Sony bravia 3 lcd red line top of screen

biffo19

Hi guys,

I changed the bulb on my sony bravia 50" as the old one blew. When I turned vack on my tv the picture was much brighter but im left with a red line a couple of inches wide across the top of my screen and no matter what I do I cant get rid of it. Any one have an idea what to do? Any help would be brilliant. Cheers.

It looks like a shadow caused by something blocking or shading the lamp. The edge is too graduated to be anything else. A fault with the panel would give a sharper more defined edge.

That said it kind of looks like a band caused by a low frequency AC signal on the video ground. Like as if there was a poor ground on the video cable. I presume it remains constant regardless of the signal input used ?

What's the model number of the set ? What were the symptoms of the lamp being faulty ? Did you use an internet guide to help you replace the lamp, if so - which one ? Link ?

Yea it remains constant regardless of the input used. The model number is kdf-50e2010. The lamp light on the front was flashing and I had no picture. When I took out the bulb it was blown. I used the instructions that came with the lamp and had a look at a few videos on the net they were all kind of the same. Does any of this help?

Can these be fixed or replaced? And is it worth my while if they can fixed?

Yes, technically they can be fixed and/or repaired. It is probably one of the polarizers in yours that has a stripe burnt into it from the heat.

Unfortunately it has always been difficult/impossible to get replacement parts from Sony. So most of the ones for sale are used/harvested from broken sets with no guarantee they won't degrade again soon. Even then you will pay a couple of hundred euro for one.

I would start off by contacting Sony. Depending on the age of the set and how much you paid for it, you may be able to wrangle an out-of-warranty remedy from them. In the US they were replacing optical blocks for free (probably under threat of a class action lawsuit) but that was a good few years ago now.

There are certainly people who will repair it for you but I would not bother putting much money into it personally. If you are handy you might consider looking at it yourself. Its a very common problem so if you search online you will find lots of people with the same issue and maybe some of them have come up with their own fix.

Thanks a million for the reply. I'm going to email Sony and see what they say. Nothing to lose I suppose. Any idea which email address or contact details?
