Hi There,

I have a 32" Samsung LCD that I purchased 15 months ago. All has been well until last night I switched it on and saw the following:
- About a third of the way down from the top of the screen, a defined horizontal yellow line
- Vertical yellow lines across the width of the TV that fade as the reach the bottom

the colour of the lines do vary depending on the image source and is visible on all inputs (Sky / DVD / Wii / unused AV)

I have checked all connections but suspect this is not the problem due to it occurring on all sources.

I have disconnected the tv from the mains but the problem remains.

I have taken a photo to assist:

Any ideas of the problem / fix?

Many thanks in advance

Gareth

Most likely the LCD panel I'm afraid.

There is a chance that it's a fuse failure on the LVDS board (which is part of the panel anyway), and I've heard of people who have managed to replace them - it's a tiny SM device, if it exists on this particular set.

Thanks Nigel,

Although it's the answer I didn't want to hear, I appreciate your time, knowledge and advice.

Although out of Samsung's warranty, I will try and pursue the statatory latent defect route. Are you aware of this being a common fault? 15 months seems a totally unreasonable amount of time in which to develop a fault of this magnitude.

Thank again,
Gareth

Give Samsung a call.

Mate of mine has a 3 year old 60" 4 Series and the HDMI sockets just failed 3 months after the 3 year warranty he bought expired. Samsung have offered to come repair it for free as it's only just out of warranty. They've also said they'll replace the TV with the equivalent 8-Series if they can't fix it!

When I called them for an issue with my 6-Series (which turned out to be an undocumented "feature") they could not have been more helpful.

Thanks for the heads up Dr Phlox, hope they take a similar approach.

It's worth a try, manufacturers are sometimes fairly helpful.

This is a fairly common fault which can have many causes. Dead fuses on the LVDS board as Nigel states, dud display panels, and similar effects can be caused by faulty backlights.

Same goes for when these flat panel TVs refuse to switch on and simply leave a red standby light switched on. Again, this can have many causes, the most common being crap capacitors (crapacitors I prefer to call them) in the power supply unit.

Unfortunately, the general reliability of these flat panel display TVs seems to not be very good. they have a relatively short lifespan. Some say that generally they are getting more and more unreliable, others say the opposite. Unfortunately, I don't feel I have had enough experience of flat panel display TVs to make a judgement on whether they are getting more or less reliable, but I would guess its a case of the former, as the technology develops they would logically be ironing out any teething problems they seem to have with this fairly new technology.

It's only the cheap ones which have reliability problems, unfortunately Samsung fall in to that group

Like Thomson, they fitted the cheapest possible capacitors in the PSU, and these common fail and cause many other faults when the do.

I've just rang Samsung and explained the situation, they have advised I "take it to my local Samsung accredited repair centre, thank you bye..."

I protested that the set is only 15 months old and according to advice from a TV engineer, this is a known fault potentially with the main board and should certainly not be failing, rendering the set unusable within such a short period of usage.

They did not argue, their customer care team are calling me back before 4pm today. Hopefully with some good news.

Thanks for your advice guys, much appreciated. I'll let you know how it goes

Evidently another customer service team who are so bad they don't understand the basic concepts of human rights . . .

Couldn't they have put you through to Samsung UK's technical department? If such a department exists? Surely the person at the call centre should have used their intelligence and automatically put you through to their tech team as that is the nature of your enquiry?

Human rights is a purely imaginary concept anyway, and nothing whatsoever to do with this.

You're assuming a LOT there, that such a team exists, and that the CS has the capability to forward your call.

Success... Spoke to a guy in Samsung's Tech Team - Although they wont admit its a common symptom, they are willing to repair the fault free of charge.

Thanks again to all that posted.
