luck with in terms of dealing with Sharp?

I had the exact same problem with m 42d62u that i bought in jan 07. I called the first week of march 08 and they extend my warranty and agreed to replace the tv. They sent me a refurbed 42d64u which came with problems. They are in the process of replacing that with a new 46d82u. So you should definitely call sharp and they may help you like they did in my case.


here is what my 42d62u looked like

Your response is exactly what I was hoping to hear. The image you posted is identical to what I've been experiencing, I'll be sure to give them a call then. I really appreciate the help, thanks chef jer!

Dull Electronics is more like it. Than again even that sounds too catchy for a company selling yesterdays recycled gadgets.

I have a question for all you cable fans,
How is it that, the cable company comes out 4 times, tests the lines, the signal strength, picture resolution, etc... And says everything is better than expected.
A month or two goes by and a 5th tech discovers that there the two cables in the ground were cut almost in half this whole time. Which would explain the crapy picture and the reason why we canceled our HD service. He repairs the cables...
Now the picture is grainy, static, noisey, and has horizontal lines cascading through it???? How could it have gotten worse after the cables had been repaired???

Same problem here with same 42" sharp lcd model. I just noticed it this week watching golf. Seems to only be visible when there is a uniform color on most of the TV, like lots of grass on a golf course. I am calling the warranty company through Best Buy where we purchased it to figure out what the deal is going to be. I would like to avoid anything refurbished or of lesser quality.
post #14 of 68
I bought my 42D62 in Nov 2006 and started seeing the grey line down the center of the screen about 2 weeks ago, it is easy to see on any thing with a light background, like hockey. Now it is a distraction every time you see it. I'm going to try the dealer where I bought it first and see where that takes me.Too bad I will be dealing with sharp Canada

Hi guys good news,
i have just had my TV looked at by a professional LCD agent in the UK, a subcontractor of the retailer i bought my TV from.
he has said that the screen and light panels require replacement. due to this being a MAJOR component fault they are changing it under warranty, through Sharp and the retailer.
they have stipulated that a new TV is in order, my new unit will be here in 7 days.

RESULT !!!

sharp know about this problem, so keep at them and ask for a replacement.
post #16 of 68
Sorry to bump this old thread but I've got this with my Aquos purchased in Jan 2007. Has been present over the past few months. Did anyone get anywhere with Sharp if out of warranty as a manufacturing fault (unlikely to make a difference I know)?
post #17 of 68
I'm waiting for sharp to get back to me concerning my d62u.It has a vertical line on the right side of the screen where 4:3 screen ends.And it also has a vertical line in the center.Looks like the panel is made of 2 separate pieces.
post #18 of 68
Interested to see how you go. In all honesty my Dec 2006 (I checked the date!) LC42XD1 has been pretty good and other than the black tending towards purple gives a good image. I wouldn't think of changing but this line down the centre of the screen is getting a little annoying.

I wonder if your line on the right is some degree of screen burn from watching significant 4:3.

I think it is due to burn in.I unplugged it for a while and it almost disappeared.

I've got the same on a now ageing Tosh 32wlt58. Significant screen burn on both sides.

I had this same exact problem with my 42" D62 Sharp. We got the TV about 2 years ago and only noticed the issue about 2-3 months ago. I really like the picture of the TV until this line appeared...
We have the extended warranty from Sears where we got the TV. Service guy (not a Sears tech, they have a TV repair company they use) came out several times, replaced some board in the set that changed when the line was visible but didn't fix the problem. After the fourth service call they agreed to replace the set. Gave us a credit to go to Sears and pick out what ever TV we wanted. I ended up getting a Samsung 46" and the picture is way better.
post #22 of 68
Well I'm looking to jump ship (likely Panasonic PZ90) so will likely sell the TV off on the cheap. Put me seriously off purchasing a Sharp set again (I could handle the banding).
post #23 of 68
I discovered this thread after noticing the same verticle lines on my 42" Sharp Aquos LC-42D62U yesterday. Boy do I feel like a sucker. I bought this for $2100 back in early '06 for what was a good deal at the time.

My lines are:

Two thin lines, one on either side of where the 4:3 aspect image ends.

One, faint but slightly thicker line down the center of the image.

All three lines are only visible wile displaying certain colors. It seems most apparent with green and blue on mine. It sounds like the consensus it defective backlight panels, which sounds correct.

I highly doubt Sharp is going to do anything about it, but I shall try none the less. It is sad that extended warranties are no longer an option considering none of these companies stand by their products. At these prices they really should.

If anyone get any resolve to this beyond an extended warrenty please let us know!

hi fellas,
long time no see,
Ok further to my earlier post of my sharp aquos 42 inch. as stipulated it was replaced with vouchers for another tv i got a sony 46 inch, incredible picture and sound, no worries there.

unfortunately i bought a sharp aquos 32 inch for my conservatory, and now the vertical hold has faulted out and the channels keep rolling, pc on vga input port, ps3 on hdmi, and set top box on scart. now awaiting engineer for repair estimate (under warranty 10 months old).

sharp are crap and when they tell me this is beyond repair i will get another sony. other than that all's fine.

keep plugging away at sharp though, for they know there are issues with there sets, and even if it is out of warranty, a screen failure is no joke, so keep at them and get a replacement.
take care to all and happy new year.

I started this thread a year or so back. Now i have 2 vertical lines. My pictures look worse than the other one in this thread. It looks worse with a blue screen. At the time of these pictures, all i could get was a green screen to show it off. Almost looks like another one starting on the left side.

My warranty was up 2 years ago, so i doubt if anything could be fixed now. I may talk to Sharp just to be sure. Getting worse all the time.

Ouch. Its delamination. Its permanent and needs to be replaced. How was this TV mounted?

It's on it's stand, sitting on a tv stand.

We have a small shelf above the tv, but the bottom picture is so close to the top one it looks like it's sitting on the shelf. LOL. I'll see if i can put a space between the pictures.

Yes, I see the shelf now. It reads like you had the defect from the start, and as the TV aged, it got worse.

Delamination is a known problem with LCD, but not with plasma screens. It is worsened by heat & humidity and is not user repairable.

that sure looks like the banding issue. Back in 2006, the panels from Sharp, (mostly 42") were the culprit. I had 3 Toshiba sets (all used the Sharp panels) that all developed that issue over time. This is caused by the uneven back lighting. The lines that appear are really a shadowing affect of the difference in the back lighting where the "bands" of the back lighting meet. Just do a search on banding. You'll find alot of info on the 2006 Toshiba Regza thread, as well as the Westinghouse thread. Most people complained and either returned the set or got the panel replaced when the lines first appeared. You might be one of the very few that has held on as long as you have to a set with this issue. So that may explain why the lines are getting wider. There was a time when leaving the set off for an extended period of time seemed to help this situation. And I mean a few days, not hours. Good luck. I think the manufactures should own up to this problem and offer a refund or replacement set to anyone with this problem, no matter how long it's been out of warranty. This was a design flaw and they should stand behind it. After three sets and two years, Toshiba has just taken back the last set, and is refunding my money. Being a loyal Toshiba customer, I went right out and purchased another Toshiba set. So far, no bands...

Saturation -- It ran good the first year and started right after the warranty gave up.

QuattroG -- I thought the banding issue the Sharps were having were horizontal bands, not vertical?
