Shadow Problem with my Sharp LCD LC32GD8E

super__d2345 · 21-05-2010, 22:40

I'm having a very weird problem with my TV and it won't go away!

We recently watched Sky Sports HD1 tonight and the logo appears as like a shadow on the top right of the TV screen and won't disappear!

I've tried turning the TV off and on, that didn't work, I've tried different channels and always watching Sky through Scart and trying to watch analogue and I'm still seeing the Sky Sports HD1 logo as a shadow on the TV, This has stuck there now for 15 minutes??

What do i do?

It's very unusual to get image retention on an LCD. Try selecting a blank channel on analogue so you get 'snow', and let the TV dispaly that for a while and see if the image goes away.

super__d2345 · 21-05-2010, 23:20

How long should i leave it on the analogue channel?

First thing is to get the software in the TV reloaded, software corruption is common on that TV, and causes all kinds of strange faults.

And how exactly do you do that?

This is the situation now, I tried doing a snow test for 2 Hours and the channel logo disappeared, then I left the TV unplugged for 4 hours but I'm seeing a slight shadow in the top right of the screen, so whats the problem, shall i ring Sharp? What shall i say?

I'm guessing Sharp will do what all the other manufacturers do & point you to the disclaimer in the manual which tell you to avoid static images; Quite how you are supposed to do that though with Channel logo's is beyond me

super__d2345 · 22-05-2010, 13:49

Anyone know how much Sharp would try and charge me if all it is, is a system reset?

That only applies to Plasma, LCD manuals have no such disclaimer, as the mechanism that damages Plasma screens (and CRT) doesn't apply to LCD.

If it is a retained image, then it there because of a fault - not that you've left it running on a static image.

It's not a customer job, how old is your TV?.

super__d2345 · 22-05-2010, 14:07

Our TV is around 3 years old, so out of warranty

That's not true. LCD can retain an image, fortunately its temporary and will go away of its own accord. You can speed things up by displaying a randomly changing image, like static.

super__d2345 · 23-05-2010, 10:21

Well this cant possibly be image retention or screen burn cos when i woke up, the shadow area is still there!!!

You're talking about something completely different, not the OP's problem.

super__d2345 · 23-05-2010, 17:11

Anybody else understand what could be going on with my TV and is there anyway I could fix it?

If it means getting an engineer, I'll wait a few months and might as well get a new TV.

It means getting an engineer, who's first action would probably be to update the software - failing that, it's most probably the LCD screen duff, which makes it MUCH too expensive to consider.

I wish you luck OP. My Sharp only lasted 18 months. Your 3 years is a lifetime for this manufacturer.

I was lucky to get a brand new set. The new set is only 3 weeks old and I can see the beginnings of the same bloody banding problem on the panel already.

Sharp are crap (in my experience anyway)

As Nigel said if the panel on your telly has gone - it'll render the whole TV uneconomical to repair.

super__d2345 · 25-05-2010, 00:28

Well as i thought, looks like I'll be buying new TV in a few months, Thanks Guys !!

Can you explain this?
Image sticking occurs when a static image causes a charge build up, which means that pixels remain partially polarised. The effect is a shadow image as described by the OP.
Without further investigation I don't see how you can decide in favour of a software fault.

I didn't decide in favour of it, I merely pointed out that it was the first thing to do - as Sharp TV's are VERY prone to software corruption. The most likely problem is a faulty LCD, but you'd automatically update the software first just to make sure.

prking · 25-05-2010, 11:54

I've no desire for an argument, however you told me I was talking about something that was completely different and not the OP's problem!
Given that image sticking is more likely to occur when a static image is displayed for an extended period in warm weather, then I think it should be considered.

You're talking about a mostly theoretical short term phenomena - he's talking about a permanent condition.

I see no relation between those two?.
