Question about Sony KDL-50EX645 50" LED TV 1920x1080, 240 Hz, HDTV

Open Question

Sony KDL-50EX645 purple vertical line between the panel

So I purchase this TV almost a year back and one day a purple vertical line started appearing in the middle of the TV screen. I try everything to fix this and nothing seems to be working. Does anyone know what is causing the issue. Given I have a soon to expire warranty I would like to do something about it as fast as possible. Thank you.

This can be the panel itself, and or the matrix decoder/driver boards. The cost of this type of repair can approach the cost of a new set. From your description, I am thinking it is the panel itself that has failed.

Parts for your set are from Sony only because there is no third party manufacturing for these types of parts and assemblies.

Usually, when these types of sets become defective they are usually not worth servicing. During warranty the manufactures generally give a new set to the client, or they give a re-built set which has been built up using parts and modules from other sets that came back for service and had different types of problems.

If you know a tech is is good at servicing these types of set, maybe he can find a number of scrapper set of the same model to take parts from. You just have to hope the ones he finds have the same types of fault.

SOURCE: Sony Bravia KDL-40w4100 vertical line issue

Ok after over a year i figured out it was the tcon board. Good luck getting finding one. The first one i ordered from shopjimmy was faulty, didn't realize until after the warranty so i ate the cost of it (honestly i thought that it was good and there was another thing wrong with the tv) so i said wtf and bought one last week from ebay. Bam! it works great!!!

Vertical blue stripe on my Sony KDL-40S4100


Was the telvision impacted? Usually a Blue line on various tv sets such as Sharp and Sony can also indicate a firmware upgrade being needed. Try that first, as to a panel if this is a panel we have in stock cost could be between $200-400 for the part that part cost from Sony coulb be double if you need to purchase new.

My dad has Sony Model KDL-42V4100 that is about 3 years old. It has a smoky vertical streak that almost looks like water has run down the screen---any ideas on what it is or how to fix it. It appears...


This is called "clouding". It is very common with a lot of the lcd panels. I suugest going to sonys e support website to see if it might still be under warranty. I have a sony lcd tv that I purchased back in 07 and its under warranty until october 2012. If it is still under warranty then sony will fix it for free.

It sounds like you might have a defective LCD panel. Your warranty for your TV is 18 months. Some of these models the warranty was mis-printed and said only 12 months.

Vertical line on teh left side of the screen


It definately looks like a mechanical defect with the screen. If you see the line when the set is shut off this means that the screen may have a crack in it, or there is a defect in the substrate.

This type of fault is fixed by replacing the screen assembly. The cost of this would not be worth it.

Thin vertical red line


This maybe the symptom of a bad Panel. One Vertically This line is 99% bad panel. Call your warranty provider or SONY tech support if purchased under 2 years.
