Sony Bravia KDL-46X4500 LED TV Horizontal Lines Problem

[t1tusx]

Horizontal lines appeared on the LED TV Sony Bravia KDL-46X4500. They look like dotted lines and their number is increasing significantly with time.

It was a Sony's top model with LED backlighting in the year 2008.

Here is the photo of the issue:

Any thoughts what can it be?

Definitely one for your local service centre. Give them a call and they can diagnose properly.

Hi,

the panel is failing and will eventually need replacing im afraid, do you still have warranty on this set? as im guessing it will not be a cheap repair, have you tried speaking with the customer information centre, you'll find this in the support tab at the top of the page.

Thanks for the advice. 

Definitely going to visit service center. It’s a pity but warranty is already finished.

I have contacted Sony's support and they also said to go to local service for diagnostic.

Hey. I got the same tv and model. Probably for the past 4 years or so since I bought it. I had the same problem as you. It got so bad that I was about to throw the tv and buy a new one. Then I did a bit of more digging and so it looks like there are so many people around with different problems with sony tvs.

I tried one last thing. I bought a replacement board

Sony 46" LCD TV kdl-46x4500 Part 460FLC6LV0.1 (280754163438)

The company that was selling it has finished the sale already but try to buy it from USA. Just look at the picture and then look for the same image on ebay or somewhere where they sell it.

I am not engineer or electronic enthusiast and I have managed to do the repair all by myself with a help of my friend. Paid about 40 pounds for the board and the problem got fixed. Much easier than buying another 2000 pounds tv or paying 70 pounds for someone to come and have a look at the tv and then pay so much more when they try to fix it. Most shops would tell you that it is the panel which costs almost the same as a new tv. I gave this board replacement a shot and it worked. Worth the money. It had no problems with tv for about 10 months.

Unfortunatelly I started to have another problem, yealoow haze in left bottom corner. Unrelated to the problem before or the board I replaced I think. I done some digging and will order fbu board to replace for another 40 pounds and see if that is going to fix it. It shows how Sony tv's are so bad and noone should ever buy any sony tv in the future. I know I won't. But until the tv I have completely brakes, I will try to fix it for as little money as possible. Good luck. Let me know how you did.

This is the picture of my current problem with the tv:

BTW, the board you need  I think it's called T-CON board. It sits at the back of the screen, in the middle, at the top. It is under all the boards and pannels at the back of the tv when you take the plastic cover off. It will take you a while to get to it and have to unplug  lots of wires and unscrew a lot of boards and parts to get to it. So remember where everything goes.

Hey Manasm,

I am not sure if your post was meant for me or the guy who originally posted the post.

Anyway, I got some info in my post that might help you solve your problem. So have a look. If you didn't drop the tv on the floor or hit it with something that would potentially damage the panel and the tv was working fine before, I'd say you probably should try to change the t-con board. I will be cheaper than to pay some shop to take it away and have a look at it and then try to charge you a lot of money to fix it. If your tv is out of warranty and Sony don't want to help you, you have nothing to loose. Good luck.

Hi forgiven1, not sure if the post was meant for me or to the original poster of the topic.

anyway, I managed to fix my tv, yet again, so mine is still working. But good luck.
