Question about Sony Bravia KDL-42V4100 42 in. LCD TV

1 Answer

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 some more smoky streaks are appearing across the top of the screen. Nothing has been spilled on the screen. They are not visible when the tv is off---they are most visible on a blue screen. Thanks for any advice and opinions!

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.

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!!!

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER
Hoping this will help in solving the problem, take care...

Blinking black streaks run right to left of the monitor. A new cable vision box was installed. The problem continues even with a DVD. The Sony Bravio KDL 46 BR 4 TV is two years old.


this problem is coming from your digital video board this board is the one in charge of displaying the image into the screen get the part number of the board to find the right part I found a only store that has a lot of your tv parts

I also have a 2 yr old Sony KDL32xbr4 that now has multi-colored vertical lines on the screen. I contacted Sony and they say they have "no known issue" of this sort for this model. I find this rather puzzling since I have found numerous postings on the web. They told me to try the factory reset. Whatever. Might as well have said "don't buy a Sony". 2 years! $1300 for a tv and it lasts 2 years! Makes me sick to my stomach.

The panel or TCON board has failed, the solution is the same replace the panel. Not worth the cost, get a new TV
